Posterior inferior (PICA) Anterior Inferior (AICA) Superior Cerebellar
3 meninges that protects the Spinal Cord
Dura

PIA
golden period for the spinal cord until irreversible damage occurs
2 hours
Terminal portion of the spinal cord
Conus Medullaris
Firbrous extension of the PIA mater
Phylum terminale
Collection of nerve roots at the inferior end of the vertebral column
Cauda Equina
2 major blood vessels of the SC
2 posterior - 1/3 of the cord
1 anterior 2/3 of the cord
Reinforces the anterior and posterior spinal arteries
