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. [1]
However, human feet, and the human medial longitudinal arch, differ in that the anterior part of the foot is medially twisted on the posterior part of the foot, [12] so that all the toes may contact the ground at the same time, and the twisting is so marked that the most medial toe, the big toe or hallux, (in some individuals the second toe ...
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.
Lower limb. Foot. 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.
The medial cuneiform (also known as first cuneiform) is the largest of the cuneiforms. It is situated at the medial side of the foot, anterior to the navicular bone and posterior to the base of the first metatarsal. Lateral to it is the intermediate cuneiform.
The dorsal ligaments are three small bundles, one attached to each of the cuneiform bones. The bundle connecting the navicular with the medial cuneiform bone is continuous around the medial side of the articulation with the plantar ligament which unites these two bones.
The dorsal talonavicular ligament is a broad, thin band, which connects the neck of the talus to the dorsal surface of the navicular bone; it is covered by the Extensor tendons. The plantar calcaneonavicular supplies the place of a plantar ligament for this joint.
