What forms the posterior inferior portion of the hip socket?
ischium
The ischium forms the posterolateral portion of the hip bone (see Figure 2). The large, roughened area of the inferior ischium is the ischial tuberosity. This serves as the attachment for the posterior thigh muscles and also carries the weight of the body when sitting.
Which bone is the most inferior and posterior bone of the hip bone?
The ischium forms the most inferior and posterior portion of the coxal bone; It is the portion of the pelvic girdle that supports the body when seated and it is commonly known as the “sits bone”.
What is the inferior portion of the pelvis?
The inferior limit of the lesser pelvic cavity is called the pelvic outlet. This large opening is defined by the inferior margin of the pubic symphysis anteriorly, and the ischiopubic ramus, the ischial tuberosity, the sacrotuberous ligament, and the inferior tip of the coccyx posteriorly.
What is the most inferior posterior bone in the body?

Ischium: Roughly arc-shaped bone; forms the most inferior and posterior portion of the os coxa.
What is the hip socket called?
The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint.
What bones make up each hip bone?
The hip bone is formed by three parts: the ilium, ischium, and pubis. At birth, these three components are separated by hyaline cartilage. They join each other in a Y-shaped portion of cartilage in the acetabulum.

What is a pubic bone?
The pubis, also known as the pubic bone, is located in front of the pelvic girdle. These bones are located almost directly above the hip bone and are often visible in women and individuals with little body fat. The pubic bone is not visible outside of the body and joins the front-facing half of the pelvic girdle.
What part of the hip bone is most anterior?

When you place your hands on your waist, you can feel the arching, superior margin of the ilium along your waistline (see [link] ).
