A stimulus is detected by a receptor, which is a senseorgan. The electrical impulse travels down the sensory neurone to the centralnervous system, the spinal cord or the unconscious part of the brain. At asynapse between the sensory neurone and the relay neurone, the electricalimpulse diffuses across the gap in the form of a chemical substance. When thechemical substance reaches the relay neurone, it triggers another electricalimpulse to be sent. The same thing happens between the relay neurone and themotor neurone, and then an electrical impulse is sent along the motor neuroneto the effector. The effector is either a muscle (which contracts to bringabout movement) or a gland (which secretes hormones) which brings about a response.do you agree with this part in bold? sorry for so many questions, just want to make sure as it could be a 6 marker
