- Third Cervical Nerve
The third cervical nerve is a mixed nerve, formed by the union of its posterior nerve root (sensory nerve fibers) with its anterior nerve root (motor nerve fibers). The roots emerge from the posterolateral and anterolateral sulci of the C3 spinal segment and unite to form the third cervical nerve.
15 Ιουν 2023 · 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.
C3 nerve root and ganglion compression, although uncommon, does occur. It presents with radiating pain, dysesthesias, numbness, and a C3 dermatome sensory deficit. The associated clinical syndrome resolves after facetectomy and C3 root and ganglion decompression.
24 Ιουλ 2023 · 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.
Cervical spinal nerves, also called cervical nerves, provide functional control and sensation to different parts of the body based on the spinal level where they branch out from the spinal cord. While innervation can vary from person to person, some common patterns include:
12 Δεκ 2020 · The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity.
