Vertebral Column
1. Structure
a. Extends from the skull to apex of coccyx
b. Length
i. Male + 70cm
ii. Female + 60 cm
c. 33 Vertebrae
i. 7 cervical
ii. 12 Thoracic
iii. 5 Lumbar
iv. 5 Sacral (fused to form sacrum)
v. 4 Coccygeal (fused to form coccyx)
d. Curved Spine
i. Acts like a spring – natural shock absorber
ii. Kyphosis – convex curvature
iii. Lordosis – concave curvature
2. Function
a. Protect spinal cord and spinal nerve
b. Supports body weight
c. Important to maintain posture and for locomotion
3. General Feature of Vertebral
a. Typical Vertebrae & Atypical Vertebrae
i. Typical vertebrae consist of:
1. Vertebral body
2. Vertebral arch (consist of Pedicle & Lamina)
3. TVP
4. SP
5. Articular process
6. Surface of Vertebral body that connects IVD
7. Vertebral foramina (form vertebral canal for spinal cord)
8. Intervertebral foramina (for spinal nerve)
ii. Typical Vertebrae
1. Cervical C3-C6
2. Thoracic T5-T8
3. Lumbar L1-L4
