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
