leg and ankle Flashcards
identify upper and lower part extensor reticulum
ass through
perioneal reticulum
tendons 2 perinoeal muscles
flexor retinaculum medial side
what are dorsiflexors
tibialis anterior
what are plantarflexors
gastrocnemius
soleus
plantaris
what is this muscle
tendon passes under extensor retilaculum and wraps around to insert 1st cuniate bone
what is the main action tibialis anterior
dorsiflexion
and inversionensors toes
gastrocneumus
both sides
two heads - medial and lateral condyles femur two heads unite form flat tendon then with soleus to form calcaneul tendon
soleus
arises medial tibia
plataris
lat epicondyl femur unites with calcaneul tendon
calcaneous tendon
infront pad of fat
inserts calcaneus
be aware investing deep fascia
infront of soleus is transverse intermuscular septum
infront soleus
attached fibula
what produces inversion foot
tibialis anterior
tibialis posterior
tibialis posterior
arises back tibia and fibula to behind medial malleolus through flexor retinaculum 1st cuniform bone and bases 2-4 metatarsal
what is the action tibialis posterior
inverts foot
peroneus brevis
distal fibula
peroneus longus
ontop peroneus brevis
deep peroneal nerve passes
tendon peroneus longus and brevis
peroneus brevis passes before longus
longus runs all the way round
peroneus tertius
infront longus and brebis
tendon under flexor retinaculum infront lateral malleolus
what is the action all three peroneal muscles
evert foot
peroneus tertius can also help dorsiflex ankle
