infoWhy this? Receptors and nervous control explain how stimuli are detected, encoded as electrical signals, and translated into rapid, coordinated responses. Connecting receptor function, nerve impulses, and synapses helps us understand reflexes, sensory responses, and the effects of drugs or disease on communication within the body.

scheduleWhy now? Earlier work on membrane transport, ions, ATP, and respiration provides the mechanisms needed to explain resting potentials, action potentials, and synaptic transmission. Introducing nervous coordination before homeostasis and muscles allows us to connect detection and signalling with regulation and contraction.
