1

What's the action of the tibialis anterior?

Dorsiflexing and inversion of the foot

2

What's the origin and insertion of the tibialis anterior?

O - Lateral tibial condyl
- upper lateral surface of tibia
I - medial cuneiform and first metatarsal bones of the foot

3

what is the arterial and nerve supply of the tibialis anterior?

anterior tibial artery and deep fibular (peroneal) nerve

4

what's the action of the extensor digitorum longus?

extension of toes and dorsiflexion of the ankle

5

what's the origin and insertion of the extensor digitorum longus?

O - anterior lateral condyl of tibia and anterior shaft of fibular and superior 3/4 of interosseous memb.
I - dorsal surface of the middle and distal phalanges of the lateral 4 digits.

6

what's the arterial and nerve supple of the extensor digitorum longus?

anterior tibial artery and deep fibular nerve

7

what's the action of the extensor hallicus longus?

extends the hallux and also assists in dorsiflexion of the foot and ankle.

8

what's the origin and insertion of the extensor hallicus longus?

O - middle portion of fibular on the anterior surface and the interosseous membrane.
I - dorsal side of base of the distal phalanx.

9

what's the artery and nerve supply to the extensor hallicus longus?

deep tibial artery and deep fibular nerve

10

what's the action of the peroneus (fibularis) longus?

plantarflexion, eversion and support arches.

11

what's the origin and insertion of the peroneus (fibular) longus?

O - upper lateral shaft of fibular
I - first metatarsal bones of foot and medial cuneiform.

12

what's the artery and nerve supply to the peroneus (fibularis) longus?

fibular (peroneal) artery and superficial fibular (peroneal) nerve.

13

what's the action of the peroneus (Fibularis) brevis?

plantar flexion and eversion

14

what's the origin and insertion of the peroneus (fibularis) brevis?

O - lower two thirds of the lateral fibula
I - 5th metatarsal

15

what's the artery and nerve supply to the peroneus (fibularis) brevis?

fibular artery and superficial fibular nerve

16

what's the action of the peroneus (Fibularis) tertius?

dorsiflexion and eversion

17

what's the origin and insertion of the peroneus tertius?

O - distal surface of the fibula and interosseous membrane
I - dorsal surface of metatarsal 5

18

what's the artery and nerve supply to the peroneus tertius?

the anterior tibial artery and the deep fibular nerve.
