The cervical plexus is a network of nerve fibres that supplies innervation to some of the structures in the neck and trunk. It is located in the posterior triangle of the neck, halfway up the sternocleidomastoid muscle, and within the prevertebral layer of cervical fascia.

Cervical Plexus Block Anesthesia Key

Cervical nerves are spinal nerves that arise from the cervical region of the spinal cord. These nerves conduct motor and sensory information via efferent and afferent fibers, respectively, to and from the central nervous system. While classified as peripheral nerves, the motor cell body resides in the anterior horn of the spinal cord.

The ansa cervicalis, which innervates the infrahyoid muscles, is a neural complex in the neck formed by the combination of the ventral rami of the first three or four cervical spinal nerves. It is comprised of both superior and inferior roots. The superior root of the ansa cervicalis, the ramus descendens hypoglossi, travels with the.

Ansa Cervicalis Head & Neck YouTube

The ansa cervicalis is formed by the union of its superior and inferior roots, which contain neuronal fibers from the first to third cervical spinal segments. Communicating motor neuronal fibers emerge from the loop between C1 and C2 and travel through the hypoglossal nerve.

The ansa cervicalis supplies the three out of four infrahyoid muscles: omohyoid, sternothyroid and sternohyoid. The fourth muscle, the thyrohyoid, is instead innervated by the nerve to thyrohyoid which is a branch of the hypoglossal nerve.
