Green is the medial compartment (gracilis and adductor magnus), blue is the posterior (semimembrosus to biceps c. brevis) and red is the anterior (vastus lateralis to sartorius). The fascial compartments of thigh are the three fascial compartments that divide and contain the thigh muscles .
The anterior compartment is one of the fascial compartments of the thigh that contains groups of muscles together with their nerves and blood supply. The anterior compartment contains the sartorius muscle (the longest muscle in the body) and the quadriceps femoris group, which consists of the rectus femoris muscle and the three vasti muscles – the vastus lateralis, vastus intermedius, and ...
The rectus femoris is situated in the middle of the front of the thigh; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight (Latin: rectus) down to the deep aponeurosis. Its functions are to flex the thigh at the hip joint and to extend the leg at the knee joint. [1]
Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles: Tensor fasciae latae; Medial compartment of thigh. Pectineus; Adductor longus; Adductor brevis; Gracilis; Without the iliopsoas muscles, flexion in sitting position is not possible across the horizontal plane. [2]
In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4 cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery. The branches are shown below: [1]
The muscles of the posterior compartment of the thigh are the: [2] [3] biceps femoris muscle, which consists of a short head and a long head. semitendinosus muscle; semimembranosus muscle; These muscles (or their tendons) apart from the short head of the biceps femoris, are commonly known as the hamstrings.
The vastus lateralis is the largest and most powerful of the three vasti muscles. It arises from the several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.
In anatomy, the thigh is the area between the hip and the knee.Anatomically, it is part of the lower limb. [1]The single bone in the thigh is called the femur.This bone is very thick and strong (due to the high proportion of bone tissue), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee.
