Which of the following is an effect of cocaine and amphetamine? Group of answer choices Blocking dopamine reuptake Activating acetylcholine receptors on VTA neurons Directly activating dopamine receptors Inhibiting GABA release from interneurons All of the above
Drugs that have been developed to potentiate inhibitory neurotransmitters (like gamma amino butyric acid and glycine) include all of the following except: tranquilizers tacrine ethanol valium barbiturates
Reserpine is a drug that can control high blood pressure by reducing the number of catecholamine neurotransmitters present in the synapse. Epinephrine, norepinephrine, and dopamine are examples of catecholamine neurotransmitters. One of the known side effects of reserpine is to cause the symptoms of Parkinson’s disease. Parkinson's disease is associated with dopamine. Parkinson's disease occurs when the nerve cells in the part of the brain that controls muscle movement are gradually destroyed and the neurons can no longer produce dopamine to coordinate muscle movements. Reserpine causes symptoms by a. inhibiting the release of dopamine from the presynaptic neuron b. blocking the dopamine receptor in the postsynaptic neuron c. breaking down the neurotransmitter acetylcholine in the synapse d. breaking down cholinesterase enzyme in the synapse
Which of the following neurotransmitters serve as the body's natural painkiller? Acetylcholine Endorphins Dopamine
one way in which drugs can increase neurotransmitter release is by preventing conduction of action potential true false
A patient takes a stimulant that produces euphoria, as well as an increase in heart rate and blood pressure and it treats narcolepsy. To exert its effect, the drug must be taken up into nerve terminals, where it stimulates the release of norepinephrine and dopamine from their vascular storage sites.
Classify the following neurotransmitters as excitatory or inhibitory: Acetylcholine Serotonin GABA Norepinephrine Glutamate Dopamine
The drug Rohypnol ("roofies") acts as a sedative. What is the mechanism by which roofies act in the brain? A. Roofies act at the GABA receptor complex which opens a sodium channel B. Roofies act at the acetylcholine receptor C. Roofies act as a dopamine receptor agonist D. Roofies block the dopamine transporter E. Roofies act at the GABA receptor complex which opens a chloride channel
Many drugs work by interfering with the inactivation of neurotransmitters once they gave been released. What are the two basic mechanisms whereby a drug may interfere with this process? In under 5 sentences.
Parkinson's Disease Parkinson's disease is a neurological degenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain. Since most symptoms of Parkinson's disease are caused by insufficient dopamine in the brain, many Parkinson's drugs either temporarily replenish dopamine or mimic the action of dopamine. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. 1. List the steps involved in an action potential moving from the axon terminal of the pre-synaptic neuron to the dendrites of the post-synaptic neuron. 2. Explain how the process is different in individuals affected with Parkinson's disease.
Which of the following neurotransmitters is associatedwith inhibition exclusively?a. GABAb. acetylcholinec. glutamated. norepinephrine
