Answer 6

superficial fibular nerve

l5, s1

Question 7

fibularis brevis actions

Answer 7

plantar flex foot at talocrural joint

evert foot at subtler joint

Question 8

common fibular nerve path

Answer 8

goes around head of fibula into lateral leg compartment

superfical fibular nerve-innervation of lateral compartment

deep fibular nerve-passes through anterior crural intermusclar septum to innervate muscles of anterior compartment of leg

Question 9

where does superficial fibular nerve come from and what does it do

Answer 9

from common fibular nerve

innervates lateral compartment

Question 10

where does deep fibular nerve come from and what does it do

Answer 10

from common fibular nerve

travels to anterior side of leg to innervate muscles there
