Final answer:
The major bones in the lower limb include the femur in the thigh, the tibia and fibula in the leg, and seven tarsals, five metatarsals, and fourteen phalanges in the foot and toes. The hip joint is a weight-bearing ball-and-socket joint formed by the femoral head and the acetabulum. The shoulder includes the scapula and clavicle, which contribute to its range of motion.
Step-by-step explanation:
The student is asking about the different regions of the lower limb and the skeletal anatomy of various parts of the body. The lower limb is divided into three regions: the thigh, the leg, and the foot. The thigh contains the single bone called the femur. The leg has two bones, the tibia, which is the weight-bearing bone on the medial side, and the fibula, the thinner bone on the lateral side.
The ankle has seven tarsal bones that are part of the foot's structure, which also includes five metatarsals and fourteen phalanges. The hip joint is a ball-and-socket joint consisting of the femoral head and the acetabulum of the hip bone. Bony landmarks help form this stable and strong joint needed for weight-bearing tasks such as standing and walking. The shoulders are part of the upper body and are made of the scapula and clavicle, which allow for upper limb mobility.
