6. Describe the typical contents of a neurovascular bundle.

All visceral structures, including muscle and skin, require four things to function properly:

• Blood supply via arteries

• Drainage of low-oxygen blood to heart via veins

• Drainage of fluids, proteins, and cellular debris via lymphatics

• Innervation (communication with the CNS) via nerves 

These structures often travel together in a neurovascular bundle. These bundles are often wrapped or enveloped in deep investing fascia. When considering muscle, the neurovascular bundle typically are located deep to the muscle.
