Innervations of the Foot Flashcards
sciatic nerve divides into?
common fibular nerve
tibial nerve
common fibular nerve divides into?
deep fibular n.
superficial fibular n.
sural nerve is formed by?
communicating ramus from lateral sural cutaneous nerve + medial sural cutaneous nerve (which is a branch of the tibial n.)
deep fibular n. is a branch of?
common fibular n
deep fibular n. innervates what compartment?
anterior leg
deep fibular n. courses
deep to the deep fascia with the anterior tibial vessels
on the dorsum of the foot, the deep fibular divides into
medial and lateral terminal branch
medial terminal branch follows the course of
the dorsal pedis a.
medial terminal branch becomes superficial
as it pierces the deep fascia at the proximal aspect of the 1st interspace
medial terminal branch divides into
2 dorsal proper digital n. for the adjacent sides of the hallux and 2nd toe
lateral terminal branch follows the course of
the lateral tarsal a
lateral terminal branch innervates what muscles
EHB
EDB
superficial fibular n is a branch of
common fibular n
superficial fibular n. innervates what compartment
lateral leg compartment
superficial fibular n. pierces the deep fascia in the —of the leg
lower 1/3
superficial fibular n. innervates —after it pierces the deep fascia
skin on the lower anterolateral aspect of the leg
—to the malleoli the superficial fibular n. divides into —- and —-
Proximal
medial dorsal cutaneous n.
intermediate dorsal cutaneous n
medial dorsal cutaneous n. is a branch of
superficial fibular n. in the lower leg
on the dorsum of the foot, the medial dorsal cutaneous n. divides into
dorsal proper digital br.
dorsal common digital br.
the dorsal proper digital br of the medial dorsal cutaneous n. innervates
the skin on the dorsomedial aspect of the hallux
the dorsal proper digital branch of the medial dorsal cutaneous n. communicates with
the medial terminal branch of the deep fibular n. and the saphenous n
the dorsal common digital branch of the medial dorsal cutaneous n. divides into
2 dorsal proper digital branches for the skin on the adjacent sides of the 2nd and 3rd toes
medial dorsal cutaneous nerve innervates
the skin on the dorsomedial side of the foot
intermediate dorsal cutaneous nerve also called?
Lemont’s nerve
intermediate dorsal cutaneous nerve branches from
the superficial fibular nerve in the lower leg region
intermediate dorsal cutaneous nerve divides into — and — on the dorsum of the foot
medial dorsal common digital branch
lateral dorsal common digital branch
medial dorsal common digital branch of the intermediate dorsal cutaneous nerve divides into
2 dorsal proper digital branches for the sin on the adjacent sides of the 3rd and 4th toes
lateral dorsal common digital branch of the intermediate dorsal cutaneous nerve divides into
2 dorsal proper digital branches for the skin on the adjacent sides of the 4th and 5th toes
lateral dorsal common digital br. of the intermediate dorsal cutaneous n. communicates with
the lateral dorsal cutaneous nerve
the intermediate dorsal cutaneous n. innervates
the skin on the dorsointermediate side of the foot
