Each digital branch give off a dorsal branch to supply the nail beds on the dorsum. This nerve also gives off articular branches to supply the bones of the tarsus and metatarsus. [1] Lateral plantar nerve - It is the smaller terminal branch of the tibial nerve. It courses laterally and forward until the base of fifth metatarsal bone, where it ...
The medial calcaneal branches of the tibial nerve (internal calcaneal branches) perforate the laciniate ligament, and supply the skin of the heel and medial side of the sole of the foot. [ 1 ] Structure
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.
Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus
The muscular branches supply muscles on the medial side of the sole, including the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis, and the first lumbrical; those for the abductor hallucis and flexor digitorum brevis arise from the trunk of the nerve near its origin and enter the deep surfaces of the muscles; the branch of the flexor hallucis brevis springs from the ...
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 ...

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.
