Cervical Spine
Atypical Cervical Vertebra
C1:
- Posterior tubercle instead of spinous process.
C2:
- Has dens
C7:
- Elongated and non-bifid spinous process
Anterior Longitudinal Ligament
Posterior Longitudinal Ligament
Ligamentum Flavum
Interspinous Ligament
Ligamentum Nuchae
Intertransverse ligament
In the Cx spine these types of fibres can be sparse and intertwined with the posterior intertransversariicolli muscles (providing stability in Cx lateral flexion)
Cervical Spine ROM
Thoracic Spine
Atypical Thoracic Vertebra
T1:
- Superior costal facets are ‘whole’ as C7 does not have an inferior costal demifacet
T9:
- Has no inferior demifacet so does not connect to the 10th rib
T11 & 12:
- Single costal facets (T11=11th rib, T12=12th rib)
:
T10
- Sometimes has the same feature as T11 &12
- Important to appreciate anatomical variances
Thoracic Cage
Typical Rib Features
Head:
- Where articular facets are located
Neck:
- Extends from the rib head to the tubercle
Tubercle:
- Articulates with transverse process to create
the costotransverse joint
Body:
- Containing costal groove that houses intercostal vein/artery/nerve
Lumbar Spine
Facet Joint Orientation **NEED TO FILL
Cervical:
- Coronal
Lumbar:
- Saggital
Flexors of the Trunk
Extensors of the Trunk
Rotators of the Trunk
Lateral Flexors of the Trunk
Pelvis
Gender Dimorphism in the Pelvis
Female differences:
- Wider and broader yet lighter
- Oval-shaped inlet versus heart shaped
- Less prominent ischial spines = greater
bispinous diameter
- Greater sub-pubic arch angle
- Shorter, more curved sacrum
