The small pit on the head of the femur for a ligament.

• A. Scapular notch
• B. Fovea for ligament of head of femur
• C. Facet for plantar calcaneonavicular ligament
• D. Coracoid process

Answer: (B)

The small pit on the head of the femur is the fovea capitis femoris, which serves as the attachment site for the ligamentum teres femoris (the ligament of the head of the femur). This ligament runs from the acetabular fossa to the fovea on the femoral head and helps stabilize the hip joint, also carrying a small artery to the head of the femur. The other structures mentioned are not on the femoral head: the scapular notch is on the scapula, the plantar calcaneonavicular facet is on the calcaneus, and the coracoid process is also a scapular projection.
