pelvis and hip bone

coxal

One of the two hip bones that form the sides of the pelvis. Each coxal bone consists of the ilium, ischium, and pubis.

ilium

The broad, flaring upper portion of the coxal bone. Its upper border forms the iliac crest.

pubis

The anterior portion of the coxal bone. The left and right pubic bones meet at the pubic symphysis.

ischium

The lower, posterior portion of the coxal bone. It bears much of your weight when you sit.

pubic arch

The arch-shaped angle beneath the pubic symphysis, formed by the left and right inferior pubic rami.

ischial tuberosity

The roughened, rounded part of the ischium that you sit on.

obturator foramen

The large opening formed by the pubis and ischium on each side of the pelvis.

pubic crest

The short ridge along the upper border of the pubis, near the midline.

pubic symphysis

The fibrocartilage joint where the left and right pubic bones meet at the front of the pelvis.

acetabulum

The deep, cup-shaped socket on the lateral side of the coxal bone where the head of the femur fits to form the hip joint.
