Which nerves form the cervical plexus?

The cervical plexus is a network of nerves that originate from the spinal cord in the neck region, specifically from the first four cervical vertebrae. It consists of an intricate web of interconnected nerves that provide sensory and motor innervation to various regions of the head, neck, and upper limbs. The key nerves that form the cervical plexus include the lesser occipital nerve, greater auricular nerve, transverse cervical nerve, supraclavicular nerves, phrenic nerve, and branches of the ansa cervicalis. These nerves play a crucial role in controlling motor functions, providing sensation, and coordinating movements in the upper body.
