A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column. [1] [2] These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. [1]
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 ...
These nerves control the functions of the rest of the body. In humans, there are 31 pairs of spinal nerves: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. These nerve roots are named according to the spinal vertebrata which they are adjacent to.
The cervical spinal nerve 2 (C2) is a spinal nerve of the cervical segment. [1] It is a part of the ansa cervicalis along with the C1 and C3 nerves sometimes forming part of superior root of the ansa cervicalis. [2] it also connects into the inferior root of the ansa cervicalis with the C3. [2]
There is anastomosis with accessory nerve, hypoglossal nerve and sympathetic trunk. It is located in the neck, deep to the sternocleidomastoid muscle. [5] The branches of the cervical plexus emerge from the posterior triangle at the nerve point, a point which lies midway on the posterior border of the sternocleidomastoid.
The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. [1] C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami). It originates from the spinal column from above the cervical vertebra 1 (C1). [2]
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from above the cervical vertebra 6 (C6). The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including: Subclavius; Supraspinatus; Infraspinatus ...
