Detailed explanation-1: -The cervical plexus is a complex neurologic structure located within the head and neck . The large portion of the cervical plexus is the communication between the anterior divisions of C1 through C4 nerves.
Detailed explanation-2: -The cervical plexus is formed in the neck region. It lies deep to the sternocleidomastoid muscle, and anterolateral to the levator scapulae.
Detailed explanation-3: -The cervical plexus is formed from the ventral rami of the upper four cervical nerves (Figure 4-22, B). Their dorsal and ventral roots combine to form spinal nerves as they exit through the intervertebral foramen.
