The spinal cord is divided into four main areas, and each area has its own special job:

1. Cervical (C1-C8):

   • This part has 8 pairs of nerves.
   • It helps control movement and feeling in the neck, arms, hands, and diaphragm (the muscle that helps you breathe).
   • It also affects some parts of the chest.

2. Thoracic (T1-T12):

   • This section has 12 pairs of nerves.
   • It mainly helps with the trunk (the main part of your body) and the upper belly.
   • It plays a part in moving the chest muscles and the arms.

3. Lumbar (L1-L5):

   • This area has 5 pairs of nerves.
   • It is important for the lower back, legs, and feet.
   • These nerves help with movement and feeling in the lower body.

4. Sacral (S1-S5):

   • This part includes 5 pairs of nerves.
   • It controls the organs in the pelvis, the lower limbs (legs), and some functions of going to the bathroom (bowel and bladder).

5. Coccygeal (Co1):

   • This section has 1 pair of nerves.
   • It mainly serves the skin over the tailbone area (coccyx).

Overall, the spinal cord sends messages between the brain and the body. It has about 31 pairs of spinal nerves in total, which help with important movements and feelings in your body.
