- Dual innervation means that visceral effectors are innervated by preganglionic axons from both parasympathetic and sympathetic (ANS) divisions. A. True B FalseWhich of the following statements is true? Select one: O a. Cholinergic nicotinic receptors of autonomic ganglia are identical to N cholinergic receptors of neuromuscular junction O b. Some of the postganglionic sympathetic fibers are cholinergic O c. All of the visceral organs/structures have dual innervation (sympathetic and parasympathetic) O d. Adrenaline does not usually circulate in bloodWhich of the following could be used to describe Norepinephrine (NE)? Select all that apply. hormone neurotransmitter Secreted by most postganglionic parasympathetic fibers uses cholinergic receptors a beta blocker would decrease its activity Secreted by most postganglionic sympathetic fibers Next Drovious
- Match the following statements to the correct neurotransmitter of the autonomic nervous system. Select "Both" if the statement is true of both neurotransmitters. Secreted by cholinergic fibers. Receptors for this neurotransmitter may cause either excitatory or inhibitory responses. Bind(s) to adrenergic receptors. Receptors for this neurotransmitter are found on all autonomic postganglionic neurons. This neurotransmitter can increase heart rate. ANSWER OPTIONS: Acetylcholine or Norepinephrine? Both?Fentanyl is an opioid similar to morphine, except, according to the CDC, it is up to 50 times stronger than heroin and 100 times stronger than morphine. Discuss the effects of fentanyl on specific receptors and how the transmission of action potentials is altered. Be sure to focus only on how the action potential transmission is impacted by the drug. Be sure to provide an APA citation.draw and describe the working of a cholinergic nerve terminal and the receptors upon it, including any feedback mechanism.
- Malathion is an insecticide commonly used in the horticultural industry. Many homeowners apply this chemical to their trees to rid them of infestation by aphids or other insects. Malathion is classified as an organophosphate insecticide. Exposure to malathion is very dangerous to humans and animals because it acts as an irreversible inhibitor of acetylcholinesterase. Predict what might happen to synaptic communication between cholinergic neurons if an individual or animal was poisoned with malathion, and clearly describe the mechanisms at work.The tobacco industry takes full advantage of neurochemistry because nicotine is a highly addictive drug that increases dopamine release into the nucleus accumbens. What is the mechanisms by which this occurs? A. There are nicotinic acetylcholine receptors on dopaminergic neurons in the ventral tegmental area B. There are nicotinic acetylcholine receptors on presynaptic dopaminergic terminal buttons within the nucleus accumbens C. There are nicotinic acetylcholine receptors on opiate neurons in the ventral tegmental area D. nicotine stimulates dynorphin cells within the nucleus accumbens to increases dopamine releaseWhich type of drug would be an antidote to atropine poisoning?a. nicotinic agonistb. anticholinergicc. muscarinic agonistd. α-blocker
