Notes from NEET topper
Vertebrae
Structure:
- The vertebral column consists of 33 vertebrae: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral (fused), and 4 coccygeal (often fused).
- Each vertebra has a central body, a vertebral arch, and several processes for muscular and ligamentous attachments.
Functions:
- Protect the spinal cord.
- Support the head and body.
- Provide attachment points for ribs and muscles.
- Facilitate flexible movement.
Together, ribs, joints, and vertebrae form a crucial part of the skeletal system, each contributing to the body’s protection, movement, and structural integrity.
