Flashcards in Spinal Cord Deck (16):
1

in horizontal view, what direction of the spinal cord tends to be largest

transverse

2

What are the spinal cord enlargement locations and the name given to each

C3-T1 cervical enlargement
T9-T12 lumbar enlargement

3

Where is the greatest transverse diameter of the spinal cord

C6

4

in which plane or direction will the diameter of the spinal cord decrease from C2 to T1

midsagittal or anterior-posterior plane

5

What is a generic cord level of origin-vertebral level combination for the lumbar enlargement

L1,L2 cord levels in T9 vertebra
L3,L4 cord levels in T10 vertebra
L5,S1 cord levels in T11 vertebra
S2,S3 cord levels in T12 vertebra

6

What is the caudal end of the spinal cord called

Conus medullaris

7

What spinal nerves originate from the conus medullaris

typically S4 S5 and Co1

8

in which vertebral foramen will the conus medullaris typically be observed

L1

9

What is the name given to the nerve roots below L1

Cauda Equina

10

What is the continuation of pia mater below the conus medullaris called

filum terminale internum

11

What is the location and the name given to the area where all meninges first converge at the caudal part of the vertebral column

Typically S2, the dural cul de sac

12

neural tissue has been identified in what part of the filum terminale

proximal part of the filum terminale internum

13

What is the fate of the neural tissue identified along the filum terminale internum

it joins peripheral nerve roots of spinal nerves as high as L3 and as low as S4

14

What is the name given to the caudal attachment of the meninges

coccygeal medullary vestige

15

What is the name given to the condition in which the conus medullaris is located below L1 and the filum terminale is thickened

tethered cord syndrome

16

What is the relationship between scoliosis and tethered cord syndrome

it is suggested that the column will change normal curvatures to mitigate damage to the spinal cord
