Cervical Spinal Nerves - Spine-health
Each spinal nerve has its own anterior and posterior roots. Each level of the cervical spine has four nerve roots—two on each side—that branch off from the spinal cord. The two types of nerve roots on each side include:

2023年7月24日 · The cervical nerves arise from the spinal cord in the form of rootlets, or fila radicularia, smaller neuron bundles that coalesce to form roots. For each spinal nerve, an anterior and posterior root join to form the completed nerve. Shortly after branching out of the spinal cord, the cervical nerves form the cervical and brachial plexuses.

2023年11月14日 · The cervical spinal cord is the site from which many important nerves arise. Many of these nerves originate in one of two plexuses: the cervical or brachial plexus. Cervical plexus Arises from the anterior rami of the spinal nerves associated with C1-C4 (some texts include the C5 nerve root).

2023年10月30日 · C1-C7 spinal nerves emerge from the vertebral canal above the corresponding vertebra, with an eighth pair of cervical spinal nerves emerging below the C7 vertebra, meaning there are a total of 8 pairs of cervical spinal nerves while there are only 7 cervical vertebrae.

2023年6月15日 · The cervical plexus is a conglomeration of cervical nerves formed by the anterior (ventral) rami of spinal nerves C1-C4 (a.k.a. 1st-4th cervical nerves). These are the roots (limbs) of the cervical plexus.

2023年10月12日 · 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 Nerve Root - an overview | ScienceDirect Topics
As the dorsal and ventral contributions to the cervical nerve roots move away from the cervical spinal cord, they coalesce into a single anatomic structure that becomes the individual cervical nerve roots.

2023年8月28日 · Each cervical spine has two nerve roots on each side, which arise from the spinal cord in the vertebral foramen. They are the ventral root (located posteriorly) and the dorsal root (located anteriorly).
