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)
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
