A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. When a person accidentally touches a hot object, they automatically jerk their hand away without thinking. A reflex does not require any thought input. The path taken by the nerve impulses in a reflex is called a reflex arc.
reaction time associated with repetitive fixed interval stimuli in a given stimulus-response situation usually decreases over a short time period to some minimal value and then remain the stable. explain.
voluntary reaction= is a willful and controllable response to stimulus. reflex response= is an involuntary reaction or autonomic programed response to a sensory stimulus. reaction time using a dominant, voluntary motor pathway is usually shorter than when using an equivalent non- dominant pathway. explain.
The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. It is polysynaptic, and causes the stimulation of sensory, association, and motor neurons.
explain the difference between voluntary reaction to a stimulus and a reflex response to a stimulus. volunt ary reaction= is a willful and controllable response to stimulus. reflex response= is an involuntary reaction or autonomic programed response to a sensory stimulus. reaction time using a dominant, voluntary motor pathway is usually shorter ...
the jendrassik maneuver decreases cerebral cortex awareness of muscle reflex activity, thereby reducing direct supraspinal descending inhibition of the alpha motor neurons.
ipsilateral reflex= if all components of a reflex pathway are located on one side right or left of the body, the reflex. contralateral reflex= if the sensory input occurs on one side of the body, and the motor out put and effector response occur on the other side of the body. define reciprocal inhibition. and explain its importance.
