Action of Neurotransmitters Name: ____________________________________ Use the online reference “Neurotransmitter Chart page 1 and page 2” from the webpage to complete the following chart & questions. Follow through these questions to help you understand how neurotransmitters work. Acetylcholine (Ach) 1. This NT is _________________ to skeletal muscles. This means that when the NT is released, it will cause a signal to go to the muscles causing them to ________________. When the NT is removed from the synapse, the muscles will then __________________. 2. Nerve gas and organophosphate insecticides prolong the effects by leaving the NT in the receptors. This means the muscles will have continued ____________________________ causing seizure like activity. 3. Botulinus toxin (Botox) _____________________ the release of the NT causing the muscles to be unable to _____________________. Botox removes wrinkles by paralyzing the muscles. 4. Ach levels __________________________ in certain brain areas in Alzheimer’s disease. Explain briefly how this might affect the movements of someone with Alzheimers. Biogenic Amines 1. Norepinephrine - This NT is known as a “___________________________” NT. Its release is enhanced by amphetamines. What symptoms might this cause in a person under the influence of amphetamines? Circle ALL possible choices. a. b. c. d. e. Excitement Increased confidence Increased depression Lethargy Lower heart rate f. g. h. i. j. Pupil constriction Pupil dilation Raised pulse Restlessness Talkative 2. Dopamine - This NT is also known as a “___________________________” NT. a. Its reuptake (removal from synapse) is blocked by cocaine. What symptoms might this cause in a person under the influence of cocaine? Circle all possible choices. 1. Increased depression 7. Lethargy 2. Talkative 8. Pupil constriction 3. Unsocial behavior 9. Hypothermia 4. Hyperthermia 10. Increased confidence 5. Pupil dilation 11. Decreased sensation of 6. Inability to sit still pain b. It is deficient in someone with Parkinson’s disease? What might this deficit cause? Circle all possible choices. 1. Increased depression 5. Inability to sit still 2. Talkative 6. Euphoria 3. Stiff, achy muscles 7. Increased confidence 4. Soft monotonous speech 8. Fearful 3. Serotonin – This NT is blocked in someone under the influence of LSD. List 3 possible symptoms this might cause in someone under the influence of LSD. a. ____________________________________________________________________ b. ____________________________________________________________________ c. ____________________________________________________________________ Amino Acids 1. GABA – principal ______________________ neurotransmitter in brain. These effects are augmented by alcohol and anti-anxiety medicine. a. What does this word mean? ________________________________________________. b. What types of inhibitory effects can be seen in a person under the influence of alcohol? List 3 symptoms/effects. i. ____________________________________________________________________ ii. ____________________________________________________________________ iii. ____________________________________________________________________ 2. Glycine – Strychnine ___________________ glycine receptors. This means that glycine cannot bind to the receptors and so will have no effect. Glycine is generally ______________________________ in action so, when blocked, muscles cannot relax which leads to __________________________________________________ and __________________________________________________. Peptides 1. Endorphins – Natural _____________________. a. What is morphine used for in medicine? _________________________________ b. Would a police officer have trouble subduing someone who is under the influence of heroin? Explain your answer.
