14. The head of the femur articulates with the acetabulum of the pelvic girdle. The femur and the pelvic girdle are involved in walking.
Acetabulum is a deep, hemispherical, cup shaped depression that articulates with the head of the femur. Acetabulum is formed by the pubis, ischium, and ilium of the pelvic girdle. The ball shape of acetabulum allows it to roll the femur. Hence, the femur is rotated in a manner to facilitate walking.
Option is acetabulum.
15. The proximal end of the tibia articulates with the medial and lateral condyles of the femur at the distal end. The proximal end of the tibia is widened into a medial and lateral condyles.
Option is medial, lateral, medial condyle, lateral condyle.
At the distal end, the medial and lateral condyles of the femur articulate with medial condyle and lateral condyle of tibia.
16. The proximal end of the fibula is expanded in to a head that articulates just inferior to the lateral condyle of the tibia.
Option is Lateral tibial condyle.
17. The calcaneus is known as the heel bone. It is a large bone, which connects the talus and cuboid bones to form the subtalar joint. It is one of the largest tarsal bones and lies at the back of the foot.
Option is calcaneus.
