Dorsal digital nerves of foot
Encyclopedia
Dorsal digital nerves of foot are branches of the intermediate dorsal cutaneous nerve
, medial dorsal cutaneous nerve
, sural nerve
and deep fibular nerve
. There are 10 total dorsal digital branches.
- The medial terminal branch (internal branch) divides into two dorsal digital nerves (nn. digitales dorsales hallucis lateralis et digiti secundi medialis) which supply the adjacent sides of the great and second toes,
- The medial dorsal cutaneous nerve (internal dorsal cutaneous branch) passes in front of the ankle-joint, and divides into three dorsal digital branches, one of which supplies the medial side of the great toe, the other, the adjacent sides of the second and third toes.
- 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.
Intermediate dorsal cutaneous nerve
The intermediate dorsal cutaneous nerve , the smaller, passes along the lateral part of the dorsum of the foot, and divides into dorsal digital branches, which supply the contiguous sides of the third and fourth, and of the fourth and fifth toes.It also supplies the skin of the lateral side of the...
, medial dorsal cutaneous nerve
Medial dorsal cutaneous nerve
The medial dorsal cutaneous nerve passes in front of the ankle-joint, and divides into two dorsal digital branches, one of which supplies the medial side of the great toe, the other, the adjacent side of the second and third toes.It also supplies the integument of the medial side of the foot and...
, sural nerve
Sural nerve
The sural nerve , formed by the junction of the medial sural cutaneous with the peroneal anastomotic branch of the lateral sural cutaneous nerve, passes downward near the lateral margin of the tendo calcaneus, lying close to the small saphenous vein, to the interval between the lateral malleolus...
and deep fibular nerve
Deep fibular nerve
The deep fibular nerve begins at the bifurcation of the common fibular nerve, between the fibula and upper part of the fibularis longus, passes infero-medially, deep to extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior...
