1 Stimulus Detection: Sensory receptors detect stimuli (e.g., touch, heat). 2 Signal Transmission: Sensory neurons transmit signals from receptors to the brain and spinal cord. 3 Processing: The brain and spinal cord process the information, deciding on a response. 4 Response Transmission: Motor neurons carry signals from the brain and spinal cord to muscles or glands. 5 Action: Muscles contract or glands secrete, creating a response. |
The nervous system uses neurotransmitters at synapses to transmit signals between neurons.
