Spinal Cord Flashcards
in horizontal view, what direction of the spinal cord tends to be largest
transverse
What are the spinal cord enlargement locations and the name given to each
C3-T1 cervical enlargement
T9-T12 lumbar enlargement
Where is the greatest transverse diameter of the spinal cord
C6
in which plane or direction will the diameter of the spinal cord decrease from C2 to T1
midsagittal or anterior-posterior plane
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
What is the caudal end of the spinal cord called
Conus medullaris
What spinal nerves originate from the conus medullaris
typically S4 S5 and Co1
in which vertebral foramen will the conus medullaris typically be observed
L1
What is the name given to the nerve roots below L1
Cauda Equina
What is the continuation of pia mater below the conus medullaris called
filum terminale internum
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
neural tissue has been identified in what part of the filum terminale
proximal part of the filum terminale internum
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
What is the name given to the caudal attachment of the meninges
coccygeal medullary vestige
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
