Hip bone
Hip Bone
The Hip Bone (pronounced: /hɪp boʊn/), also known as the os coxae or innominate bone, is a large, flat bone that forms one of the primary components of the pelvis. It is one of the most important bones in the human body, playing a crucial role in supporting the body's weight and facilitating movement.
Etymology
The term "hip bone" is derived from the Old English word "hipe" or "hippa," which means "hip" or "haunch." The Latin term "os coxae" translates to "bone of the hip" or "hip bone."
Structure
The hip bone is made up of three parts: the ilium, the ischium, and the pubis. These three bones fuse together during adolescence to form a single, solid bone. The point where these three bones meet is called the acetabulum, which serves as the socket for the femur (thigh bone) to form the hip joint.
Function
The primary function of the hip bone is to support the weight of the body in both static (e.g., standing) and dynamic (e.g., walking or running) postures. It also serves as a connection point for several muscles, including the gluteal muscles, iliopsoas, and adductor muscles.
