Lecture 1 Flashcards
What is C1 called?
Atlas
What is C2 called?
Axis
What does the vertebral body do?
weight bearing
What are the transverse processes for?
muscle attachments
What is a facet joint?
joint where superior and inferior articular processes meet with articular process of adjacent vertebrae
what does the inferior articular process do?
connects one vertebrae to the next
where is the transverse foramen found?
found only in cervical vertebrae
what does the transverse foramen do?
allows passage for vertebral NAV
Where is the superior articular facet found?
only on C1
What does the superior articular facet do?
bears occipital condyles
Where are the lateral masses found?
C1
What are the lateral masses?
helps to transfer weight from skull
Where is the groove for the vertebral artery found?
C1
Where is the dens found?
C2
What does the dens do?
pivot joint to allow movement of head
What is an axis fracture?
“hanging fracture”
fractures the pars interarticularis
not cause of death; puts pressure on spinal cord
Where are the bifid spinous processes found?
cervical vertebrae
What is the uncinate process?
on cervical vertebrae
surrounds adjacent vertebrae to cradle and stablize
What is the vertebral prominens?
spinous process on C7
Where is the hyoid bone located?
Anterior neck by C3
muscle attachment supra- and infrahyoid muscles
communicates with larynx
What is the atlanto-occipital joint?
articulation between atlas and cranium
nodding head “yes”
What is the lateral atlantoaxial joint?
pivot joint
shaking head “no”
What is the uncovertebral joint?
contacts between vertebral bodies
What is there intervertebral joint?
fills intervertebral discs
