Antenatal Care Module: 6. Anatomy of the Female Pelvis and Fetal Skull
I must put my hand on my hip at least a thousand times a day. I don't know what it is—it's a habit that I can't seem to break. Mostly, I think it's because I never quite know what to do with my hands if I'm just standing. But there's something to be said for resting your hand on something sturdy—even when the sturdy thing is you! The pelvic girdle may look like one giant bone, but it's actually made of three. The pelvic girdle connects the bones of the lower limbs to the axial skeleton by different attachment sites, and supports the vertebral column.
The hip bones are a major component of the pelvic girdle. Check out our free eBook to learn more! And I'm going to be honest: I find the pelvic girdle to be one of the most beautiful structures in the entire body. When we're born, we have over bones. As we grow, some bones fuse together, leaving us with by the time we're adults. The pelvic girdle, as I said above, is made up of three fused bones: the ischium, the ilium, and the pubis.
The pubis forms the anterior part of the pelvic girdle. It is a flattened, irregular-shaped bone that articulates with the pubic symphysis, a cartilaginous joint. Image captured from Human Anatomy Atlas. The ilium is the largest and most recognizable part of the pelvis: it looks like the top of a wing. If your hip bones "stick out" are visible through your skin , it's usually the ilium you're seeing; they protrude outwards. The ilium articulates with the sacrum, forming the posterior wall of the pelvic cavity.
The iliac crest, the superior-most area of bone, is the attachment site for several muscles, including the latissimus dorsi and gluteus maximus. The ischium, located directly below the pubis, forms the bottom of the "wing. The obturator canal is the attachment site for the obturator muscles, as well as nerves and blood vessels. The femur and the pelvic girdle have a very special relationship—it's special in that it allows you to walk. Take a look at the femur see image.
The helmet-like structure highlighted in teal is the head. Many bones have a head. The pubis, ischium, and ilium have a hand in creating the acetabulum, the deep, hemispherical, cup-shaped depression the socket with which the head of the femur articulates.
The head of the femur fits perfectly in this cavity; its ball shape allows it to roll the femur, rotating it in a way that facilitates walking. Ligaments hold the bones together. In addition to supporting the vertebral column and allowing you to walk, the pelvic girdle—along with the sacrum and the coccyx—forms the walls of the pelvic cavity, which contains and protects some of the reproductive, digestive, and urinary organs.
The pelvic girdle is delicate and shallower in the female pelvis than the male—the ilia are less sloped, and the superior aperture is more circular. Are you an instructor?

The pelvis is the lower part of the torso. This area provides support for the intestines and also contains the bladder and reproductive organs. There are some structural differences between the female and the male pelvis. Most of these differences involve providing enough space for a baby to develop and pass through the birth canal of the female pelvis. As a result, the female pelvis is generally broader and wider than the male pelvis.

The pelvic girdle is a ring-like bony structure, located in the lower part of the trunk. It connects the axial skeleton to the lower limbs. In this article, we shall look at the anatomy of the pelvic girdle — its bony landmarks, functions, and its clinical relevance. Ligaments attach the lateral border of the sacrum to various bony landmarks on the bony pelvis to aid stability. Fig 1 — The pelvic girdle is formed by the hip bones, sacrum and coccyx. The strong and rigid pelvis is adapted to serve a number of roles in the human body. The main functions being:. The junction between the greater and lesser pelvis is known as the pelvic inlet.

The ilium is the uppermost and largest bone of the pelvis. It articulates with the sacrum, ischium, and pubis. The human ilium is divisible into the body and the ala, or wing. These two parts are separated on the superior surface by a curved line known as the arcuate line, and on the inferior surface by the margin of the acetabulum. Ilium : The ilium is the uppermost bone of the pelvis and extends laterally.
Over the coming months, we will be offering teaching modules to allow users of Hitachi MRI scanners to advance their positioning skills and review the anatomy that should be seen on some common MRI exams. Our intention is to discuss and review the anatomy that is most often seen, and the positioning that is most often used in your MRI studies. Good positioning skills are needed to ensure the best possible image quality for your studies.
Female Pelvis Overview
Pelvis , also called bony pelvis or pelvic girdle , in human anatomy , basin-shaped complex of bones that connects the trunk and the legs, supports and balances the trunk, and contains and supports the intestines , the urinary bladder , and the internal sex organs. 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 front. All three unite in early adulthood at a triangular suture in the acetabulum , the cup-shaped socket that forms the hip joint with the head of the femur thighbone. The ring made by the pelvis functions as the birth canal in females.SEE VIDEO BY TOPIC: Normal female pelvis from a laparoscope by Dr Raewyn Teirney
If you create an account, you can set up a personal learning profile on the site. In this study session you will learn about the bony structures with the most importance for the pregnant woman and the baby she will give birth to. The bones of the skeleton have the main function of supporting our body weight and acting as attachment points for our muscles. There are certain key landmarks in the anatomy of the female pelvis and the fetal skull that we will show you in this study session. Knowing these landmarks will enable you to estimate the progress of labour, by identifying changes in their relative positions as the baby passes down the birth canal.
3D Skeletal System: The Pelvic Girdle
Growth and development of the female pelvis pictured from the front, top row; and from above, bottom row from birth to 80 years of age. The opening in the pelvis widens during puberty then narrows again later in life. We can all thank our mothers for our big brains. In the past, scientists studying how age alters the human pelvis have analyzed 2D depictions of the pelvic bones. The scans allowed the researchers to create 3D animations of each pelvis.
When the primitive human evolved from walking on all fours to an upright position, changes occurred in the spinal column and the pelvis. The spine became curved and the pelvis tilted, giving a curve to the birth canal. Caldwell and Molloy cited in Silverton classified four types of female pelves which were appropriate for the vast majority of women. The primary function of the pelvis is to allow movement of the body, especially walking, running, sitting and kneeling. A woman's pelvis is adapted for childbearing in that in comparison to the male pelvis the brim is rounder and wider.
The Pelvic Girdle
The pelvis forms the base of the spine as well as the socket of the hip joint. The pelvic bones include the hip bones, sacrum, and coccyx. The hip bones are composed of three sets of bones that fuse together as we grow older. The parts of the hip bone are:.
Anatomy of the Pelvis
Women have wider hips than men because their pelves must allow for the birth of large-brained babies. Nevertheless, many female pelves are still not wide enough, which can result in difficult births. Traditionally, the human pelvis has been considered an evolutionary compromise between birthing and walking upright; a wider pelvis would compromise efficient bipedal locomotion. But this hypothesis has now been called into question: According to new studies, wide hips do not reduce locomotor efficiency.
Outline Pelvic Landmarks. Discuss the physiology of the menstrual cycle and describe hormonal changes that occur during the various ovulatory and endometrial phases. Describe the development of the ovum and its passage from the ovary into the uterus. Understanding the anatomy and physiology of the female genital organs is important for understanding the pathophysiology of the female pelvis. Many pelvic landmarks, ligaments, and muscular structures within the pelvis are important to know to differentiate normal reproductive organs from muscular and vascular structures.
