Artery Of The Foot

Question 1

What are the two main arteries that supply blood to the foot?

Answer 1

1. Dorsalis pedis
2. Posterior tibial artery

The dorsalis pedis is a continuation of the anterior tibial artery.

Question 2

Where does the dorsalis pedis artery begin?

Answer 2

As the anterior tibial artery enters the foot

The dorsalis pedis artery moves over the dorsal aspect of the tarsal bones.

Question 3

What is the path of the dorsalis pedis artery in the foot?

Answer 3

Passes over the dorsal aspect of the tarsal bones, then moves inferiorly towards the sole of the foot

It connects with the lateral plantar artery to form the deep plantar arch.

Question 4

What does the dorsalis pedis artery supply?

Answer 4

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

The deep plantar arch is formed by the connection with the lateral plantar artery.

Question 5

How does the posterior tibial artery enter the foot?

Answer 5

Through the tarsal tunnel

The posterior tibial artery then splits into the lateral and medial plantar arteries.

Question 6

What are the branches of the posterior tibial artery?

Answer 6

Lateral plantar artery and medial plantar artery

These arteries supply the plantar side of the foot.

Question 7

What is the function of the lateral and medial plantar arteries?

Answer 7

Supply the plantar side of the foot and contribute to the supply of the toes via the deep plantar arch

This branching allows for an adequate blood supply to the entire foot.
