Receptors in the sensory organs detect the stimulus (i.e skin, nose, ears, tongue , eyes) 2 of 7 Describe stage THREE in the reflex arc. There are SEVEN stages. Impulses sent to SENSORY neurone through the stimulus 3 of 7 Describe stage FOUR of the reflex arc. There are SEVEN stages impulses sent to RELAY neurone via chemical secreted across the SYNAPSE 4 of 7 Describe stage FIVE of the reflex arc. There are SEVEN stages. Impulses travel along the MOTOR neurone via the SYNAPSE 5 of 7 Describe stage SIX of the reflex arc. There are SEVEN stages. Effectors in the body (.ie a muscle contracting) stimulate a response 6 of 7 Describe stage SEVEN of the reflex arc.
