Study Notes
Composition of the Vertebral Column
- The vertebral column is composed of 33 vertebrae
- 7 cervical vertebrae
- 12 thoracic vertebrae
- 5 lumbar vertebrae
- 5 sacral vertebrae (fused to form the sacrum)
- 4 coccygeal vertebrae
- The vertebral column consists of 26 bones (7C+12T+5L+Sacrum+Coccyx)
Structure of the Vertebral Column
- The vertebral column is segmented
- Composed of vertebrae, joints, and pads of fibrocartilage called intervertebral discs
- The intervertebral discs form about one quarter the length of the column
- The vertebral column is a flexible structure due to its composition
