Lumboinguinal nerve (green) and Ilioinguinal nerve (purple). In modern texts, these two regions are often considered to be innervated by the genitofemoral nerve. Medial cluneal nerves (pink) - labeled as "post. division of sacral" Inferior cluneal nerves (pink region, not designated with its own section)
The medial dorsal cutaneous nerve (internal dorsal cutaneous branch) is the more medial one of the two terminal branches of the superficial fibular nerve (the other being the intermediate dorsal cutaneous nerve). Through its branches, it provides innervation to parts of the dorsal aspects of the first, second, and third toes.
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 ...
The superficial fibular nerve terminates by bifurcating into the intermediate dorsal cutaneous nerve and the medial dorsal cutaneous nerve immediately after emerging from the deep fascia of leg at the distal two-thirds to three-fourths point of the leg.
The intermediate dorsal cutaneous nerve divides into four dorsal digital branches, which supply the medial and lateral sides of the third and fourth, and of the fourth and fifth toes. The lateral dorsal cutaneous nerve from the sural nerve turns into a dorsal digital nerve and supplies the lateral side of the fifth toe.
