Flashcards in Neuroanatomy Deck (14):
1

Fluid filled cavity located in the middle of the transverse span of gray matter in spinal cord?

central canal.

2

groove between dorsal column?

dorsal median sulcus

3

Rules for differentiating cervical from thoracic from lumbar vertebrae?

1) Present of lateral horn = T1-L2.
2) Greatest amount of grey matter is in cervical and lumbosacral enlargements (massive innervation)
3) Fasiculi cuneatus and gracilis are BOTH present above T7.
4) cervical vs. lumbosacral enlargement = dorsal horn is narrower at cervical levels than in lumbars.

Trick about cranial nerves

CNVII has 2 little paired segments

9

What will MLF syndrome produce?

1) medial rectus palsy on lateral conjugate gaze.
2) *convergence is normal.
3) Abducting eye gets nystagmus (CN VI overtires to stimulate CN III).
