A

dorsal a. of the foot (dorsalis pedis a.)

36
Q

Which artery supplies the muscles on the dorsum of the foot?

A

dorsal a. of the foot (dorsalis pedis a.)

37
Q

Which artery pierces the 1st dorsal interosseous muscle as deep plantar artery to contribute to formation of plantar arch?

A

dorsal a. of the foot (dorsalis pedis a.)

38
Q

What is the origin of the posterior tibial a.?

A

popliteal a.

39
Q

Which artery supplies the posterior and lateral compartments of the leg?

A

posterior tibial a.

40
Q

A

posterior tibial a.

41
Q

What is the origin of the fibular a.?

A

posterior tibial a.

42

44
Q

Which artery is the direct continuation of the anterior tibial a.?

A

dorsal artery of foot (dorsalis pedis a.)

45
Q

The dorsal artery of foot/ dorsalis pedis a. divides into….

A

-1st dorsal metatarsal a.
-deep plantar a.

46
Q

The 1st dorsal metatarsal a. passes deeply between the heads of the 1st dorsal interosseous muscle to enter the sole of the foot where it JOINS the ______________ a. to FORM the ______________

A

lateral plantar, deep plantar arch

47
Q

Which artery divides into 2 branches that supply both sides of the great toe and the medial side of 2nd toe?

A

1st dorsal metatarsal a.

49
Q

Which a. anastomoses with the arcuate a.?

A

lateral tarsal a.

50
Q

Which artery gives rise to the 2nd, 3rd, and 4th dorsal metatarsal arteries?

A

arcuate a.

(these vessels run distally to the clefts of the toes and are connected to the plantar arch and to the plantar metatarsal arteries by perforating branches)

51
Q

Distally, each _________________ artery divides into 2 dorsal digital arteries for the dorsal aspect of the sides of adjoining toes; however, these arteries generally end proximal to the distal interphalangeal joint and are replaced by or receive replenishment from dorsal branches of the plantar digital arteries

Q

Which artery is the smaller terminal branch of the posterior tibial a.?

A

medial plantar a.

53
Q

A

medial plantar

54
Q

A

lateral plantar

55
Q

A

deep plantar arch

56
Q

What gives rise to 4 plantar metatarsal arteries, 3 perforating branches, and many branches to the skin, fascia, and muscles in the sole?

A

deep plantar arch

57
Q

Which arteries give rise to the plantar digital arteries?

A

plantar metatarsal arteries

58
Q
