The cervical spinal nerve 5 (C5) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 5 (C5). It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the ...
Cervical spinal nerve 4, also called C4, is a spinal nerve of the cervical segment. It originates from the spinal cord above the 4th cervical vertebra (C4). It contributes nerve fibers to the phrenic nerve , the motor nerve to the thoracoabdominal diaphragm .
However, the cervical spine is comparatively mobile, and some component of this movement is due to flexion and extension of the vertebral column itself. This movement between the atlas and occipital bone is often referred to as the "yes joint", owing to its nature of being able to move the head in an up-and-down fashion.
Phrenic (C3-C5, but mostly C4) - innervates thoracic diaphragm and the pericardium. Segmental branches (C1-C4) - innervate anterior and middle scalene muscles Levator scapulae muscle (C3-C4) (also innervated by dorsal scapular nerve (C5) of the brachial plexus )
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
Suprascapular paralysis, causing back pain, problems with abduction and external rotation of the humerus, and wasting away of supraspinatus and infraspinatus.
It formed by the coalescence of four ganglia, corresponding to the four upper-most cervical nerves C1–C4. The bodies of its preganglionic sympathetic afferent neurons are located in the lateral horn of the spinal cord. Their axons enter the SCG to synapse with postganglionic neurons whose axons then exit the rostral end of the SCG and proceed ...
Surgery to restore function and form of the spine Cervical spinal cord stimulation (cSCS) [ 26 ] When cervicocranial syndrome is caused by a mutation in genes and it runs in the family due to other co-morbidities, genetic counseling helps patients cover risks, prevention and expectations of caring and passing genes to a newborn.
