Study Notes

Vertebral Column Curvatures

Vertebral curvatures can be primary or secondary.
Primary curvatures are present at birth.
Secondary curvatures develop after birth.

Vertebral Arch

Forms the posterior portion of each vertebra.
Consists of pedicles and laminae.
Contains the vertebral foramen.
Vertebral foramina align to form the vertebral canal.
The vertebral canal protects the spinal cord.

Cervical Vertebrae

C4 and C5 are examples of typical cervical vertebrae.
Cervical vertebrae have distinct features compared to thoracic or lumbar vertebrae.

Thoracic Vertebrae

Thoracic vertebrae have larger bodies than cervical vertebrae.
