MICROANATOMY

Detailed explanation-1: -More specifically, there are eight cervical nerve pairs (C1-C8), twelve thoracic nerve pairs (T1-T12), five lumbar nerve pairs (L1-L5), 5 sacral (S1-S5), and a single coccygeal nerve pair.

Detailed explanation-2: -Eight pairs of spinal nerves exit through small openings (foramen) between every pair of vertebrae in your cervical spine. They’re labeled C1 through C8. They stimulate muscle movement in your neck, shoulder, arm and hand, and provide sensation.

Detailed explanation-3: -There are 31 pairs of spinal nerves and roots. Eight pairs of cervical nerves exit the cervical cord at each vertebral level. One member of the pair exits on the right side and the other exits on the left.

Detailed explanation-4: -Radiographs of the cervical spine showed no signs of trauma. However, it was noted that the cervical spine comprised 8 vertebrae instead of the usual 7 (Fig. 1). In addition, the thoracic radiograph demonstrated 13 vertebrae (Fig.
