A
Cervical: 7 
Thoracic: 13 
Lumbar: 7 
Sacral: 3 
Cd: variable
2
Q

Spinal cord column components

A
Cervical: 8 
Thoracic: 13 
Lumbar: 7 
Sacral: 3 
Cd: variable
3
Q

Which cervical vertebrae has a large transverse process?

A
  • C6
4
Q

Where is the first intervertebral disc?

A
  • Between C2 and C3
5
Q

Where do nerve roots exit in general?

A
  • lateral to the cord segment
6
Q

Where do nerve roots exit from C1?

A
  • Via lateral foramen of C1
7
Q

Where do nerve roots exit from C2-C8?

A
  • Cranial intervertebral foramen
8
Q

What do you use during ventral slot surgery to localize?

A
  • Large wings of C6
9
Q

For an atlanto-occipital tap, what is the landmark?

A
  • Use wings of atlas and spinous process of C2
10
Q

Thoracic spine characteristics

A
  • No transverse processes
  • They attach to the ribs
  • If you find one vertebra with a rib and one without, you know you’re at T13-L1
11
Q

Where do nerve roots exit in the thoracic spine?

A
  • Caudal intervertebral foramina (i.e. behind the corn segment
12
Q

How many cord segments in the thoracic spine, and where do they live relative to their respective vertebral body?

A
  • 13 cord segments, and each cord segment lives in its respective vertebral body (e.g. T3 cord segment is in the T3 vertebral canal)
13
Q

How can we distinguish T1 from C7?

A
  • Cranial vertebrae have prominent spinous processes
14
Q

How can we distinguish the T13-L1 junction?

A
  • Thoracic vertebrae have ribs, and lumbar vertebrae do not
15
Q

Where do the cord segments in the lumbar spine live relative to their respective lumbar vertebrae?

A
  • They don’t always line up
  • L2 aligns with L2 segment
  • L5 vertebral body has S1-3 segments
  • L3-L7 segments are in the L3 and L4 vertebral bodies
16
Q

What is in the vertebral canal after L5?

A
  • Cauda equine nerve roots
17
Q

What is the significance of a lesion localizing to L6-L7?

A
  • If you have a vertebral body lesion, you need to go more cranial than you might expect
18
Q

Other featurse of lumbar vertebrae that are unique?

A
  • Prominent articular processes

- Transverse processes that are fairly ventral on the body, and orient cranially

19
Q

Make sure you can identify the following:

  • Dorsal spinous process
  • Spinal cord
  • Articular process
  • Anulus fibrosus
  • Transverse process
  • Nucleus pulposus
A
  • Draw it out and know it
20
Q

Know the following:

Various parts of the vertebrae

Anatomy of the spinal cord relative to the vertebrae

  • Number of vertebrae in each of its segments
A
  • Just know it
21
Q

Compare and contrast the dorsal spinous process of cervical spine vs thoracic spine vs lumbar

A
  • Dorsal spinous process is quite short on the cervical spine
  • Very pronounced on the thoracic spine
  • Lumbar is kind of in-between?
22
Q

Label the following on the cervical spine:

  • Dorsal spinous process
  • Articular process
  • Transverse foramina
  • Transverse process
A

Just do it
