A significant correlation was found between decreased mobility in motion segment C7-T1 and T1-T2 and increased risk for neck- shoulder pain. [ 1 ] [ 4 ] Norlander and Nordgren [ 5 ] have also shown that several clinical symptoms show relationship to segmental mobility examined with CTR.
The cervical spinal nerve 7 (C7) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from above the cervical vertebra 7 (C7). It runs through the interspace between the C6 and C7 vertebrae.
The two areas of the spinal cord most commonly injured are the cervical spine (C1–C7) and the lumbar spine (L1–L5). (The notation C1, C7, L1, L5 refer to the location of a specific vertebra in either the cervical, thoracic, or lumbar region of the spine.) Spinal cord injury can also be non-traumatic and caused by disease (transverse ...
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.
The thoracic spinal nerve 1 (T1) is a spinal nerve of the thoracic segment. [ 1 ] It originates from the spinal column from below the thoracic vertebra 1 (T1).
This is true for all spinal nerves except for the first spinal nerve pair (C1), which emerges between the occipital bone and the atlas (the first vertebra). [3] Thus the cervical nerves are numbered by the vertebra below, except spinal nerve C8, which exists below vertebra C7 and above vertebra T1.
The lateral grey column is present at 17 levels of the spinal cord, specifically through levels T1-L2 (sympathetic outflow) as well as through levels S2-S4 (parasympathetic outflow). [5] Both these segments are located within the first thoracic vertebra to the first or second lumbar vertebra as the spinal cord ends here and the nerves form the ...
The vertebral foramen is the large opening posterior to the vertebral body also known as the spinal canal. It contains and protects the spinal cord at the thoracic level. The spinous process is long, triangular on coronal section, directed obliquely downward, arising from the lamina and ending in a tuberculated extremity. These processes ...
