A Neurovascular bundle (Neuro: Nerve, Vascular: Veins, Lymph vessels and arteries) is a term applied to the body nerves, arteries, veins and lymphatics that tend to travel together in the body. As arteries do not travel within the superficial fascia (loose connective tissue under the skin), superficial neurovascular bundles differ from deep neurovascular bundles in both composition and function. For example, in Thoracic Outlet Syndrome, the neurovascular bundle containing the Subclavian Artery and the Brachial Plexus are compressed.
