Anterior leg and dorsum of the foot Flashcards
What is the superficial vein of the medial side of the anterior leg
great saphenous vein
Where does the great saphenous vein originate
starts at the dorsal venous arch of the foot
Where does the great saphenous vein run
then passes anterior through the medial malleolus and goes within the superficial fascia up the leg
How does the great saphenous vein end
drains into the femoral nerve
Which nerve travels with the great saphenous vein
the saphenous nerve - cutaneous nerve from the femoral nerve
What does the saphenous nerve supply
It supplies the skin on the medial side of the leg and goes to the medial side of the foot
What compartment is the superficial fibular nerve supply
nerve of the lateral compartment
Where does tibialis anterior muscle originate
originates from the upper 2/3 of the lateral tibia
Where does tibialis anterior muscle insert
passes under extensor retinaculum to insert on the medial cuneiform and base first metatarsal bone of the foot
What is the function of tibialis anterior muscle
function is dorsiflexion and inversion of the foot
What is shin splints
A soft tissue injury involving the muscular origin of the tibialis anterior muscle on both bone and periosteum
Where does extensor hallucis longus originate
on the anterior surface of the fibula and the adjacent interosseous membrane
Where does extensor hallucis longus insert
It passes under extensor retinaculum and inserts partly on to the distal phalanx of the big toe and partly on to the extensor expansion of the first MP joint
Extensor hallucis longus function
is extension of big toe and dorsiflexion of foot.
Which muscle is located on top of extensor hallucis longus
extensor digitorum longus
Where in the leg is extensor digitorum longus located
lateral aspect
where does extensor digitorum longus originate
originates on the lateral tibial condyle, proximal ¾ of anterior fibula
Where does extensor digitorum longus insert
It passes under the extensor retinaculum, when it goes to the dorsum of the foot it splits into 4 tendons, going to digits 2-5, inserting onto the middle and distal phalanges.
What is the function of extensor digitorum longus
is extension of toes 2-5 (MP joint) and dorsiflexion of the ankle.
Where does peroneus tertius originate
originates with extensor digitorum longus from the medial fibular shaft
Where does the peroneus tertius insert
followed down to the dorsum of the foot its tendon attaches to the baseof the 5th metatarsal
What is the function of peroneus tertius
function is to assist extensor digitorum longus in dorsiflexion and has a role in eversion and abduction of the foot.
What is the muscle of the dorsum of the foot
extensor digitorum brevis
Where does extensor digitorum brevis originate
on the dorsal surface of the calcaneus
