Cervical Vertebrae

Question 1

The two functional groups of the cervical vertebrae are sub occipital and inferior. Describe the movements of these regions?

Answer 1

Suboccipital (C1 and 2)
- rotation, flexion and extension
Inferior (c3-c6)- flexion, extension and lateral flexion

Question 2

A typical cervical vertebrae (C3-6) is small and flattened. Describe the joint of lushka found in this typical C vertebrae?

Answer 2

also named uncovertebral joint

• the uncinate processes is on the superior lateral surface of the body
• semilunar facets are on inferior lateral surface of body.
• the joint allows limited lateral flexion with some rotation.
• guides movements in flexion and extension

Question 3

What is there a large triangular vetebral foremen at C3-C6 compared to the rest of the C vertebrae?

Answer 3

spinal cord is large here

Question 4

The typical C vertebrae has articular pillar consist of ?

Answer 4

SAP, IAP and pars interarticularis in vertical line.

Question 5

Describe the SAP of the Typical C vertebrae?

Answer 5

flat and oval

faces superior, posterior and slightly medial= oblique plane/

Question 6

Describe the IAP of the typical C vertebrae?

Answer 6

flat and oval

faces inferior, posterior and slightly lateral

Question 7

The C vertebrae has the transverse process that are short and bifid that allows attachment of deep neck muscles. What else is unique about the TP of a typical C vertebrae?

Answer 7

1.anterior tubercle = costal surface
2. posterior tubercle= true transverse process
groove/gutter for spinal nerves.

Question 8

All C vertebrae has transverse foremen. What is the purpose of this?

Answer 8

C1-6: transmit vertebral artery and veins

C7: transmits only vertebral veins not artery

Question 9

Describe the intervertebral foramen?

Answer 9

• Between the sup and inf vetebral notches
• bordered by intervertebral discs, adjacent vertebral bodies, joint of luchska, adjacent pedicles and zygapophyseal joint.
• directed obliquely to

Question 10

Where does the first IVF start on the vetebral column?

Answer 10

C3 –> C7 and T1

because the ociput and C1, C1–C2 has a intervertebral sulcus for the nerves instead.

Question 11

What are the unique characteristics of atlas (C1) ?

Answer 11

no body instead there is anterior and posterior arch, no pedicles, no laminae, no spinous process.

• Has large lateral masses that has Tps, SAP and IAP extending from.
• it is the widest vertebrae in the neck.
