APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The hamstring portion originates from the ischial tuberosity and inserts onto the adductor tubercle of the femur. The gracilis adducts the thigh flexes the leg, and aids in medial rotation of the leg. The gracilis is the weakest and most medial of the adductor muscles.

Detailed explanation-2: -The biceps femoris muscle, located in the posterior portion of the thigh, is composed of a long head that originates from the ischial tuberosity and a short head that originates at the linea aspera of the femur. The biceps femoris inserts at the lateral head of the fibula.

Detailed explanation-3: -Quadratus femoris, is a flat quadrilateral muscle that originates along the lateral border of the ischial tuberosity. The insertion point is at the intertrochanteric crest of the femur and produces lateral rotation at the hip. The nerve innervations are by the sacral plexus (L4-S1).

Detailed explanation-4: -Semitendinosus – The semitendinosus attaches proximally at the ischial tuberosity.
