Features of Individual Bone - Lower Limb

Features of Individual Bone of lower limb: strongest bones of the body.

Bones are namely-

Femur or thigh bone , is the single bone of the thigh region . It is the longest and strongest bone of the body, and accounts for approximately one-quarter of a person’s total height. The rounded, proximal end is the head of the femur , which articulates with the acetabulum cavity of the hip bone to form the hip joi nt.

Patella (kneecap) is the largest sesamoid bone of the body. A sesamoid bone is a bone that is incorporated into the tendon of a muscle where that tendon crosses a joint. The sesamoid bone articulates with the underlying bones to prevent damage to the muscle tendon due to rubbing against the bones during movements of the joint.

Tibia (shin bone) is the medial bone of the leg and is larger than the fibula, with which it is paired. The tibia is the main weight-bearing bone of the lower leg and the second longest bone of the body, after the femur. The medial side of the tibia is located immediately under the skin, allowing it to be easily palpated down the entire length of the medial leg.

Fibula is the slender bone located on the lateral side of the leg . The fibula does not bear weight. It serves primarily for muscle attachments and thus is largely surrounded by muscles. Only the proximal and distal ends of the fibula can be palpated Seven Tarsal bones form the posterior half of foot. The most superior bone is the talus . This has a relatively square-shaped, upper surface that articulates with the tibia and fibula to form the ankle joint.

Five metatarsal  bones which are located between the tarsal bones of the foot and the phalanges of the toes  These elongated bones are numbered 1–5, starting with the medial side of the foot. The first metatarsal bone is shorter and thicker than the others. The second metatarsal is the longest. The base of the metatarsal bone is the proximal end of each metatarsal bone.
