C-Spine Flashcards
What cervical vertebrae’s are typical?
3-6
-small and wide side to side
The lateral margins on the superior surface are upturned and articulate with the one above
Unicinate
*3-6
T/F
The transverse processes of the cervical vertebrae have foramen called the foramen transversarium for vessels
True
What is the difference between the spinous processes on the cervical vertebrae (3-6)?
Short and bifid
What is the direction of the intervertebral foramina of the cervical vertebrae (3-6)
Face forward and put on 45 degree angle
Columns of bone that project laterally from the junction of the pedicle and lamina
Articular pillars
What creates the articular pillars?
The superior and inferior articular processes of cervical vertebrae have fused on either side
The hook shaped process, or bony perturbance located on the lateral or posterolateral margins of the superior endplates of the cervical vertebral bodies
Most commonly found at the levels of C3-C7
Uncinate processes
-supports the head
-has no body and no spinous process
-shaped like a ring
-consists of anterior and posterior arch and 2 lateral masses
Atlas C1
The smaller part of the atlas C1, has an anterior tubercle on the anterior surface and a small facet on the posterior surface for articulation with the odontoid of C2
Anterior arch
The largest part of the atlas C1, also has a posterior tubercle
Posterior arch
What shape are the superior lateral masses of the atlas C1?
Oval, Concave and articulate with occipital condyles of the skull
What are the joints called where the superior lateral masses of atlas C1 articulate with the occipital condyles of the skull
Atlanto-occipital joints
What shape are the inferior lateral masses of atlas C1?
Round, flat and articulate with the superior facets of C2
T/F
The transverse process of Atlas C1 have a hold called the foramen transversarium and are longer than the other cervical vertebrae
True
How many articulating surfaces are on Atlas C1?
5
How many joints include Atlas C1?
3
-atlanto-occipital
-articulation with odontoid of C2
-joint between inferior masses of C1 and superior masses of C2
What does the Axis C2 consist of?
Body and vertebral arch
What projects up from the body of Axis C2?
Odontoid
What does the odontoid articulate with?
The posterior surface of the anterior arch of Atlas C1
*held in place by the transverse ligament of Atlas C1
What type of joint is formed at the odontoid?
Pivot joint
T/F
The spinous process of the axis C2 is large and bifid
True
T/F
The transverse processes of Axis C2 are small
True
Where are the superior articular facets located on the Axis C2?
Lateral part of the body
*articulate with the inferior lateral masses of Atlas C1
What is different about C7?
It has a prominent spinous process which is easily palpable
*vertebra prominens
T/F
The transverse process of C7 are large and could possibly develop as a cervical rib
True
T/F
The foramen transversarium of C7 is small, and may even be absent
True
