New cards
Which cervical vertebrae are considered typical cervical vertebrae?
C3–C6
2
New cards
Which cervical vertebra is known as the atlas?
C1
3
New cards
Which cervical vertebra is known as the axis?
C2
4
New cards
Which cervical vertebra contains the dens, or odontoid process?
C2, the axis
5
New cards
What is the function of the dens of C2?
It acts as a pivot that allows C1 and the head to rotate
6
New cards
Which cervical vertebra is known as vertebra prominens?
C7
7
New cards
What feature gives C7 the name vertebra prominens?
A long, prominent spinous process
8
New cards
Which portion of a vertebra is the large anterior weight-bearing structure?
Vertebral body
9
New cards
Which structure forms a short bridge between the vertebral body and the posterior elements?
Pedicle
10
New cards
Which structure forms the plate of bone between the transverse process and spinous process?
Lamina
11
New cards
Which vertebral structure projects posteriorly from the vertebral arch?
Spinous process
12
New cards
Which vertebral structures project laterally from each side of the vertebra?
Transverse processes
13
New cards
Which large central opening in a vertebra transmits the spinal cord?
Vertebral foramen
14
New cards
Which opening within the transverse process of a cervical vertebra transmits vertebral vessels?
Transverse foramen
15
New cards
Which opening between adjacent vertebrae allows spinal nerves to exit the vertebral column?
Intervertebral foramen
16
New cards
How is an intervertebral foramen formed?
The superior and inferior vertebral notches of adjacent pedicles join to form the opening
17
New cards
What is a facet?
A smooth articular surface on a bone
18
New cards
Which facet articulates with the vertebra above?
Superior articular facet
19
New cards
Which facet articulates with the vertebra below?
Inferior articular facet
20
New cards
What joint is formed when the articular facets of adjacent vertebrae meet?
Zygapophyseal joint
21
New cards
What is the difference between a facet and a zygapophyseal joint?
A facet is one smooth articular surface; opposing facets of adjacent vertebrae form a zygapophyseal joint
22
New cards
What is a bifid spinous process?
A split spinous process commonly seen in C3–C6
23
New cards
Which cervical vertebra lacks a typical vertebral body?
C1, the atlas
24
New cards
Which structure replaces a true spinous process on C1?
Posterior tubercle
25
New cards
What structures form the ring of C1?
Anterior arch and posterior arch
26
New cards
Which C1 articular facets articulate with the occipital condyles?
Superior articular facets
27
New cards
Which C1 articular facets articulate with C2?
Inferior articular facets
28
New cards
What is the major distinguishing feature of C1 compared with a typical cervical vertebra?
C1 is ring-shaped and lacks a typical body and true spinous process
29
New cards
What is the major distinguishing feature of C2?
The dens, or odontoid process
