23
Q

on each vertebrae, there is a superior vertebral notch and inferior vertebral notch located above and below each pedicle forming the

A

intervertebral foramina (rt. and lt)

24
Q

There are _ disks located between each vertebrae except between C-1 and C-2

27
Q

3 unique feaatures of cervical vertebra

A
  1. transverse foramen (raymon)
  2. Bifid tips
  3. overlapping bodies
28
Q

each vertebrae have a _ in the transverse process; they have 3 foramen that run vertically

A

transverse foramen

29
Q

The C2-C6 have short spinous processes the end in a

A

bifid tip

30
Q

the anterior endue of the cervical vertebrae is slightly more inferior than the posterior endg causing

A

slight overlap of the vertebral bodies

31
Q

the chunks of bone located between the superior and inferior articular processes are called the _. They are maned because they are larger and more supportive than the other vertebrae

A

articular processes

32

C1 doesn’t have a body, but a thick arch of bone called _ which contains an

A

anterior arch

anterior tubercle

35
Q

the _ ligament holds the dens or odontoid process in place

A

transverse atlantal ligament

36
Q

C1 has a _ w/ _ rather than laminae and a spinous process

A

posterior arch

posterior tubercle

37
Q

The superior articulating processes of C-1 have a large depressed surfaces for articulate with the occipital condyles of the skull;this articulation is called the

A

atlantooccipital articulation

38
Q

C-2 is also know as

A

Axis

39
Q

C-2 contains the _ or _ which projects up from the body
