Cervical Spine lect and lab Flashcards
Week 2 lecture
What is a uncinate process?
stabilizer and guider of motion in the cervical verbrea.
When do uncinate processes devlop?
develops around 6-9 years of age
Why is there a bifid process on the spinous process in the cervical spine?
adds surface area for muscle attatchments.
What is a osteophyte?
a bony lump that grows on the outside of a bone. alos common result of the bodys attempt to repait damaged bone tissue or respond to stress.
Where is a common site for a osteophyte to develop?
Uncinate process.
Transverse foramen in cervical spine
C1-C6 for vetebral artry, gets stretched with movement.
C0 Occiput
rests on C1 (atlas) to form atlanto-occipialt joint.
What is unique about the condyles of the occipit?
They sit in the oblique plane, not strickly in the saggitial plane
What plane does the occiput move in extension and flexion?
saggital
What are the condyles on the occiput?
convex
C1
Atlats
What plane is C1 in
oblique plane to articulate with the occput
What is unique about C1
absent vertebral body, disc and spinous process
C2
Axis
what is unique about C2
absent vertebral disc and has the dens, large articular surfaces
Dens
bony prominace on C2 that points superiorly ans sits at the level of C1
Where does the nuchal ligament attach
external occipital protuberance to supraspinatus ligament
What does the nuchal ligament resist
flexion of cervial spine
Alar Ligament attachments?
dens of C2 to occiput condyles of occiput base
what does the alar ligamnt resist?
Limit excessive rotation, lateral bending, and flexion of the neck , stabilizes the AA joint and prevent translation.
Transverse ligmanet attachments?
trandverse ligament limits?
anterior translation of C1-C2 dens
tectoral membrane attachments
Axis C2 to occipital bone
Tectoral membrane function?
limits forward flexion
