What structures form the hip joint?

The hip joint is a ball-and-socket joint that allows for a wide range of movement and weight-bearing support. The key structures that form the hip joint are the acetabulum and the femoral head. The acetabulum is a cup-shaped socket located on the pelvis, specifically where the three pelvic bones (ilium, ischium, and pubis) fuse together, and it receives the head of the femur, which is the rounded top of the femur bone.

This connection enables the hip joint to facilitate a significant degree of mobility, including flexion, extension, abduction, adduction, and rotation, while also providing stability. The arrangement of the acetabulum and femoral head creates a deep socket that securely holds the femur in place, allowing for the necessary strength and range of motion required for activities such as walking, running, and jumping.

The other answer choices involve structures that are related to the hip but do not accurately describe the primary components of the hip joint itself. The pelvis and femur combination is too broad, as it does not specify the exact interaction at the joint. The pubis and ischium are parts of the pelvis but do not connect directly at the joint.
