L1-S3 spinal nerves

6

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

7

What is the caudal end of the spinal cord called?

Conus medullaris

What is the name given to the nerve roots below L1?

Cauda equina

11

What is he continuation of pia mater below the onus medullaris called?

Filum ferminale internum

12

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

Typically S2, the dural cut de sac

13

Neural tissue has been IDed in what part of the filum terminale?

Proximal part of the filum terminale internum

Tethered cord syndrome

19

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 caused by tethered cord
