Vasa nervorum

Vasa nervorum are the small blood vessels that supply nerves with oxygen and nutrients. They are essential for the proper functioning of the nervous system.

Anatomy

The vasa nervorum are composed of small arteries, arterioles, capillaries, venules, and veins. They originate from the main blood vessels that supply the area where the nerve is located. The vasa nervorum follow the course of the nerve, branching off to supply the nerve at various points along its length.

Function

The primary function of the vasa nervorum is to provide the nerve with the necessary oxygen and nutrients it needs to function. They also remove waste products from the nerve. Without the vasa nervorum, nerves would not be able to function properly, leading to a variety of neurological disorders.

Clinical significance

Damage to the vasa nervorum can lead to a variety of medical conditions. For example, in diabetes mellitus, high blood sugar levels can damage the vasa nervorum, leading to diabetic neuropathy. This can cause a variety of symptoms, including pain, numbness, and weakness in the affected nerves.
