Practical 06 - Posterior Leg ; Tarsal Tunnel ; Osteology of Foot Flashcards
the posterior compartment is divided into 2 groups the gastronemius and the soleus make up which group
a.superficial
b.deep
a.superficial
gastronemius has 2 heads and a strong tendon (calcaneal tendon)- crosses 2 joints , flexes at knee , flex at ankle joint (plantarflex)
tibialis posterior, flexor hallucis longus and flexor digitorum longus make up whic compartment of the leg
a.superficial
b.deep
b.deep
the soleus muscle is
a.lateral
b.medial
a.lateral
when the knee joint is extended and locked in weight bearing which muscle is responsible for unlocking the joint
a.gastrocnemius
b.soleus
c.popliteus
c.popliteus
innervated by tibial nerve
which muscle is immediately deep to the gastrocnemius muscle
a.soleus
b.flexor hallucis longus
c.flexor hallucis longus
d.tibialis posterior
a.soleus
doesnt cross knee joint so no action at knee
what does the soleus muscle join onto in order to planta flex (v powerful)
a.calcaneous
b.calcaneal tendon
c.gastrocnemius
d.fibula
b.calcaneal tendon
innervated by tibial nerve
all posterior compartment innervated by
tibial nerve
most medial of the deep muscles
a.flexor digitorum longus
b.flexor hallucis longus
c.tibialis posterior
a.flexor digitorum longus
most lateral of the deep muscles
a.flexor digitorum longus
b.flexor hallucis longus
c.tibialis posterior
b.flexor hallucis longus
what is the function of tibialis posterior
a.invert the foot
b.evert the foot
c.dorsiflexion
d.plantarflexion
a.invert the foot at sub talar joint
tibial nerve innervates
all posterior compartment of leg
posterior tibial aa
prvides blood to all posterior muscles
vena connitantes
drain deep structures
