What bones make up the pelvic girdles?
In discussing the pelvis, a distinction can be made between the "pelvic spine" and the "pelvic girdle." The pelvic girdle, also known as the os coxae, Latin for “bone of the hip,” consists of the fused bones identified individually as the ilium, ischium, and pubis.
What are the 4 pelvic bones?
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 bone is not part of the pelvic girdle?

What type of bone is 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). The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.

What is the function of the pelvic bones?
The bones of the pelvis are a critical part of the central portion of the skeleton. They serve as a transition from the axial skeleton and the appendicular skeleton of the lower body, serving as an attachment point for some of the strongest muscles in the human body while withstanding the forces generated by them.
What are the three components of hip bone?

What are the bones of the pelvic girdle?
Structure of the Pelvic Girdle. The bony pelvis consists of the two hip bones (also known as innominate or pelvic bones), the sacrum and the coccyx. Sacrococcygeal symphysis – between the sacrum and the coccyx. Pubic symphysis – between the pubis bodies of the two hip bones.
Where is the pelvic girdle located?
The Pelvic Girdle. 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.
What is the boundary between the greater pelvis and the lesser pelvis?
The pelvic inlet marks the boundary between the greater pelvis and lesser pelvis. Its size is defined by its edge, the pelvic brim. The borders of the pelvic inlet: Posterior - sacral promontory (the superior portion of the sacrum) and sacral wings (ala).
What is the name of the symphysis between the sacrum and the coccyx?
Sacrococcygeal symphysis – between the sacrum and the coccyx.
What is the term for the joint between the pubis and hip bones?
Pubic symphysis - between the pubis bodies of the two hip bones.
What is the iliopectineal line?
Iliopectineal line – the combined arcuate and pectineal lines. This represents the lateral border of the pelvic inlet.
What is a false pelvis?
Greater pelvis (false pelvis) – located superiorly, it provides support of the lower abdominal viscera (such as the ileum and sigmoid colon). It has little obstetric relevance.
How many bones are there in the pelvic girdle?
As we grow, some bones fuse together, leaving us with 206 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.
What is the pelvic girdle made of?
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!
What is the relationship between the pelvic girdle and the femur?
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. What's special about this particular head is its role as the ball in the ball-and-socket hip joint.
What is the largest part of the pelvis?
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.
Which is shallower, the pelvic girdle or the superior aperture?
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. Be sure to subscribe to the Visible Body Blog for more anatomy awesomeness!
Which organs have a hand in creating the acetabulum?
Image captured from Human Anatomy Atlas. 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.
What is 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.
