Flashcards in Spinal Chord Deck (14):
1

Erector Spine Muscles 3

Illocostalis thoracis(high)/lumborum (low)-most distil

Longassicis thoracis-2nd most medial

Spinalis-most medial

2

Vertebral canal

Under lamina

3

Ligamentum flava

Under laminae
-extends between and covers dura mater/sac

4

Dura mater and dura sac functions

Dura mater covers the dura sac

5

Epidural space

Space between dura mater and bony vertebral arch

6

Spinal gangia

coming out laterally of dura mater

fat part

7

Arachnoid

Under the dura mater

Usually fluid filled and pushed up against dura mater-collapsed in disection

Covers the surface of the spinal chord

8

Conus medullaris

tapering inferior end of spinal chord

9

cauda equina

composed of both dorsal and ventral roots

roughly around after l5

10

Dorsal and ventral roots

coming off the dural sac

11

denticulate ligament

separates dorsal and ventral roots as they leave dural sac

12

Spinal nerve

under arachnoid

13

dorsal root ganglion

i think this is same as spinal gangion

14

Ventral ramus and dorsal ramus

what do these come from

ventral is the large branch and smaller branch is the dorsal ramii

dorsal root ganglia divides into these
