New cards

sensory pathway

info originates at receptors in periphery
info ascends on axons of sensory neuron in white matter of spinal cord
info is relayed to cell bodies of gray matter in cerebral cortex

2
New cards

motor pathway

originate in cell bodies of motor neurons in gray matter of cerebral cortex

info descends on axons of motor neurons in white matter of spinal chord

info relayed to cell bodies of gray matter whose axons carry info to skeletal muscles 

3

yes but eventually reach consciousness

4
New cards
