The anterior cutaneous branches of the femoral nerve consist of the following nerves: intermediate cutaneous nerve and medial cutaneous nerve. Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... The Femoral Nerve supplies innervation the anterior portion of the leg. ...

Intermediate cutaneous 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. For the muscle, see sartorius muscle. ... The inguinal ligament is a band running from the pubic tubercle to the anterior superior iliac spine. ... Diagram of the human thigh bone In humans the thigh is the area between the pelvis and buttocks and the knee. ...


Here they communicate with the medial cutaneous nerve and the infrapatellar branch of the saphenous, to form the patellar plexus. The terminal filaments of the lateral femoral cutaneous nerve frequently communicate with the anterior cutaneous branches of the femoral nerve, and with the infrapatellar branch of the saphenous nerve, forming with them the patellar plexus. ...


In the upper part of the thigh the lateral branch of the intermediate cutaneous communicates with the lumboinguinal branch of the genitofemoral nerve. In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. ...


Medial cutaneous nerve

The medial cutaneous nerve (internal cutaneous nerve) passes obliquely across the upper part of the sheath of the femoral artery, and divides in front, or at the medial side of that vessel, into two branches, an anterior and a posterior. Femoral artery and its major branches - right thigh, anterior view. ...


The anterior branch runs downward on the Sartorius, perforates the fascia lata at the lower third of the thigh, and divides into two branches: one supplies the integument as low down as the medial side of the knee; the other crosses to the lateral side of the patella, communicating in its course with the infrapatellar branch of the saphenous nerve. For the muscle, see sartorius muscle. ... The Saphenous Nerve (long or internal saphenous nerve) is the largest cutaneous branch of the femoral nerve. ...


The posterior branch descends along the medial border of the Sartorius muscle to the knee, where it pierces the fascia lata, communicates with the saphenous nerve, and gives off several cutaneous branches. Grays FIG. 430– Muscles of the iliac and anterior femoral regions. ... The deep fascia of the thigh is named, from its great extent, the fascia lata; it constitutes an investment for the whole of this region of the limb, but varies in thickness in different parts. ...


It then passes down to supply the integument of the medial side of the leg.


Beneath the fascia lata, at the lower border of the Adductor longus, it joins to form a plexiform net-work (subsartorial plexus) with branches of the saphenous and obturator nerves. The Adductor longus muscle is a muscle of the human body. ...


When the communicating branch from the obturator nerve is large and continued to the integument of the leg, the posterior branch of the medial cutaneous is small, and terminates in the plexus, occasionally giving off a few cutaneous filaments. The Obturator Nerve arises from the ventral divisions of the second, third, and fourth lumbar nerves; the branch from the third is the largest, while that from the second is often very small. ...


The medial cutaneous nerve, before dividing, gives off a few filaments, which pierce the fascia lata, to supply the integument of the medial side of the thigh, accompanying the long saphenous vein.


One of these filaments passes through the saphenous opening; a second becomes subcutaneous about the middle of the thigh; a third pierces the fascia at its lower third.
