WebReflex action is an involuntary response to a stimulus that is manifested at the level of the spinal cord. The pathway followed by a nerve impulse during this action is called the reflex arc. The components of a reflex arc are; A receptor to detect the stimulus. A sensory neuron to carry the information towards the spinal cord.
WebKnee Jerk Reflex A normal knee jerk indicates that a number of neural and muscular components are functioning normally. The stretch reflex is monosynaptic, because there is only 1 synapse in the loop (between the spindle afferent and the alpha motor neuron). The reciprocal inhibition pathway is polysynaptic because it involves interneurons.
