Lecture: Veins and Lymphatics - Matz Flashcards
how many valves?
great saphenous
small saphenous
10-20(more numerous in leg than thigh)
9-12
which side of the tendocalcaneus is the small saphenous v
lateral
why venae comitantes?
heat exchange
when hot - venae comitantes engorged
tributaries to femoral v
popliteal
deep femoral
medial and lateral circumglex femoral
great saphenous
popliteal v is _____ to a
superficial
- most superficial structue (think of small saphenous entering in to it)
the femoral v is ______ to a ***
posterolateral
- in triangle lies medial to the a
joins superficial and deep veins
perforating veins
dodd veins
femoral canal perforators (adductor canal)
boyd veins
paratibial perforator (calf m)
cockett veins
posterior tibial perforators (proximal to ankle joint)
bassi veins
peroneal or lateral calf perforators (5-7 cm above lateral malleolus)
lymph traveling with great spahenous v end in
inferior group of superficial inguinal nodes
lymphatics dorsalis pedis and anterior tibial --> medial and lateral plantar ---> posterior tibial and peroneal --> femoral, deep femoral -->
ant. tibial node
popliteal
popliteal
deep inguinal
where do lymph vessels begin?
blind-ended capillaries
how many popliteal lymph nodes
6/7 in three groups
anterior to popliteal a: knee jt
posterior to popliteal a: vessels coursing with small saphenous v
side of popliteal a: vessels that course with ant and post tib and peroneal a
efferents from here will drain into deep inguinal nodes
