different segments of myelin slides

This is a rough estimate of what the myelin slides should be:

1) Sacral level – spinal cord
2) Lumbar level – spinal cord
3) Thoracic level – spinal cord
4) C7 Lower cervical level – spinal cord
5) C1 cervical level – spinal cord
6) Lower medulla level
7) lower Medulla
8) medulla
9) Upper medulla area
10) upper medulla level
11) medulla-pons junction
12) dorsal medulla
13) dorsal pons
14) lower pons
15) lower pons
16) upper pons
17) rostral upper pons
18) pons-midbrain junction
19) lower midbrain
20) midbrain
21) upper midbrain
22) midbrain-dincephalon junction
