Osmosis video - Superficial structures of the neck: Cervical plexus

The cervical plexus is an important plexus of nerves that provide innervation to the head and neck. This plexus is located anteromedial to the levator scapulae and middle scalene muscles and deep to the sternocleidomastoid muscle. The cervical plexus forms from the anterior rami of spinal nerves C1, C2, C3, and C4. It is a mixed nerve plexus as it provides both sensory and motor nerve fibers. The sensory fibers provide sensation to the skin of the neck, upper chest, and shoulder regions, while the motor fibers provide innervation to the muscles in the neck, chest, and shoulder regions.
