What are the Divisions of spinal colum?

The spinal column, also known as the vertebral column or backbone, is divided into five main regions:

1. Cervical Spine: The cervical spine, also known as the neck, consists of seven vertebrae labeled C1 to C7. It supports the head and allows for a wide range of movement, including nodding, shaking, and turning the head.

2. Thoracic Spine: The thoracic spine consists of twelve vertebrae labeled T1 to T12. It is the longest region of the spinal column and provides attachment points for the ribs, forming the rib cage. The thoracic spine protects vital organs such as the heart and lungs.

3. Lumbar Spine: The lumbar spine consists of five vertebrae labeled L1 to L5. It is the region of the back that bears most of the body's weight and is commonly referred to as the lower back. The lumbar spine provides support and flexibility during activities such as lifting, bending, and twisting.

4. Sacral Spine: The sacral spine consists of five fused vertebrae labeled S1 to S5, forming the sacrum. The sacrum is a triangular-shaped bone located at the base of the spine and connects to the hip bones. It provides stability and support to the pelvis and transmits weight from the spine to the lower extremities.

5. Coccygeal Spine: The coccygeal spine, also known as the tailbone, consists of four small, fused vertebrae labeled Co1 to Co4. It is the vestigial remnant of the tailbone and has minimal functional significance in humans.

These five divisions of the spinal column work together to provide structural support, protect delicate neural structures, and facilitate various movements of the head, neck, back, and trunk.
