Characteristics of the female pelvis
What are the 3 differences between a male and female pelvis?
Female pelves are larger and wider than male pelves and have a rounder pelvic inlet. Male iliac crests are higher than females, causing their false pelves to look taller and narrower. The male sacrum is longer, narrower, straighter, and has a pronounced sacral promontory relative to the female sacrum.
What are the features of the pelvis?
The pelvis consists of paired hipbones, connected in front at the pubic symphysis and behind by the sacrum; each is made up of three bones—the blade-shaped ilium, above and to either side, which accounts for the width of the hips; the ischium, behind and below, on which the weight falls in sitting; and the pubis, in …
Which features distinguish the male and female pelvis?
What is the typical female pelvis?
The female pelvis is comprised of the uterus, ovaries, bladder, rectum, surrounding vasculature, and ligaments.
What are the functions of female pelvis?
The pelvis plays important functions in (1) locomotion, as body weight is transmitted to the lower limbs through the pelvic girdle, (2) childbirth, as the human neonate must pass through the birth canal, which lies within the pelvic girdle as the baby exits the body, and (3) support of abdominal organs which are held …
What are the 5 functions of the pelvis?
The pelvic floor muscles play five important roles in the body:
- Organ support. The pelvic floor muscles support our bladder, uterus, rectum, and important abdominal organs against gravity and any added downward pressure.
- Stability. …
- Sphincteric function. …
- Sexual Function. …
What are the 5 main differences between a male and female pelvis?
While in the male it is heart shaped, and narrow. A male pelvis has a v-shaped pubic arch that is approximately <70°. The pubic arch is usually wider in the female pelvis at about >80°. The coccyx in the male pelvis is projected inwards and immovable while a female pelvis has a flexible and straighter coccyx.
How do the distinct characteristics of the female pelvis make childbirth easier?
The lesser pelvic cavity is wider and more shallow in females, and the pelvic outlet is larger than in males. Thus, the greater width of the female pelvis, with its larger pelvic inlet, lesser pelvis, and pelvic outlet, are important for childbirth because the baby must pass through the pelvis during delivery.
What is the structure of the pelvis?
The pelvic spine consists of the coccyx and sacrum. The pubic bone, the ischial bone, and the iliac bone join together on each side and are called the innominate bones. Thus there are 2 innominate bones, one on the right side and the other on the left side. The two-part of the pelvis is forming a pelvic ring.
What are the 4 types of pelvis?
Although pelvises can be classified according to diameter, in obstetric practice they are often divided into 4 main types: gynecoid, android, anthropoid, and platypelloid, based mainly on the shape of the pelvic inlet .
What 4 things are contained in the pelvic cavity?
This landmark begins at the level of the sacral promontory posteriorly and the pubic symphysis anteriorly. The space below contains the bladder, rectum, and part of the descending colon. In females, the pelvis also houses the uterus, fallopian tubes, and ovaries.
What are the 8 landmarks of the pelvic brim?
- 1 Introduction.
- 2 Iliac Crest.
- 3 Greater Trochanter of the Femur.
- 4 ASIS.
- 5 PSIS.
- 6 Pubic Symphysis.
- 7 Other.
- 8 Validity.
What are the 3 pelvic bones?
What is the pelvis?
- Ilium. The broad, flaring portion of the hip bone (the crest of the pelvis).
- Pubis. The lower, posterior part of the hip bone.
- Ischium. One of the bones that helps form the hip.
What is the opening in the pelvis called?
The large opening in the anteroinferior hip bone between the ischium and pubis is the obturator foramen. This space is largely filled in by a layer of connective tissue and serves for the attachment of muscles on both its internal and external surfaces. Several ligaments unite the bones of the pelvis (Figure 3).
Where is the female pelvis located?
What is the female pelvis? The pelvis is the lower part of the torso. It’s located between the abdomen and the legs. This area provides support for the intestines and also contains the bladder and reproductive organs.
What is difference between pelvic and pelvis?
The pelvis (plural pelves or pelvises) is the lower part of the trunk, between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis, or pelvic skeleton).

How many bones are in the pelvis?
There are three bones of the pelvis: the hip bone, sacrum and coccyx. These bones connect the axial skeleton to the lower limbs, and therefore play a role in bearing the weight of the upper body. These bones also act as attachments for many muscles and ligaments within the pelvis and lower limbs.
What type of bone is the pelvis?
1. Flat Bones Protect Internal Organs. There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis).
