- Stimulus
- Behaviour terms
- Stimulus: A change in the
environment (external or internal)
that is detected by a receptor
- Response: A change in an
organism resulting from a stimulus
- Reflex: A type of response
that is rapid and involuntary
- Stimulus response
- Receptors transform stimuli
into electicalnerve impulses
- Sensory neurons relay the nerve
impulse to the CNS (via the dorsal root)
- Relay neurons transmit nerve
impulses within the CNS
- Motor neurons transmit nerve impulses from
the CNS and relays the signal to an effector
- Effectors (muscles or glands)
produce a response to the stimulus
- Synapses are junctions between nerve
cells across which neurotransmitters pass.
- The stimulus response model
- Stimulus-->receptor-->sensory neuron-->CNS-->
relay neuron-->CNS-->effector-->response
- Perception
- types of receptors
- Light: photoreceptors
- Movement: mechamoreceptors
- Temp: thermoreceptors
- Chemicals: chemoreceptors
- Pressure: baroreceptor
- Pain: nocireceptors
- Position: proprioceptors
