Muscle Origin Insertion Innervation Main Action Fibularis longus: Head and superior two thirds of lateral surface of fibula: Base of 1st metatarsal and medial cuneiform: Superficial fibular nerve (L5, S1, S2) Everts foot and weakly plantarflexes ankle Fibularis brevis: Inferior two thirds of lateral surface of fibula
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 .
Blood vessels and nerves can also be affected by the pressure caused by any swelling in the leg. If the pressure becomes great enough, blood flow to the muscle can be blocked, leading to a condition known as compartment syndrome. Severe damage to the nerve and blood vessels around a muscle can cause the muscle to die and amputation might be ...
Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.

There are several ways of classifying the muscles of the hip: By location or innervation (ventral and dorsal divisions of the plexus layer); By development on the basis of their points of insertion (a posterior group in two layers and an anterior group); and; By function (i.e. extensors, flexors, adductors, and abductors).

At the medial lemniscus, axons from the leg are more ventral, and axons from the arm are more dorsal. Fibres from the trigeminal nerve (supplying the head) come in dorsal to the arm fibres, and travel up the lemniscus too. The medial lemniscus rotates 90 degrees at the pons. The secondary axons from neurons giving sensation to the head, stay at ...
