- Responses
- Central nervous system (CNS)
- Brain, Spinal Cord- through the neurones
- FAST RESPONSE!
- Brain, Spinal Cord- through the neurones
- Endocrine system
- Glands, Hormones-through the bloodstream
- SLOW-ER RESPONSE
- Glands, Hormones-through the bloodstream
- Voluntary/ concious response
- Stimulus- Object or change in environment that triggers response
- Receptor- in the sense organs. Stimulated by the stimulus.
- Sensory neurone- Carries electrical impulse to the CNS
- SYNAPSE TO A RELAY NEURONE
- Relay neurone- In the CNS where the response is coordinated
- SYNAPSE TO A MOTOR NEURONE
- Motor neurone- Carries electrical impulse from the CNS to the effector
- Effector- e.g. Muscle or gland that completes the decided response
- Response- as a result of the stimulus. The action that is completed
- Effector- e.g. Muscle or gland that completes the decided response
- Motor neurone- Carries electrical impulse from the CNS to the effector
- SYNAPSE TO A MOTOR NEURONE
- Relay neurone- In the CNS where the response is coordinated
- SYNAPSE TO A RELAY NEURONE
- Sensory neurone- Carries electrical impulse to the CNS
- Receptor- in the sense organs. Stimulated by the stimulus.
- Stimulus- Object or change in environment that triggers response
- SYNAPSE- Gaps between neurones- chemicals diffuse across the gap. Synapses are the slowest part of the response
- Involuntary response- Reflex actions are much faster than voluntary responses, because no decision is involved
- Stimulated receptor
- Sensory neurone
- Relay neurone in spinal cord
- motor neurone
- Effector
- motor neurone
- Relay neurone in spinal cord
- Sensory neurone
- Stimulated receptor
- Central nervous system (CNS)
- Brain, Spinal Cord- through the neurones
- FAST RESPONSE!
- Voluntary= Brain & Spinal Cord
- Involuntary= Brain or spinal cord (which ever is closest to the stimulus)
