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. [2] Nerve to pectineus - This nerve arises from the femoral nerve just above the inguinal ligament. It passes behind the femoral sheath to reach the anterior surface of the pectineus muscle ...
The pectineus muscle arises from the pectineal line of the pubis and to a slight extent from the surface of bone in front of it, between the iliopectineal eminence and pubic tubercle, and from the fascia covering the anterior surface of the muscle; the fibers pass downward, backward, and lateral, to be inserted into the pectineal line of the femur which leads from the lesser trochanter to the ...
Femoral nerve: Medial compartment (inner thigh/groin) Pectineus, [2] External obturator, Gracilis muscle, Adductors (longus, brevis, and magnus) Obturator nerve: Posterior compartment (back of the thigh) 'hamstring portion' of the Adductor magnus, Biceps femoris, Semitendinosus and Semimembranosus: Sciatic nerve
The intermediate cutaneous nerve (middle cutaneous nerve) pierces the fascia lata (and generally the sartorius) about 7.5 cm below the inguinal ligament, and divides into two branches which descend in immediate proximity along the forepart of the thigh, to supply the skin as low as the front of the knee.
Spatially, it is in this location, but functionally, it is more similar to the other lateral rotator group muscles). The pectineus is sometimes included in this group, [1] [3] and sometimes excluded. [2] [4] It has the same function as the others in this group, but different innervation – namely, the femoral nerve.
The hamstrings are innervated by the sciatic nerve, specifically by a main branch of it: the tibial nerve. (The short head of the biceps femoris is innervated by the common fibular nerve). The sciatic nerve runs along the longitudinal axis of the compartment, giving the cited terminal branches close to the superior angle of the popliteal fossa.
It can cause pain in the low or mid back, SI joint, hip, groin, thigh, knee, or any combination. The iliopsoas gets innervation from the L2-4 nerve roots of the lumbar plexus which also send branches to the superficial lumbar muscles. The femoral nerve passes through the muscle and innervates the quadriceps, pectineus, and sartorius muscles. It ...
The nerve of the anterior compartment of thigh is the femoral nerve. [2] Innervation for the quadriceps muscles come from the posterior division of the femoral nerve, while the anterior division (which contains cutaneous as well as muscular components) gives a lateral and a medial branch, the second being responsible for the innervation of the sartorius muscle.
