重點提要:跟骨神經分支:

Tibial and rural n支配腳跟皮膚
Anterior compartment 有4條主要肌肉:

神經:deep tubular nerve(common tubular n分支

1.脛前肌tibialis anterior :  dorsiflex ankle +invert foot 

a.tibia +骨間膜-->cuneiform +1st metatarsaal base 

2.伸趾長肌extensor digitorum longus :dorsiflex ankle+extend lateral 4 digits

a,tibia +fibula +骨間膜-->middle and distal 4 phalanges  

3.伸拇長肌extensor hallucis  longus :dorsiflex ankle +extend great toe 

a.fibular + 骨間膜-->great toe 

4.第三腓骨肌fibularis tertius :weakly plantarflexs  ankle +everts  foot  

a.fibula+ 骨間膜->5th metatarsal 
lateral  compartment 有2條主要肌肉:

神經:superficial tubular nerve(common tubular n 分支)

1.fibularis longus 腓骨長肌:plantarflex ankle +evert foot
a.fibula ->1st metatarsal 
2.fibularis brevis  腓骨短肌:plantarflex ankle +evert foot
a.fibula ->5th metatarsal 

posterior compartment of leg (淺層3 條+深層4條)

神經:tibial nerve(from sciatic nerve)

淺層:

1.腓腸肌gastrocnemius :

a.plantarflex  ankle ( 當膝蓋伸直時)

b.提起腳跟(走路時)

c.屈曲小腿

d.起始--終止

(側)femur lateral condyle ->calcaneal tendon (calcaneus) 

(中)femur popliteal surface (medial condyle 上方)   

2.比目魚肌soleus :platarflex ankle

a.起始--終止fibula and tibia ->calcaneal tendon (calcaneus)



3.蹠肌plantaris :協助腓腸肌(gastrocnemius ) platarflex ankle 

a.起始--終止lateral  supraconylarline of femur  ->calcaneal tendon (calcaneus)


深層:(繞過足踝內後方)1.popliteus :flex knee+medially rotate tibia 

lateral condyle of femur ->posterior surface of fibular 

2.flexor hallucis longus :plantarflexor ankle+flex great toe 

a.下2/3 fibula 後側+骨間膜--> distal phalanx of great toe  (base )

3.flexor digitorum longus :plantarflexor ankle +flex lateral 4 digits 

a. 後中側tibia -->distal phalanx of 4 digits   (base )

4.tibialis posterior:plantarflex ankle +invert foot 

a.骨間膜+tibia +fibula-->navicular +cuboid +calcaneus +base of 234 metatarsals
