GA 5 posterior leg Flashcards
What are the dynamic supports for the foot arch?
What makes up the passive support for the foot arch?
What do structures in the same compartments share?
Posterior compartment is divided into what?
What muscles are in each compartment?
What vessels are in the posterior compartment?
Gastrocnemius
a small bone associated w/ the calf muscles?
what can damage this?
Soleus
the soleus and gastrocnemius create what?
triceps surae (two heads of gasrtoc and soleus)
Plantaris
Clinical significance of the plantaris?
Popliteus
Deep posterior crural compartment
Arteries in popliteal fossa in relation to posterior muscles?
Flexor hallucis longus
- Largest deep posterior muscle
- lies deep to soleus
- superior attachment
- inferior 2/3 of posterior fibula
- passes inferiorly deep to flexor retinaculum
Largest bone in foot.
what does it articulate with?
important land mark on it?
Flexor digitorum longus
- Deep to soleus
- superior attachment
- posterior tibia inferior to soleal line
- tendon passes posterior to tibalis posterior
Tibialis posterior
- Deepest posterior crural muscle
- same plane as bones
- between f.dl and f.h.l.
- proximal attachment
- interosseous membrane
- posterior tibia inferior to soleal line
- posteromedial surface of fibula
Foot bone tibialis posterior attaches on?
What is the order of vessels and ligaments in the medial ankle?
What innervates the posterior compartment?
Where does it pass?
and where does it leave the posterior compartment?
Tibial n. supplies all posterior compartment muscles
What is the blood supply for the posterior compartment?
Fibular artery?
Clinical posterior tibial artery palpating
Clinical posterior tibial pulse
