Which spinal curves are primary?
- thoracic
- sacral
Which spinal curves are secondary?
- cervical
- lumbar
What are primary curvatures?
- curvatures that develop prenatally
What are secondary curvatures?
- curvatures that develop postnatally from sitting and standing up
Describe cervical vertebrae?
- Cervical vertebrae are the only vertebral type that has transverse foramina.
- cervical vertebrae are small
- and have a short, bifid (split at the end) spinous process.
Describe thoracic vertebrae?
- look like a giraffe head from the lateral view with a long, sloping spinous process. - - They also have costal facets on the transverse processes (T1-T10) where they articulate with ribs.
Describe lumbar vertebrae?
- look like a moose head from the lateral view with a thick, broad spinous process.
- lumbar vertebrae have thin, extended transverse processes and large, distinct articular processes with almost vertical facets.
How do atlas and axis articulate with the occipital bone?
- The occipital condyles of the occipital bone sit on the superior articular facets of the atlas.
- The dens of the axis extends through the vertebral foramen of the atlas next to the anterior arch
What type of vertebrae is the hyoid associated with?
cervical
What bone articulates with the glenoid cavity?
the head of the humerous
Is the spine of the scapula on the posterior or anterior region of the scapula?
posterior
What two areas on the scapula does the scapular spine fall between?
- interspinous and supraspinous fossa
