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:

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.

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.

The main sensory branches of the cervical plexus are the greater auricular nerve which innervates the external ear and skin over the parotid gland, the transverse cervical nerve which is responsible for sensation in the anterolateral neck and upper sternum, the lesser occipital nerve which innervates the posterosuperior scalp and the ...

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 t …

2022年1月4日 · Understanding the anatomy of your cervical spine and the vital nerves it contains should motivate you to adopt behaviors that help prevent neck injury and slow development of degenerative ...

Cervical nerves refer to the nerve roots composed of sensory and motor fibers that provide innervation to the head, neck, and upper extremities, originating from the cervical spinal cord and passing through the intervertebral foramen to innervate specific anatomical structures in …

2025年3月3日 · There are 8 pairs of spinal nerves in the cervical spine, labeled C1 to C8. Each one is named after the vertebra beneath it, except the C8 nerves, which are above the T1 vertebra. These nerves play important roles in sending messages to and from the spinal cord, enabling the brain to communicate with parts of the upper body.

2025年3月20日 · The cervical plexus is a collection of cervical nerves created by the anterior (ventral) rami of spinal nerves C1-C4 (sometimes known as the first through fourth cervical nerves). The cervical plexus’ roots (limbs) are shown here. The 5th cervical nerve (the anterior ramus of spinal nerve C5) may also be regarded as a member of the plexus ...
