Cervical and Thoracic Flashcards
what is the purpose of the cervical and thoracic spine?
movement of head; line of sight
what bones are included in the cervical and thoracic spine?
atlas, axis, C3-C7
describe the landmarks of the atlas
- No body
- Facet for dens (connects to other vertebrae below)
- Articular facets
- Transverse process
- Arches
describe the landmarks of the axis
- Has a body
- Dens (connects to other vertebrae)
- Articular facets
- Transverse process
- Spinous process (is palpable)
describe the landmarks of C3-C7
- Body
- Articular facets
- Transverse process
- Spinous process is short and divided
describe the function of the atlantooccipital joint
connects cranium to atlas - functions for “yes” nod
describe function of the atlantoaxial joint
connects atlas to axis - functions for “no” nod
describe kind of joint, bones involved, and movement of the articular vertebral joints
- Arthrodial
- Bones: sup art facets and inf art facets
- Movement: gliding for flexion, extension, SB, and rotation
describe kind of joint and parts of the C2-S1 vertebral joints
- Amphiarthrodial symphysis joints
- Parts: vertebral discs and vertebral bodies
describe the parts of intervertebral discs
- Outer layer = annulus fibrosus
- dense fibrocartilage
- Inner layer = nucleus pulposus
- gelatinous/pulpy substance
what is the function of intervertebral discs?
Function to compress vertebral bodies in all directions
what is a herniation and what affect does it have on the functionality of the spine?
when the nucleus pulposus protrudes annulus fibrosus
Changes to annulus decrease resilience
what are the landmarks of the thoracic spine?
- Body
- Articular facets: costal facets
- Transverse process
- Spinous process: long and downward pointing
how many total ribs are there and how are they put into groups?
12 pairs
- 7 true ribs
- 5 false ribs: 3 indirect, 2 floating
what are the landmarks of the ribs?
head, neck, shaft, tubercle
describe cervical flexion and include degrees of motion
chin to chest - 45 degrees
describe cervical extension and include degrees of motion
look up - 45 degrees
