Flashcards in Arteries of the lower limb: in the foot Deck (9):
1

describe the course of travel of the dorsalis pedis

passes over dorsal aspect of tarsal bones before moving to the sole of the foot
then anastomose with lateral plantar artery to form deep plantar arch

2

Which structures does the dorsalis pedis supply?

tarsal bones and dorsal aspect of the metatarsals
contributes to supply of toes via the deep plantar arch

3

Describe the course of travel of the posterior tibial artery

enters the sole of the foot via the tarsal tunnel - then splits into medial and lateral plantar arteries

4

What does the posterior tibial artery supply?

sole of foot and toes and via the deep plantar arch (lateral & medial plantar arteries)

5

Clinical: pulse points in the lower limb
What are the 3 main pulse points in the lower limb?

1. femoral
2. popliteus
3. dorsalis pedis

6

Where can the femoral pulse be palpated?

as the femoral artery enters the femoral triangle
mid-inguinal point - between ASIS and pubic synthesis

7

Where can the popliteal artery be pulpated?

hardest pulse to find - deep in popliteal fossa: ask patients to slightly flex their legs - relaxes fascia around popliteal fossa
deep palpation

8

Where can the dorsalis pedis pulse be palpated?

palpated on dorsum of foot
lateral to extensor hallucis longus tendon

9

Which 2 arteries provide arterial supply to the foot?

1. dorsalis pedis (continuation of anterior tibial artery)
2. posterior tibial
