BiologyCoordination and controlGCSEAQA Created by: Esme PearseCreated on: 08-05-16 09:43 electrical impulses used my the nervous system to enable you to react quickly to your surroundings and coordinate what you do 1 of 14 receptors these detect stimuli 2 of 14 stimuli changes in the environment 3 of 14 receptor cells e.g light receptor cells are like what other cell? animal cells, they have a nucleus cytoplasm and cell membrane 4 of 14 neurons impulses pass along these they are usually found in large quantitys known as nerves 5 of 14 CNS central nervous system, is made up of the brain and the spinal cord 6 of 14 sensory neurons these are cells which carry impulses from your sense organs to your CNS 7 of 14 motor neurons carry impulses to the right parts of your body 8 of 14 effector organs these respond to the impulses such as muscles contracting and glands secreting chemicals 9 of 14 define reflex actions automatic responses to stimuli 10 of 14 relay neurons connect a sensory and motor neuron in the CNS 11 of 14 what is included in a reflex arc sensory receptor, sensory neuron, relay neuron, motor neuron and effector organ 12 of 14 define synapse a gap between neurons where the transmission of information is chemical rather than electrical 13 of 14 reflex actions stimulus-->receptor-->coordinator-->effector-->response 14 of 14
