Arteries and nerves of the foot
Completing this study unit will teach you how 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:
- The anterior tibial artery, which gives off a number of branches to supply the dorsum of the foot.
- The posterior tibial artery, which provides the branches for the plantar portion of the foot.
The branches of these two vessels anastomose with each other so that there’s no part of the foot left ‘thirsty’ for oxygenated, blood.
Now, the innervation is one of the students’ nightmare, as there are as many as five major nerves that provide the nerve branches of the foot. Namely, these are the tibial, sural, deep fibular, superficial fibular and saphenous nerves.
However, do not worry at all, we’ll help you grasp this extensive topic with the following video tutorial.
