Vacsularization of the foot Flashcards
Do superficial veins on the dorsum of the foot have corresponding arteries?
NO
superficial veins on the dorsum of the foot connect to deep veins by
perforating veins
superficial veins on the dorsum of the foot are commonly accompanied by
cutaneous nerves
the dorsum of each toe is drained by
- dorsal digital veins
2. median digital vein
dorsal digital veins
drain the side of the toes
median digital vein
drains the center of the toe and nail matrix
The median digital veins drain into
the dorsal digital veins on the sides of the toes
dorsal digital veins from adj side of the toes unite with———from————–to form————–
intercapitular vein
plantar cutaneous venous arch
common digital vein
what structures flow into the dorsal venous arch?
- common digital vein
- dorsal digital vein from dorsomedial aspect of the hallux
- dorsal digital vein from dorsolaeral aspect of the digiti minimi
dorsal venous arch flows medially to the ————and laterally into the ————
medial marginal vein
lateral marginal vein
dorsal venous arch is located ———to cutaneous nerves
superficial
what structures form medial marginal vein?
the dorsal digital vein on the dorsomedial aspect of the hallux and dorsal venous arch unite to form the medial marginal vein
—————–courses with the medial marginal vein
saphenous nerve
The medial marginal vein courses ————-to medial malleolus and become —————–
Anterior
Great saphenous vein
Great saphenous vein courses up the leg and thigh and courses through the ——–opening and below the —————ligament to drain into ———–vein.
saphenous
inguinal
femoral
what structures form the lateral marginal vein
dorsal digital vein on the dorsolateral aspect of the 5th toe and the dorsal venous arch
———courses with the lateral marginal vein
lateral dorsal cutaneous nerve
the lateral marginal vein courses ——–to the lateral malleolus and becomes the ———–which courses up the leg and pierces the —————to drain into the —————–.
posterior
small saphenous vein
popliteal fascia
popliteal vein
great saphenous vein drain into
femoral vein
small saphenous vein drain into
popliteal vein
when the lateral marginal vein is absent , the small saphenous vein is formed from
superficial veins on the lateroplantar aspect of the foot
where is plantar cutaneous venous arch located ?
in the superficial fascia in the region of the MTP
plantar cutaneous venous arch gives off
4 intercapitular veins to the dorsum of the foot
plantar cutaneous venous arch is continuous with
medial and lateral marginal vein
the superficial veins are——-organized in the plantar surface of the foot
LESS
The dorsum of the foot is vascularized by what artery
dorsalis pedis artery
dorsalis pedis artery is a continuation of
Anterior tibial a
the arteries on the dorsum of the foot are——-than the arteries on the plantar surface of the foot
much smaller
the arteries are accompanied by —————of the same name
deep veins
deep veins course with the arteries and are usually paired forming
vinae comitantes ( accompanying veins)
dorsalis pedis artery begins at
articular capsule of the ankle joint
dorsalis pedis artery courses
deep to deep fascia
over the neck of the talus
navicular
2nd cuneiform
where does the dorsalis pedis artery terminate?
at the proximal aspect of 1st interspacemit terminates by dividing into the 1st dorsal metatarsal artery and the deep plantar artery
what tendon is located on the medial side of the dorsalis pedis artery
tendon of EHL
what tendon cross the dorsalis pedis artery near its termination
tendon of EHB
what are major branches of dorsalis pedis artery
- Artery of the sinus tarsi
- Lateral tarsal artery
- Medial tarsal arteries
- Arcuate a.
- 1st dorsal metatarsal a.
- Deep plantar a.
what is the name of the branch of dorsalis pedis artery at the level of the neck of the talus?
Artery of sinus tarsi
Artery of sinus tarsi provide the major vascular supply to
Talus
Artery of sinus tarsi terminates by anastomosing with
artery of tarsal canal from the posterior tibial a.
Lateral tarsal a. is a branch of the dorsalis pedis a at the level of
neck of the talus or navicular
lateral tarsal a courses laterally with what nerve?
lateral terminal branch of deep fibular n.
lateral tarsal a courses laterally deep to
EHB
EDB
lateral tarsal a terminates by anastomosing with
anterior lateral malleolar
perforating
arcuate
