lab exam2 Flashcards
what nerves run with superficial plantar digital arteries
proper plantar digital nerve
what does the calcaneometatarsal ligament attach to?
base of 5th metatarsal
superficial tibial artery is usually very small, but when is it often larger?
when replacing the 1st plantar metatarsal artery
where is the the superficial plantar arch located between
lies between 1st and 2nd layer
what covers the entrance of vessels and nerves into plantar foot
abductor hallucis
what is the orientations between the medial plantar artery and medial plantar nerve
medial plantar artery lies medial to the nerve
what supplies the 1st lumbrical
1st common plantar digital nerve
what pierces through the flexor retinaculum?
medial calcaneal nerve and artery
when does the peroneus brevis and longus have common synovial sheath vs separate?
common synovial sheath in superior peroneal retinaculum.
inferior peroneal retinaculum:
superior tunnel: peroneus brevis
inferior tunnel: peroneus longus
which common plantar digital nerve communicates with lateral plantar nerve?
3rd common plantar digital nerve
what is the orientations between the lateral plantar artery vs nerve
lateral plantar artery is lateral to lateral plantar nerve
what does the superficial branch of the lateral plantar nerve innervate
flexor digiti minimi brevis and 3rd plantar interossie and 4th dorsal interossei
what muscle does the nerve to abductor digiti minimi course across? what else courses across this muscle
quadratus plantae
lateral nerve and artery
what connects the bony phalanges to the flexor digitorum longus and brevis? where are they located? what is their main function?
short and long vinculas. (cord like structures)
short (brevis) vinculas are more distal, proxima(longus) vinculas are more proximal
Main function: carry blood vessels/supply nutrients to tendons
where does the lateral plantar artery usually split to its branches
at the base of the 5th met
what does the posterior perforating branches anastamose with
dorsal metatarsal arteries
what does the deep plantar arch anastamose with
lateral plantar br of the ramus profundus
deep plantar artery from dorsali pedis
what runs with the deep plantar arch
deep plantar arch runs with deep division of lateral platnar nerve
where do the plantar interossei originate
medial side of metatarsal 3,4,5
where does the medial plantar artery and nerve emerge from right when they branch off? where does the medial plantar nerve merge from before it becomes superficial to its tendons
origin of abductor hallucis muscle
emerges from below FDB and at distal part becomes superficial to its tendons
what follows the superficial fibular plantar artery
superficial branch of lateral plantar n
what gives rise to the proper plantar digital arteries?
common plantar digital arteries
where can the 1st proper plantar digital artery originate from
superficial tibial branch of medial platnar a or 1st planatar metatarsal artery
insertion of Tibialis posterior
navicular tuberosity, 2-4 metatarsal, all other tarsals except talus. (recurrent band of tibalis posterior at sustentaculum tali)
