Question 6

paragraph of reflex arc summary

Answer 6

receptors in the skin detect the stimulus an electrical impulse travels through sensory neurone to the spinal cord (the relay neurone). electrical impulses go from the dendron to the axon connecting to the next neurone through dendrites (claw thing) and eventually to the effector( the muscle) which will initiate the response in order to reflect what caused the initial trigger
