Question

List the five regions of the vertebral column, from upper to lower

a) Cervical, Thoracic, Lumbar, Sacral, Coccygeal
b) Upper, Middle, Lower, Sacrum, Coccyx
c) Cranial, Thoracic, Lumbar, Pelvic, Sacral
d) C1, C2, C3, C4, C5

Answer 1

The vertebral column consists of five regions in descending order: Cervical, Thoracic, Lumbar, Sacral, and Coccygeal. These regions together support the body and protect the spinal cord, with specific curvatures enhancing strength and flexibility.

Step-by-step explanation:

The five regions of the vertebral column, ordered from the uppermost region closest to the head to the lowest region farthest from the head, are:

1. Cervical (C1-C7 vertebrae)
2. Thoracic (T1-T12 vertebrae)
3. Lumbar (L1-L5 vertebrae)
4. Sacral (fusion of five sacral vertebrae)
5. Coccygeal (fusion of four coccygeal vertebrae)

Each region of the vertebral column serves a specific function in supporting the body and protecting the spinal cord, with curvature in the spine contributing to its strength and flexibility. These curvatures include the primary curves (thoracic and sacrococcygeal) and secondary curves (cervical and lumbar), which are essential for balance and upright posture.
