Anatomy of cervical spine

Anatomy of cervical spine

1. ANATOMY OF CERVICAL SPINE

2. Introduction The cervical spine made of 7 vertebrae C3-C6 are called typical vertebrae and C1,2 & 7 are considered atypical

3. Typical vertebra Bifid spinious process Large triangular vertebral foramen Superior and inferior facets are flat Transverse processes are small and pierced by foramen transversarium .

4. C7 differs slightly from typical vertebra Long non bifid spinous process (vertebra prominens ) Vestigial anterior tubercle Small foramen transversarium containing vein only.

5. C1-Atlas Has no body or spine Consists of right and left lateral masses coonected by a short anterior arch & long curved posterior arch

6. C2-Axis Presence of Odontoid process Bifid spine Absent ant. tubercle of transverse process Thick lamina

7. Joints in the cervical spine Intervertebral joints Between vertebral bodies Secondary cartilaginous joints Joints of Lushka Between vertebral arches Zygohypophyseal joints Intervertebral syndesmoses Craniovertebral joints

8. Zygohypophyseal joints

9. Atlantoaxial joint

10. Ligaments of cervical spine

11. Movements of cerVICal spine Flexion Extension Lateral flexion Rotation

12. 50% of flexion/extension occurs at atlanto -occipital jt 50% of rotation occurs at atlantoaxial jt

13. Applied anatomy

14. Cervical disc prolapse
