Two nerves are involved; one receives the stimulus and transmits the impulse to the spinal cord, and the other, a motor nerve, receives the impulse and relays it to the quadriceps muscle. Inadequate response to the knee jerk test may mean that the reflex mechanism involved is in some way ...
EFFECTS OF BRAINSTEM LESIONS ON THE MASSETER INHIBITORY REFLEX: FUNCTIONAL MECHANISMS OF REFLEX PATHWAYS The extent of the lesions was assessed by neurological examination, nuclear magnetic resonance imaging (MRI), and recording of trigeminal reflexes with known paths (jaw jerk and blink reflex). The...
