Part A What is an inhibitory neurotransmitter? Inhibitory neurotransmitters, like GABA, decrease the activity of the receptors, stimulating the ability of nerve cells to send signals to nearby norve cells. Inhibitory neurotransmitters, like GABA, increase the activity of the receptors, stimulating the ability of nerve cells to send signals to nearby nerve cells. Inhibitory neurotransmitters, like GABA, decrease the activity of the receptors, inhibiting the ability of nerve cells to send signals to nearby nerve cells. None of the above Submit Request Answer

You studied how neurotransmitter act and their use in medicine. Based on the information answer how Tetrahydrocannabinol, the active ingredient in marijuana, will binds to receptors located in the ________ terminals of certain brain neurons and lowers the likelihood that these neurons will release ________. options: postsynaptic, neurotransmitters presynaptic, neurotransmitters presynaptic, Ca2+ ions postsynaptic, Ca2+ ions
________ "mimic" or enhance the action of certain neurotransmitters. Select an answer from the options below Myelinated axons Antagonist drugs Endorphin drugs Agonist drugs
If a person is given an experimental drug, which response would indicate that this drug is an norepinephrine/epinephrine agonist? decreased blood pressure pupil constriction constriction of respiratory airways high blood sugar (hyperglycemia) decreased heart rate
Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.
Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the reasons why action potentials do not occur when these channels are inhibited.
Caffeine and nicotine have excitatory effects because they: reduce the threshold for excitation increase the threshold for excitation open potassium ion leakage channels open chemically-gated chloride ion channels close chemically-gated calcium ion channels ( explain deeply with step by step type the answer).
Explain the effects plant chemicals have on people (not just how it changes the way the neurotransmitter works, what does that change do to the person) if they affect PNS neurotransmitters in the following ways: Norepinepherine agonist Norepinepherine antagonist Acetylcholine agonist Acetylcholine antagonist Pick TWO of these, write down the neurotransmitter, then the effect a drug would have on people when doing what is listed in the bullet list.
Amplification of a chemical signal occurs when? a. phosphorylation of proteins by protein kinase receptors is balanced by the immediate removal of phosphate groups by phosphatases b. a receptor in the plasma membrane activates several “first messenger” molecules while a signal molecule is bound to it c. a cAMP molecule activates one protein kinase molecule before being converted to AMP d. a receptor activates a single first messenger and a single second messenger
Compare and contrast the receptors and signalling cascade, and the physiological roles for two neurotransmitters in the brain. I need to write 500 words on this question. Can you please help me with this question and can you aslo please send me the reference of the answer.
