Welcome to your Human Nervous System Name Email An insect flies near a person’s eye. The person blinks. This is a reflex action. Figure 2 shows the coordination system for this reflex action. Use the words to answer the following questionsWord: brain, cornea, iris, muscles and retina2 3 4 Match the following to their defination Effector Receptor reflex action Sensory neurone Motor neurone automatic response reaction sends electrical impulses to an effector detects stimulus produces a response sends electrical impulses to relay neurone, which are located in the spinal cord Fill in the blank space. Describe how electrical impulses move through synapse. An electrical impulse travels along the first axon.This triggers the nerve-ending of a neurone to release chemical messengers called 1) These chemicals 2) across the synapse (the gap) and bind with receptor molecules on the membrane of the second neurone.The receptor molecules on the second neurone bind only to the specificneurotransmitters released from the first neurone. This 3) the second neurone to transmit the 4) . Match the stimulus to the sense organs sound Light touch taste Tongue eye ear skin Name the following neurones A) neuronesB) neuronesc) neurones What is the function of the following neurones Fill the blank spaces1) neurone A conducts impulses to 2)neurone B conducts impulses to 3)neurone C conducts impulses to 1 out of 6 Time's upYou cannot switch tabs while taking this quiz!You are not allowed to switch tabs violation has been recorded.you cannot minimize full screen mode!You are not allowed to minimize full screen while taking this quiz, violation has been recorded.Access denied!
