Neurovascular is a bundle like structure that binds veins and nerves with the help of connecting tissues. The two types of neurovascular bodies are superficial bundles and deep bundles. Both bundles differ in composition and function. Superficial Bundles: It consists of nerves and capillaries. The capillaries have a large surface area and short diffusion path which act as the sites for substance exchange between blood and interstitial fluid. The capillaries are made up of a central lumen lined with an endothelium( a single layer of epithelial cells). Deep bundles: It has a more complex structure than superficial neurovascular bundles. It includes arteries and these bundles have connective issues outside the endothelium. This bundle like structure let arteries to relax, contract, and transfer blood when under pressure.
