The male pelvis is more adapted to bear the heavier build of the upper body and for stronger muscle attachment, while the female pelvis is adapted to provide enough space for the birth canal (or birth passage) in the region. This sheet of muscle is also called the pelvic diaphragm, and it separates the true pelvis from the perineum underneath. Male Pelvic Bones: Female Pelvic Bones: Label The Major Parts Of The Diagram Below. Therefore, this is the key difference between male and female sacrum. Note the female pelvis has a wider flair of iliac crests, has a more spherical true pelvis, and the pubic arch is wider than the male. The piriformis muscle origins from the anterior aspect of the middle three segments of the sacrum on either sides. Lateral compression injuries cause fractures in the pubic rami on both sides, or dislocation at the symphysis with fractures on one side. This causes the sides of the male pelvis to converge from the inlet to the outlet, whereas the sides of the female pelvis … Skeleton is a very important part of the body as it basically provides the framework that supports the body and maintains its shape. There are several diagnostic criteria for differentiating a male from a female pelvis: The female pelvis is larger and broader than the male pelvis, which is taller (owing to a higher iliac crest), narrower, and more compact. The pelvis demonstrates many sex differences among mammals. Falls in the leg may cause central dislocation of the hip, pushing the head of the femur through the acetabulum. Question: ACTIVITY 4: THE HUMAN PELVIS Compare The Shape Of Human Pelvic Bones Below. • Obturator foramen of male pelvis is round while, in females, it is oval. We have a range of male and female pelvis anatomy models ranging from budget pelvis models showing the simple anatomical structure of the pelvic region to more advanced models including the lumbar spine, nerves, blood supply and pelvic floor. Core Difference between Male and Female Pelvis In Point Form Male pelvic is narrower and smaller while the female pelvis is wider and larger The male pelvic bone is heavier, taller, and thicker while the female pelvic bone is lighter, shorter, and thin. Pelvic Inlet. Related bone structure is also found in birds and dinosaurs. A) the pelvic inlet is wider B) the female pelvis has a smaller pelvic outlet C) the pelvic inlet is rounder D) the pubic angle is wider. The female pelvis is adapted for childbirth and is broader, with a larger subpubic angle, a rounder pelvic brim, and a wider and more shallow lesser pelvic cavity than the male pelvis. The female pelvis also has a much wider placement of the ischial spines. The functions of the pelvis are protecting the pelvic viscera, supporting the weight of the body, enabling the waling ability with the fixed hip joints, providing surfaces for attaching muscles, and providing bony support for the birth canal in females. In general, the male pelvis is more tall and narrow while the female pelvis is more broad and flattened. Additionally, the angle beneath the ischia bones (the pubic arch) forms a much more acute angle in the male (<90 degrees) while in the female the pubic arch forms an obtuse angle (>90 degrees), and the pubic arch is higher in the male. The part of the cavity above the pelvic brim is called the false pelvis (greater pelvis/upper pelvis), and it accommodates lower abdominal contents such as the sigmoid colon and coils of small intestine. What is the difference between Male and Female Pelvis? The superior pubic ramus runs as a bony extension upwards and laterally from the body of the pubis, and joins the acetabulum. The pelvic brim lies at an angle of 60° to the horizontal. Describe the pubic angle of the female pelvis as compared to the male pelvis (give only female pelvic characteristics) -broader angle (80-90 degrees) -more rounded & arched than the male pelvis Give one function of the female pelvis So realistically, and medically speaking, it is not pelvis ascites, rather an abdominal issue; discomfort in the abdomen considering ascites would be fluid build-up when you look at the abdomen. Compare the Difference Between Similar Terms. • The bones of male pelvis are heavier, thicker and stronger while the bones of female pelvis are lighter and less dense. The female sacral vertebra is shorter and wider compared to the male sacrum. Picture 2: Features of the hip bone (right, posterolateral aspect). Each pubis consists of a body and two rami. These three bones fuse at a cup-shaped concavity called the acetabulum which articulates with the head of the femur to form the hip joint. Females have less massive, lighter and more expanded pelvic bones. The male pelvis is stronger and made of better defined muscle marking. The inner surface is concave medially, and forms the iliac fossa which demarcates the lateral wall of the greater pelvis (the upper division of the pelvis). Picture 3 & 4: The true pelvis and the false pelvis. Pelvic Inlet/Brim Has a … Materials and methods: A total of 19 healthy women underwent pelvic MR scans on 3T and 1.5T scanners. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. The true pelvis is wide and shallow in the female, and the pelvic inlet, also known as the superior pelvic … The pelvis is composed of four bones; the two hip bones laterally and anteriorly and the sacrum and coccyx posteriorly. The lower part of the body forms a laterally directed prominent rough surface named the ischial tuberosity. Each pelvic bone (hip bone) is made by the combination three bones namely, the ilium, pubis, and ischium. Picture 1 : Location of Pelvis (with a fracture). The female pelvis is designed for the function of child birth, so that the pelvic cavity is shallow and it has sufficient space to carry a baby. The greater sciatic notch is formed between this spinous process and the posterior inferior iliac spine. The health information provided on this web site is for educational purposes only and is not to be used as a substitute for medical advice, diagnosis or treatment. At the lower end of this surface is a bony ridge extending from behind forwards, named the arcuate line. Few centimeters below this is another bony prominence called the anterior inferior iliac spine. The female pelvis tends to be larger and wider than the male because of the female reproductive system. Compared to the male, the female pelvis is wider to accommodate childbirth. The distance between the ischium bones is small in males. The ischium is located in the posteroinferior aspect of the pelvis, and is comprised of a body and a ramus. First, the female pelvis is shallower and wider when compared to the male pelvic girdle. Some of these differences are compared in the table below. This corresponds to the S2 vertebral level. It forms an irregular bony girdle connecting the lower limbs to the trunk. Just note that the terminal ileum, cecum and sigmoid colon are found within the greater pelvis in both sexes. The female inlet is larger and oval in shape, while the male sacral promontory projects further (i.e. Identify By Letter (A Or B) Which One Is Belongs To The Male And Which To The Female. The pelvis is positioned in an anteriorly tilted manner, so that in the anatomical (erect) position, the anterior superior iliac spine and the upper margin of the pubis lie in the same vertical plane. The bony pelvis is made up of two pelvic bones – the sacrum and the coccyx. The differences between a male and female pelvis are compared below. A. The upper end of the sacrum has a forwardly projecting prominence named the sacral promontory. • The female pelvis is less massive than the male pelvis. It is smaller and narrower with heavier and … • Males have heart-shaped pelvis inlet and v-shaped pubic arch, while females have oval shaped pelvic inlet and wider pubic arch. Few centimeters below this point is another bony prominence called the posterior inferior iliac spine. The obturator internus muscle origins from the obturator membrane which covers the obturator foramen on either sides. The female pelvis is broader and larger than the male pelvis to provide a comfortable environment for fetus development. The pelvis in males and females differ from one another in various features, due to the functional distinction between the two sexes. Fractures of the pelvis may occur due to direct trauma or due to compression injuries. The piriformis muscles and the sacrum together form the posterior wall of the pelvis. The posterior surface of the body has a sharp ridge extending laterally, named the pectineal line. The bony cavity formed by the combination of these bones is the pelvic cavity, and is divided into two parts by the pelvic brim (pelvic inlet) which is the oval shaped demarcation made by the continuation of the pectineal line of the pubis along with the arcuate line of the ilium, and the sacral promontory. C. The obturator foramen is more oval in a female. Male Pelvis: Female Pelvis: 1. The pubis and the ischium are separated by an oval opening called the obturator foramen. Which of the following describes the female pelvis compared to that of the male? The male pelvis is heavier, the inlet is narrower and the outlet bony angle is more acute than in the female pelvis. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } A. Male Pelvis : Female Pelvis : Size Male pelvis is smaller and narrower with heavier and thicker bones. Male: narrower; Female: broader; Pubic Bones. Picture 5: Joints and ligaments of the pelvis (anterior view). Comparison of the Female and Male You can see from the following comparisons that the female pelvis is designed to birth a baby and the male pelvis is not. All rights reserved. Terms of Use and Privacy Policy: Legal. But owing to this position, the scrotum provides the optimum temperature for sperm production. On the other hand, the female sacrum is shorter and wider. The female pelvis is larger and broader than the male pelvis which is taller, narrower, and more compact. It has a central mass and two lateral masses (forming the ala) on either sides. Moreover, cross sectional study and an overview of the bones have been put forth. Male: narrower, heart-shaped; Female: open, circular; Sciatic Notch. The female pelvis has a wider sciatic notch and the acetabula are wider apart compared to the male pelvis. The sacrotuberous ligament extends from the ischial tuberosity to the sides of the sacrum and coccyx, and it converts the lesser sciatic notch into an opening called the lesser sciatic foramen. MUSCLES AND ORGANS In the commencement of this section, cross sectional anatomy and five bones along with hip bone has been delineated. The posteriorly located body has a spinous process in its upper end. The male pelvis is more adapted to bear the heavier build of the upper body and for stronger muscle attachment, while the female pelvis is adapted to provide enough space for the birth canal (or birth passage) in the region. Has a sacrum that is wider, shorter and less curved. The situation is different for the female pelvis, which is wider and larger to enable childbearing. Some people divide the pelvis into a greater (or false) pelvis and lesser (or true) pelvis. • Ischial spine of male pelvis is projected inward while that of female pelvis is projected outward. • The anterior iliac spines of female pelvis are widely separated, thus giving the females the greater prominence of the hips. All of these changes occur in order to support the uterus throughout the period of pregnancy and assist with the normal mechanism in childbirth. Before puberty, usually, both sexes have the general characteristics of a male pelvis. D. The female iliac bones are less flared. Male and female pelvis Note the differences in the bony pelves of the male (left) and female (right). Furthermore, the curvature of the sacrum is higher in males than the females. It provides attachment to some important muscles in the region, and forms a cavity which accommodates several important internal organs. These muscles origin in continuity from the body of the pubis, along a tendinous arch over the obturator internus fascia, and the ischial spine. 37) Compared to the male pelvis, the female pelvis A ) is larger B) is heavier C) has a greater angle inferior to the pubic symphysis. the male inlet is more heart-shaped). • Female pelvis has a shallow pelvic cavity, and it is wider than male pelvis. Female pelvis. The male pelvis tends to be relatively long and narrow, with a longer and more conical pelvic cavity compared to the female pelvis. If they did, they would be in the way during childbirth. This bone also acts as a protective structure for the female reproductive system including uterus and ovaries and also for the bladder and rectum. Coming from Engineering cum Human Resource Development background, has over 10 years experience in content developmet and management. The difference between the male and female pelvis The pelvis is a bony ring, interposed between the moveable vertebrae of the vertebral column which it supports, and the lower limbs upon which it rests. • Due to the more delicate bones of the female pelvis, the muscle attachments are poorly marked than those of the male pelvis. Thus, it is also a significant difference between male and female sacrum. Describe the pubic angle of the female pelvis as compared to the male pelvis (give only female pelvic characteristics) 80‐90 degrees, broader Give one function of the female pelvis hold reproductive organs; Adapted for childbearing The two sacroiliac joints are synovial joints, and are further strengthened by the very strong posterior sacroiliac ligaments which run along the posterior aspect of the joint. The greater width of the female pelvis results in a larger subpubic angle. The most superior point of this curved crest is at a position just behind its midpoint, and corresponds to the L4 vertebral level. 3.A male pelvis has a v-shaped pubic arch while a female pelvis has a pubic arch that is wider. • Males have heart-shaped pelvis inlet and v-shaped pubic arch, while females have oval shaped pelvic inlet and wider pubic arch. The posterior aspect of the ala is curved inwards to form a broad, rough region which is divided into two surfaces: the sacropelvic surface and the auricular surface. Each of these muscles, together with their counterparts in the opposite side, form a gutter extending from above downwards, forming a sling around the pelvic visceral organs. The angle of the female pubic arch is smaller. The female sacrum is wider, more uneven, less curved and more backward rotated. Its main purpose is childbearing, and thus, the structure of the female pelvis is made so that it supports this function. The muscular impressions are only slightly marked on bones. Moreover, sacrum, coccyx and femur have been explained. The sacrospinous ligament extends from the ischial spine to the sides of the sacrum and coccyx, and it converts the greater sciatic notch into an opening called the greater sciatic foramen. • Unlike females, male reproductive organs like testicles are not protected by pelvis, as they lie outside the pelvis. Larger and broader with iliac crests flaring outward; Overall design is wider. Results: Pelvic capacity was significantly lower in males (460.0 +/- 16.7 cm3) than in females (634.8 +/- 22.0 cm3; p < 0.0001), and level of the levator ani compared to the upper edge of the pubis was significantly lower in males than in females. • Subpubic arch of male pelvis is more acute while that of female pelvis is wider.

The distance between the female ischial spines is greater. Male pelvis has a V … Comparisons of Male and Female Pelvis. The body is located close to the upper margin of the acetabulum, and a flat plate-like ala extends upwards and laterally from the body. The ala of each ilium consists of two surfaces: the inner (medial) surface and the outer (lateral) surface. The uppermost margin of the ala is known as the iliac crest, which can be felt by palpating the lower parts of the flank on either sides. Basically it supports the moveable vertebrae of the vertebral column, and it rests upon the lower limbs. The coccyx is also a roughly triangular bone formed by the fusion of three to five vertebrae, and it articulates with the lower end of the sacrum to form the sacrococcygeal joint. The outer surface is convex laterally and provides attachment to the gluteal muscles in the region. The pelvis is a bony ring found in between vertebral column and lower limb in the body. The outlet of the females’ pelvis is also wider than that of males to facilitate vaginal birth. Additionally, male and female pelvis have been compared. The auricular surface of each ilium articulates with the ala of the sacrum, to form the sacroiliac joints on either sides. may also get injured due to penetration by bone fragments. 1.A male pelvis is smaller and narrower while a female pelvis is wider and roomier. No muscle crosses the pelvic brim. The inferior pubic ramus extends downwards and laterally to join the ramus of the ischium. Hence stronger muscles in males are attached to its markings. The pelvis is located between the fifth lumbar vertebra and the femoral heads. The biggest differences in the pelvises of men and women are the sizes of the pelvic inlet, sciatic notch and the angle of the two pubic bones that meet at the front. The male pelvis has more deep and narrow cavities than those of the female pelvis. • The bones of male pelvis are heavier, thicker and stronger while … All of the following are true about the female pelvis compared to the male pelvis EXCEPT _____ asked Sep 8, 2016 in Anatomy & Physiology by Dougie-Fresh. However, after puberty, the pelvis acquires certain sexual characteristics peculiar to it in adult life. The pelvis is a basin shaped bony structure formed by the combination of two pelvic bones (hip bones or innominate bones) and the sacrum. The pubis is located in the anteroinferior aspect of the pelvis. The lower end of the true pelvis is called the pelvic outlet, and it is demarcated anteriorly by the lower margin of the ischiopubic rami, laterally by the ischial tuberosities and the lower margin of sacrotuberous ligaments, and posteriorly by the tip of the coccyx. Because of this, a female’s pelvis is typically much broader as compared to a male pelvis. It is strengthened and supported by several joints and ligaments. As such the greater pelvic girdle is wider in females with flared iliac crests and the anterior superior iliac spines farther apart (DeSilva & Rosenberg, 2017). The posterior end of the iliac crest also forms a bony prominence called the posterior superior iliac spine, which can be felt at the dimple just above the buttock on either sides. What is the difference between Male and Female Pelvis? The anterior end of the crest forms a bony prominence called the anterior superior iliac spine, which can be palpated in the lower parts of the anterolateral aspect of either flank. The greater pelvis is a part of the abdomen study section, we won’t spend too long on that here. The bodies are located medially, and are joined with one another by a cartilaginous joint called the symphysis pubis which lies in the midline. The anterior surface of the body has a bony ridge named the pubic crest, in its upper part. The lesser sciatic notch is formed between the ischial spine and the ischial tuberosity.
