List the primary sensations mediated by the 2 major sensory pathways of the CNS.
Spinothalamic tract: mediates pain, temperature, and crude or light touch (not precisely localized). ( lateral spinothalamic tract = pain, temperature) (anterior spinothalamic tract = crude touch)
Posterior dorsal columns = sensation of position, vibration and fine, localized touch (identify objects by touch)
Describe 3 major motor pathways in the CNS including the type of movements mediated by each.
Corticospinal/pyramidal tract = “higher” motor system for purposeful and skilled movements (writing)
Extrapyramidal tract = “lower” or primitive movements
Cerebellar system = coordinates movements, maintains equilibrium and helps maintain posture
Differentiate an upper motor neuron from a lower motor neuron.
Upper = located in CNS and are the descending fibers that influence/modify the lower motor neurons. convey impulses from the cerebral cortex to the lower.
Lower = located in the PNS cell body in gray matter of spinal cord, nerve fiber extends to directly connect to the muscles (the final common pathway).
