C1 name
atlas
C2 name
axis
function of atlanto-occipital joints
- forward flexion and extension of the head
- lateral flexion of the head
what are the atlanto-axial joints
where the atlas and axis articulate
atlanto-axial joints function
rotation of the head
body location
neural arch location
vertebral foramen location
spinous process location
transverse process location
what is the articular pillar
mass of bone which connects the articular processes (one above and one below)
what is the articular pillar
mass of bone which connects the articular processes (one above and one below)
what connects two cervical vertebrae
- an intervertebral disk in front
- an intervertebral joint on each side
does the atlas have a body
no
main features of the atlas
- anterior arch
- posterior arch
- lateral masses
main feature of the axis
odontoid process
what holds odontoid process in place from behind
transverse ligament of the atlas
what holds the odontoid process in place from above
the alar ligaments
which part of the atlas does the odontoid process articulate with
the anterior arch
intervertebral joint classification
synovial joints
what are interverebral disks made of
fibrocartilage
where does the nucchal ligament extend from
spinous process of T1 to external occipital protuberence
nucchal ligament function
- limits forward flexion of head and cervical spine
- serves as attachment for major muscles
where does the anterior longitudinal ligament run
along the whole length of vertebral column connecting the fronts of the vertebral bodies
