CNS and recreational drugs

Question 1

what is the role of the cns

Answer 1

sends messages to the rest of the body via the spinal cord, in the form of nerve impulses.

Question 2

what is further detail on nerve impulses and the role of the CNS

Answer 2

nerve impulses travel along the neuron where it diffuses from the presynaptic neurone over the synaptic cleft to the post synaptic neuron

Question 3

what does the cns include

Answer 3

the spinal coard and brain

Question 4

what are two key recreational drugs

Answer 4

canabis and alchahol

Question 5

how does canabis work

Answer 5

blocks receptors on post synaptic neurone by mimicing the neurotransmitters.

Question 6

what does alchahol do

Answer 6

blocks reuptake pump increasing seretonin. also increases GABA

Question 7

evaluate the role of neurotransmitters and the cns on agression - give for AO1 POINTS

Answer 7

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
