Arteries and nerves of the foot
After completing this study unit you will be able to:
- Name the major arteries and nerves sources that supply the foot.
- List and identify the branches of the main arteries and nerves of the foot.
- Visualize the course of these structures and their anatomical relationships with each other.
The arterial supply to the foot can be divided into a dorsal and plantar component, that are connected through the pedal arches. The arteries of the foot originate from two major sources:
- Anterior tibial artery, which gives off a number of branches to supply the dorsum of the foot.
- Posterior tibial artery, which provides the branches for the plantar portion of the foot.
Five major nerves provide innervation to the foot; these are the tibial, sural, deep fibular, superficial fibular and saphenous nerves.
We’ll help you grasp this extensive topic with the following video tutorial.
