Structures which are vital for maintaining the health and functionality of blood vessels and nerves

Vasa Vasorum

• Definition: Small blood vessels that supply the walls of larger arteries and veins.
• Function: Provide nourishment to the outer layers (tunica externa) of large blood vessels, as diffusion from the lumen is insufficient for thick vessel walls.

Vasa Nervorum

• Definition: Small arteries that supply blood to peripheral nerves.
• Function: Provide essential nutrients to the interior parts of nerves and their coverings, crucial for nerve function and survival.

Nervi Vasorum

• Definition: Nerves that innervate blood vessels.
• Function: Control vasodilation and vasoconstriction, regulating blood flow and pressure.

Nervi Nervorum

• Definition: Nerves that innervate the connective tissue sheaths of peripheral nerves.
• Function: Involved in the sensation and regulation of pain within nerve sheaths, though not directly covered in the search results, they are known for their role in nerve health and pain perception.
