Acetabular cavity (Acetabulum, Cotyloid Cavity)

The Acetabular Cavity (lat. Acetabulum, English Cotyloid Cavity) is a cup-shaped depression on the outer surface of the pelvic bone, forming the hip joint together with the head of the femur.

This depression has a semilunar shape and is directed outward, posteriorly and downward. Its anterior and lower parts are formed by the fused branches of the pubic and ischial bones, and the posterior and upper parts are formed by the ilium.

The acetabulum is lined with cartilage, which ensures smooth gliding and freedom of movement of the femoral head in the hip joint. The cartilaginous lip along the edge of the cavity deepens it and increases the area of ​​contact with the femoral head.

In general, the acetabulum plays an important role in the formation of a mobile hip joint, providing a strong connection of the pelvic girdle with the lower limb and the possibility of various movements of the leg.



The acetabulum is a cup-shaped depression located on the outer surface of the pelvic bone and forms the hip joint with the head of the femur. This socket is one of the most important elements of the hip joint, as it provides stability and mobility.

The acetabulum is shaped like a bowl and is located on the side of the pelvis. It is formed by the acetabulum and the acetabular margin. The acetabulum is a depression that serves to accommodate the head of the femur, which fits into it during movement.

The acetabulum is very important for the stability of the hip joint. It allows the head of the femur to move within its socket, which allows the hip joint to move freely and protects it from damage.

In addition, the socket in the acetabulum also plays a role in the formation of the hip joint. The acetabulum and the acetabulum together form the hip joint, which allows the hip to move in different directions.

Thus, the acetabulum is a very important element of the hip joint, which ensures its stability, mobility and formation. Its proper functioning is key to human health and well-being.
