What are the major regions of the hip bone?
Now let’s talk about each major region of the hip bone, starting with the ilium. The ilium makes up the superior (or upper) region of the hip bone, and it is named after a Latin word that means “flank” or “entrails,” because that’s what it supports.
What are the lines on the hip bone for?
These lines provide attachment for gluteal muscles. Iliac fossa – When you flip the hip bone around and look at the medial (inner) view, you’ll notice the large depression at the anterior region, called the iliac fossa. This is where the iliacus muscle attaches.
How can I learn more about hip bones anatomy and physiology?
Take a free hip bones anatomy quiz to test your knowledge. In addition, you might want to watch our anatomy and physiology lectures on YouTube, or check our anatomy and physiology notes.
What is the hole in the hip bone called?
Obturator foramen – These two rami of the pubis join the ischium, forming a large hole in the hip bone called the obturator foramen. The word foramen refers to a hole in a bone, and this is the largest “bone hole” in the human body. This huge hole allows for the passage of the obturator artery, vein, and nerve.
At what location do the three bones of os coxae?
Each os coxa is a result of the fusion of three bones: the ilium, ischium, and pubis. These three bones fuse at the deep hemispherical socket, the acetabulum, which receives the femur.
How are the os coxae connected?
The two os coxae are connected anteriorly to each another at the pubic symphysis as a fibrocartilaginous joint; posteriorly, they articulate with the sacrum at the sacroiliac joints, which may be subject to different morphologies.

What coxal bones join each other anteriorly?
In adults, the hip bones, or coxal bones are formed by the fusion of three pairs of bones: the ilium, ischium, and pubis. The pelvis joins together in the anterior of the body at a joint called the pubic symphysis and with the bones of the sacrum at the posterior of the body.
What are the 3 articulations of the os coxae?
Os Coxa. The os coxa is comprised of three parts : the ilium, ischium, and pubis. These three portions meet in the acetabulum, the laterally oriented depression for the femoral head.
What bones make up the os coxae?
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.
Which two bones of the os coxa are held together by fibrocartilage at the front of the pelvic girdle?
Body of the pubis: anterior and superior to the inferior ramus of the pubis. Forms the pubic symphysis with the other os coxa. The two bones are joined by a fibrocartilage to form a cartilaginous symphysis.
Which structure represents the articulation between the right and left coxal bones?
Also, the two coxal bones articulate with one another at the midline of the body at the joint called the pubic symphysis.
