Lecture: Veins and Lymphatics - Matz

Question 1

how many valves?
great saphenous
small saphenous

Answer 1

10-20(more numerous in leg than thigh)

9-12

Question 2

which side of the tendocalcaneus is the small saphenous v

Answer 2

lateral

Question 3

why venae comitantes?

Answer 3

heat exchange

when hot - venae comitantes engorged

Question 4

tributaries to femoral v

Answer 4

popliteal
deep femoral
medial and lateral circumglex femoral
great saphenous

Question 5

popliteal v is _____ to a

Answer 5

superficial

- most superficial structue (think of small saphenous entering in to it)

Question 6

the femoral v is ______ to a ***

Answer 6

posterolateral

- in triangle lies medial to the a

Question 7

joins superficial and deep veins

Answer 7

perforating veins

Question 8

dodd veins

Answer 8

femoral canal perforators (adductor canal)

Question 9

boyd veins

Answer 9

paratibial perforator (calf m)

Question 10

cockett veins

Answer 10

posterior tibial perforators (proximal to ankle joint)

Question 11

bassi veins

Answer 11

peroneal or lateral calf perforators (5-7 cm above lateral malleolus)

Question 12

lymph traveling with great spahenous v end in

Answer 12

inferior group of superficial inguinal nodes

Question 13

lymphatics
dorsalis pedis and anterior tibial -->
medial and lateral plantar  --->
posterior tibial and peroneal -->
femoral, deep femoral -->

Answer 13

ant. tibial node
popliteal
popliteal
deep inguinal

Question 14

where do lymph vessels begin?

Answer 14

blind-ended capillaries

Question 15

how many popliteal lymph nodes

Answer 15

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

Question 16

lop-sided T of superfiical inguinal nodes

Answer 16

horizontal/superior group (parallels inguinal ligament, afferents from superior and lateral gluteal regions, anterior abdominal wall and perineum)

vertical/inferior group (parallels terminal portion of great saphenous v, afferents from foot, leg, thigh and perineum)

efferents from here pass to external iliac nodes

Question 17

name uppermost inguinal node

Answer 17

gland of cloquet or node of rosenmuller

Question 18

receives afferents from pelvis and deeped aspects of the gluteal region

Answer 18

internal iliac nodes (located within pelvis)

Question 19

generally indicates infection localized within the perineum

Answer 19

swollen superficial inguinal nodes

Question 20

generally indicates infection localized with the lower limb

Answer 20

swollen deep infuinal nodes
