Flashcards in Anterior Compartment of the Leg Deck (17):
1

crural fascia

deep fascia in leg

thicker anteriorly

2

what do all muscles of anterior leg have in common 2

they are all ankle dorsiflexors and digit extensors

all innervated by deep fibular nerve l4/5

3

tibialis anterior attachments/innervation

upper two thirds of lateral surface of tibia
interosseus membrane
highest part of superficial crural fascia

medial and planter surface of medial cuneiform bone
and medial base of first metatarsal

deep fibular l4/5

4

tibialis anterior actions

dorsofielx foot at talocrurual point

invert foot at subtalar joint

5

extensor hallucis longusattachments/innervation

middle third of medial surface of fibula
interosseous membrane

dorsal aponeurosis
base of distal phalanx of first toe

deep fibular l5 only

6

extensor hallucis longus actions

dorsiflex foot at talocrural joint
extend toes at MTP and IP joints

eversion and inversion of foot at subtalar joint-depeding on foot position

7

extensor digitorum longus attachments/innervation

anterior border and head of fibula
lateral condyle of tibia
interosseus membrane

dorsal aponeuroses at base of distal phalanges of 2nd to 5th does

deep fibular
l5-s1

8

extensor digitorum longus actions

dorsiflex foot at talocrural joint

evert foot at subtler joint

extend 2nd and 5th does at MTP and IP joints

9

fibularis tertius attachments/innervation

anterior border of distal fibula

baseof 5th metatarsal

deep fibular l5/s1

10

fibularis tertius actions

dorsiflex foot at talocrural joint

evert foot at subtalar joint

11

difference between anterior muscles

lateral to medial

fibularis tertius-smallest

extensor digitorum longus-long but under tibias interior

extensor hallucis longus-long and deep to extensor digitorum longs

tibalis anterior-longest and biggest

12

whats deep to tibialis anterior

what do they do

anterior tibial artery

deep fibular nerve-innnervates anterior compartment

superifical fibular nerve-moves into anterior compartment from lateral compartment of leg

13

extensor retinaculum

same thing as in anterior wrist for anterior foot

14

dorsalis pedis artery

continuation of

where

relation to a tendon/nerve

anterior tibial artery

dorm of foot

lateral to extensor hallcis longus tendon

accompanies deep fibular nerve

15

dorsum of foot

top of it lol

16

dorsal interosseous

dorsal of foot kinda...?

17

deep fibular nerve accompanies

accumpanies dorsalis pedis artery
