Test Flashcards
(30 cards)
White matter main function
Communication between cells
Gray matter nuclei
Cluster of synaptic connections and nerve cell bodies
Gray matter main function
Thinking
Gray matter metabolism
“grayter” demand for blood flow because of high metabolic requirements
Choroid plexus
Produces CSF, within ventricles of the brain
Where are cranial nerve nuclei housed?
Brain stem
Internal carotid artery
Supplies anterior circle of Willis
Vertebral artery
Supplies posterior circle of Willis
Watershed areas
Distal portion of perfusion areas, where regions meet. Most sensitive to ischemia
Anterior Cerebral Artery, ACA
Lower extremity sensory motor function
Middle cerebral artey
Upper extremity and face sensory motor function
Where does the spinal cord end?
Medulla down to L2
Conus medulla rid
Tapered end of spinal cord
Cause equine
Nerve roots extended from the conus
Film terminals
Connects spinal cord to coccyx; non neural connective tissue
Dorsal nerve root
Incoming sensory fibers
Central nerve root
Outgoing motor fibers
Dorsal root ganglion
Houses sensory cell bodies; within dorsal nerve root
Farcicalus gracious
Lower SSEP
Fasciculus Cuneatus
Upper SSEP
Lateral Corticospinal
TCMEP
Posterior spinal arteries
(2) blood supply to superior 1/3
Anterior spinal artery
(1) blood supply to anterior 2/3 of spinal cord
Artery of Adamkiewicz
Major supplier of spinal cord, located ~T10 (low thoracic level)
