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:

2023年7月24日 · 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 nerves C1, C2 and C3 control your forward, backward and side head and neck movements. The C2 nerve provides sensation to the upper area of your head; C3 gives sensation to the side of your face and back of your head.

2023年11月14日 · Nerves roots of C1-C3: supply prevertebral muscles. The cervical plexus also contributes branches to these nerves: Dorsal scapular (C4,5): supplies the rhomboid major and minor, and levator scapulae muscles. Long thoracic (C5-7): supplies the serratus anterior muscle.

2025年1月24日 · Impact of Lower Cervical Nerves. Understanding the impact of lower cervical nerves (C5-C8) is crucial because of their significant role in upper limb function and sensation. These nerves control motor functions in the shoulders, arms, and hands, and provide sensory input from these areas. Impairment of these nerves can lead to widespread ...

2023年10月12日 · In this article, we shall look at the anatomy of the cervical plexus – its branches, functions and clinical correlations. Anatomical position of the cervical plexus within the neck. Access this feature with pro. The spinal nerves C1 …

2023年10月24日 · Nerves. The cervical spine functions as the spinal cord's bony protection as it exits the cranium. Despite there being only 7 cervical vertebrae, there are 8 pairs of cervical nerves, termed C1 to C8. The first 7 cervical nerves exit the spine cranially to their associated vertebrae, while the 8th cervical nerve exits caudally to C7 (see Image ...

There are 8 pairs of spinal nerves in the cervical spine, labeled C1 to C8. These nerves play important roles in sending messages to and from the spinal cord.

2023年8月28日 · Seven cervical vertebrae, combined with cartilages, various ligaments, and muscles, make a sophisticated and flexible structure that allows a variety of head/neck movements. Similar to other areas of the spine, cervical vertebrae also have intervening intervertebral disks for shock absorption and flexibility.

2023年7月24日 · 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.
