what is the role of the cns
sends messages to the rest of the body via the spinal cord, in the form of nerve impulses.
what is further detail on nerve impulses and the role of the CNS
nerve impulses travel along the neuron where it diffuses from the presynaptic neurone over the synaptic cleft to the post synaptic neuron
what does the cns include
the spinal coard and brain
what are two key recreational drugs
canabis and alchahol
how does canabis work
blocks receptors on post synaptic neurone by mimicing the neurotransmitters.
what does alchahol do
blocks reuptake pump increasing seretonin. also increases GABA
evaluate the role of neurotransmitters and the cns on agression - give for AO1 POINTS
ao1- the cns is responsible for sending messages in the form of nervous impulses around the bodys nervous system, from the brain through the spinal coard ao1- impulses travel along the neurone frm the post synaptic neurone diffuse through synaptic cleft into the post-synaptic neuron where it uis taken up by receptors ao1- one neurotranssmiter that could affects agression is seretonin. increase in seretonin can lead to increase agression and volitile nature ao1- brain damage - dmage to the brain can affects pfc
