Video - Fascia, vessels and nerves of the upper limb

Fascia is a type of connective tissue that surrounds muscles, organs, and other structures in the body. It provides support and protection and helps to keep everything in its place. The upper limbs have superficial and deep fascia layers.

Superficial fascia is the closest layer to the skin, while deep fascia lies beneath it. The superficial fascia provides insulation, cushion and passageway of vessels and nerves and blood vessels, whereas the deep fascia envelopes and organizes muscles into compartments.
