Flashcards in test 4 anterior/lateral leg Deck (26):
1

Tibialis anterior (TA) origin

Lateral condyle and superior half of lateral surface of tibia and interosseous membrane

2

Tibialis anterior (TA) insertion

Medial and inferior surfaces of medial cuneiform and base of 1st metatarsal

3

Tibialis anterior (TA) innervation

Deep fibular nerve (L4, L5)

4

Tibialis anterior (TA) action

Dorsiflexes ankle; inverts foot; supports medial longitudinal arch of foot

5

Extensor hallucis longus (EHL) origin

Middle part of anterior surface of fibula and interosseous membrane

6

Extensor hallucis longus (EHL) insertion

Dorsal aspect of base of distal phalanx of great toe (hallux)

7

Extensor hallucis longus (EHL) innervation

Deep fibular nerve (L5, S1)

8

Extensor hallucis longus (EHL) action

Extends great toe; dorsiflexes ankle

9

11

Extensor digitorum longus (EDL) innervation

Deep fibular nerve (L5, S1)

12

Extensor digitorum longus (EDL) action

Extends lateral four digits; dorsiflexes ankle

13

Fibularis tertius origin

Inferior third of anterior surface of fibula and interosseous membrane

14
