1 of 11
What is the Central Nervous System (CNS)
Brain and Spinal Cord
2 of 11
What is the sequence from Stimulus to Response?
Stimulus, Receptor, Sensory neuron, Central nervous system, Motor neuron, Effector, Response
3 of 11
What does the Peripheral Nervous System consist of?
Motor and Sensory Neurons
4 of 11
What three neurons are in the Reflex arc?
Sensory neuron, Motor neuron, Relay neuron
5 of 11
What is serotonin and example of ?
A neurotransmitter.
6 of 11
What happens in a Synapse?
An impulse is carried along an axon up to the synapse, The synapse releases neurotransmitters specfic to the impulse, The neurotransmitters bind with receptors on the post-synaptic neuron, The impulse continues through the neuron.
7 of 11
What are re-uptake channels?
Re-uptake channels take the remaining neurotransmitters so not too much is given.
8 of 11
How does Prozac affect Synapses?
Blocks re-uptake channels to serotonin cannot be removed from the synapse.
9 of 11
How does ecstasy affect synapses?
Ecstacy blocks the receptors on the post synaptic neuron, This increases the levels of serotonin in the synapse resulting in good feelings.
