Nervous System - Communication Network
Threshold - Minimum stimulus that just produces a response
Reflex - A relatively simple, involuntary response to a stimulus.
Reflex Arc - the circuit that supports or makes possible the reflex action. Most basic
neural pathway.
stretch reflex - the contraction of a muscle in response to stretch of that muscle
latent period - time between application of a stimulus and the beginning of a response in
a muscle fiber
plantar reflex - elicited touching the soles of the feet. toes curl downward. (birth to 8
months)
knee jerk reflex - a variant of the stretch reflex in which stretching of the tendon beneath
the knee leads to an upward kick of the leg
Component parts of the knee-jerk reflex arc - muscle spindle (sensory receptor), sensory
neuron, motor neuron, skeletal muscle (effector)
sensory receptors - receive physical or chemical stimulation (changes in the environment)
Proprioceptive - information about body position
adequate stimulus - Stimulus of the proper quality; capable of evoking a response if of
sufficient strength
acuity - discriminative ability
