WebThe reflex arc consists of a sensory neuron that responds to the stretch of a muscle, and a motor neuron that in turn causes muscle contraction. In general, if only one limb is … WebThe all or none action potential is then propagated by the conductive components. The action potential will reach the terminal and then will stimulate release of neurotransmitters. The neurotransmitter will then bind to receptors on the postsynaptic cell. The stretch reflex pathway illustrates how neural signals are changed from sensory to motor.
