2.88: Understand that Stimulation of Receptors in Sense Organs Sends Electrical Impulses Along Nerves Into and Out of the Central Nervous System, Resulting in Rapid Responses

COORDINATED RESPONSE: Process in which a reaction is carried out in response to a change in environment (stimuli)

COORDINATED (RAPID) RESPONSE

Diagram showing the Process of Rapid Responses

PROCESS: Stimuli is detected by receptors, stimulating Sensory Neurons that send electrical impulses to the Central Nervous System (CNS) - Brain and Spinal cord Central Nervous System relays impulse across the synpase (gaps between Neurones) to Relay Neurons via synaptic transmission Relay Neurons relays impulse to Motor Neurons in the Effector, which will quickly carry out rapid response
