receptor site of stimulus
sensory neuron transmits impulses to CNS
integration center synapses in the CNS
motor neuron transmits impulses to an effector organ
effector responds to the efferent impulses

parasympathetic digest and rest
somatic reflexes patellar reflex, achilles reflex
autonomic reflexes pupillary, salivary
exteroceptors react to external stimuli ex. Pacinian corpuscles
interoceptors react to internal stimuli ex. chemoreceptors
proprioceptors react to skeletal muscle stimuli ex. muscle spindles
Merkel discs light tough receptors (epidermis)
Meissner's Corpuscles respond to light touch (dermal papillae)
Pacinian Corpuscles high frequency vibration (reticular layer)
proprioreceptors muscle spindles
somatic skeletal muscles, voluntary
autonomic smooth muscle (cardiac muscles), involuntary
