Document Summary
Psychoactive drugs: drugs that influence subjective experience and behavior by acting on the nervous system. Agonists: increase or facilitate activity, up communication, if record on postsynaptic gap, increase communication on particular synapses that fit this key (the neurotransmitter that fit, agonize the system increase the communication in the nerve system. Identification sites if neurotransmitters attaches to it, the receptor changes the shape, ions flowing in released, flow back agonists. Botox blocks the neurotransmitters: reuptake inhibitors block the reuptake and have the neurotransmitters hang in the synapses. Absorption through mucous membranes: nose, mouth, rectum. Absorption: must pass the blood-brain barrier in order for a psychoactive drug to have an effect (cuz it must get to the brain) How much the drug is in your system, and it will show in a curve. Give them sinboxin orally so that they can to last longer but not as strong.
