reflex are rapid involuntary motor responses the name of the reflex tells us where they occur and what job *a somatic reflex is a contraction of the skeletal muscle, * if the motor response involves the response of smooth muscle cardio muscle or glands it is automatic (visceral) reflex |

Term
describe the difference between ipsilateral and contralateral reflex arc |
|
Definition
reflex arcs involve sensory receptors, sensory nerve fibers, motor neurons and effectors---- ipsilateral occur only on one side of the body... whereas contralateral occur on one side of the body with the exception of motor neurons and effectors occuring on the opposite side |
