#Thigh compartments free#

The semimembranosus is named for the flat shape of its superior attachment.The arteries of the posterior compartment of the thigh arise from the inferior gluteal and the perforating branches of the profunda femoris. The semitendinosus is named for its unusually long tendon. The hamstrings flex the knee, and aided by the gluteus maximus, they extend the hip during walking and running. The tendons of the above muscles can be felt as prominent cords on both sides of the fossa-the biceps tendon on the lateral side and the semimembranosus and semitendinosus tendons on the medial side. A rare case is presented of acute anterior compartment syndrome in the thigh of a footballer caused by an acute quadriceps strain, exacerbated by poor first.
The pit at the back of the knee, known anatomically as the popliteal fossa, is colloquially called the ham. The short head of the biceps femoris is innervated by the fibular nerve. These muscles are mainly innervated by the sciatic nerve, specifically the tibial nerve. The muscles here (except for the short head of the biceps femoris) are the hamstrings. The obturator artery is the blood supply to the medial thigh. The obturator nerve is the primary nerve supplying this compartment.
The posterior fascial compartment of the thigh contains the knee flexors and hip extensors. The medial compartment of thigh is one of the fascial compartments of the thigh and contains the hip adductor muscles and the gracilis muscle.
