Compartment Muscles Neurovascular structures Anterior compartment (front of the thigh) Sartorius muscle, Quadriceps (Rectus femoris, Vastus lateralis, Vastus intermedius and Vastus medialis), Articularis genus: Femoral nerve: Medial compartment (inner thigh/groin) Pectineus, [2] External obturator, Gracilis muscle, Adductors (longus, brevis ...
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 Thomas Test examines the iliopsoas, the group of muscles that connects the spine to your legs, through the pelvis; the rectus femoris, the quad muscles that run from your hip to your knee; and ...
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 iliopsoas is the prime mover of hip flexion, and is the strongest of the hip flexors (others are rectus femoris, sartorius, and tensor fasciae latae). [3] The iliopsoas is important for standing, walking, and running. [2] The iliacus and psoas major perform different actions when postural changes occur.
