Title: Cervical Spine Anatomy


1
Cervical Spine Anatomy
2
General Vertebral Anatomy
  • Body
  • Vertebral Arch
  • Pedicles
  • Laminae
  • Vertebral Foramen
  • Spinous Process
  • Facets
  • Superior Articulating Surface
  • Inferior Articulating Surface
  • Transverse Process
  • Intervertebral Foramen

3
Distinguishing Features of Cervical Vertebrae
  • Transverse foramina
  • C1 transverse process
  • Spinous Processes
  • C6 and C7
  • C3-C6 bifurcate
  • None for C1
  • Articulating Facets

4
Atlas
  • 1st Cervical Vertabrae
  • Lack of Body
  • Superior Articular Foveae
  • Inferior Articulating Foveae
  • Fovea Dentis

5
Axis
  • C2
  • Dens
  • Rotation between skull and atlas

6
C7
  • Body
  • Spinous process
  • Transverse Foramina
  • Anterior element

7
Articulations within cervical region
  • Lateral Atlantoaxial Joints
  • Superior facets and inferior facets of atlas
  • Flat and in transverse plane
  • Rotation
  • Side toward rotation
  • Side away from rotation
  • Median Atlantoaxial Joints
  • Dens of axis and anterior arch of atlas
  • Tectorial membrane
  • Cruciform ligament

8
Articulation within cervical spine
  • Atlanto-occipital
  • Occipital condyles of skull and superior
    articulating surface of atlas
  • Rotation

9
Articulations within cervical spine
  • Body-to-body articulation
  • Fibrocartilogenous Intervertebral Disk
  • Annulos fibrosis
  • Nucleus puplosis

10
Articulations within cervical spine
  • Cervical facet joints
  • Parallel to frontal plane
  • 45 degrees to transverse plane
  • Rotation

11
Ligaments within cervical spine
  • Ligamentum Nuchae
  • Interspinous Ligament
  • Ligamentum Flava
  • Posterior Atlanto-occipital membrane
  • Intertransverse Ligament

12
Curvature of cervical spine
  • Lordotic Curve

13
Cervical spine movement
  • Flexion/Extension
  • Atlanto-occipital
  • Rotation
  • Atlanto-axial joint

14
Muscles of cervical spine
  • See alternate power point

15
Brachial Plexus
  • Nerve Roots
  • C5,6,7,8,T1
  • Trunks
  • Upper
  • Middle
  • Lower
  • Divisions
  • Anterior
  • Posterior
  • Cords
  • Lateral
  • Posterior
  • Medial
