GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord is divided into four different regions: the cervical, thoracic, lumbar and sacral regions (Figure 3.1).

Detailed explanation-2: -The sacral spine (sacrum) is located below the lumbar spine and above the tailbone, which is known as the coccyx. Five bones that are fused together make up the triangle-shaped sacrum, and these bones are numbered S-1 to S-5. Each number corresponds with the nerves in that section of the spinal cord.

Detailed explanation-3: -The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2).
