Textbook Question
Chapter 5, Problem 3TAHL
The hormone insulin enhances the carrier-mediated transport of glucose into most of the body’s cells but not into brain cells. The uptake of glucose from the blood by neurons does not depend on insulin. Knowing the brain’s need for a continuous supply of blood-borne glucose, predict the effect that insulin excess would have on the brain.

- Serotonin, norepinephrine, and dopamine are a group of neurotransmitters collectively called monoamines. A lack of these monoamines has been linked to depression. Depression is treated with dru that prolong the effect of these neurotransmitters either by preventing the re-uptake of the neurotransmitters, or by inhibiting the enzyme that breaks down these neurotransmitters. Which of the following statements about neurotransmitters'are true? The table lists the classifications of three antidepressants. Antidepressant Classification fluoxetine selective serotonin re-uptake inhibitor (SSRI) phenelzine monoamine oxidase (MAO) inhibitor amitriptyline tricyclic antidepressant Check all that apply. View Available Hint(s) MAO inhibitors are examples of monoamine antagonists. EFluoxetine inhibits the enzyme that breaks down monoamines. ODopamine plays a role in feelings of pleasure and pain.

Which of the following symptoms would you predict: blurring of vision, excess tear formation, frequent or involuntary urination, pallor (pale skin), muscle twitching, orcramps? Would atropine be an effective drug to treat the symptoms?(See Clinical Impact 16.2 for the action of atropine.) Explain.arrow_forwardThe autonomous nervous system regulates involuntary functions of the body and can be subdivided into the sympathetic and the parasympathetic nervous system. Both of these systems control the same group of body functions, but have opposite effects on the functions they regulate. The sympathetic nervous system prepares the body for intense physical activity like the fight-or-flight response. The parasympathetic nervous system has the opposite effect and relaxes the body and inhibits or slows many high energy functions. Which of the following involuntary effects in the body are brought about by the sympathetic nervous system during a fight-or- flight situation? i. Increased salivation ii. Increased digestion ii. Loss of bowel and bladder control iv. Body shivering Сrying Pupil dilation B. i, iv and v V. vi. A. i, ii and vi C. iii, iv and vi D. iii and varrow_forward
- If a patient was experiencing difficulty controlling their movement and displaying motor tremors and this problem was seen ONLY in the central nervous system (not PNS), what system in the central nervous system is likely where the dysfunction is located, what neurotransmitter would likely be related to these symptoms, and what would be the effect of blocking reuptake for this neurotransmitter if the patient was given a reuptake inhibitor for this neurotransmitter?arrow_forwardThere is a toxin extracted from pufferfish called tetrodotoxin (TTX), which completely inhibits (blocks) voltage-gated sodium channels. In low doses it can cause a slight numbness (people eat contaminated pufferfish sometimes!), in high doses it is lethal. Why is this the case? It prevents glutamate uptake and reuptake, causing seizures in the brain Ob. It causes excess neuronal activity, leading to excitotoxicity and cell death It destroys myelin around axons, slowing action potential propagation It prevents action potentials from being initiated, stopping all synaptic transmission O 0 o oarrow_forwardDrugs called selective serotonin reuptake inhibitors (SSRIs) affect the reuptake of neurotransmitter by presynaptic cells. SSRIs are used for the treatment of depression. Serotonin normally causes an excitatory postsynaptic potential. Explain why neurotransmitter reuptake is important. And describe what effect the SSRI would have on the response of these postsynaptic cells and why.arrow_forward

Use figures and diagrams to illustrate your answer. (This is a neuroscience question)arrow_forwardNeuroactive drugs, such as the antidepressant fluoxetine, function by affecting the metabolism of the brain. After the neurotransmitter serotonin has crossed the syrupse and attached to the post- synaptic neuron, the serotonin is normally reabsorbed by the pre-synaptic neuron. Fluoxetine inhibits the reuptake of serotonin. allowing it to remain in the synapse much longer than normal A Synapse O a. Z O b. Y с. Х d. W W- Fluoxetine inhibits the process above labelled...

- Glutamate is the major excitatory neurotransmitter in the brain. Because too much glutamate can cause excess Ca+2/Na+2 influx and excitatory in post-synaptic cells, the balance between excitation and inhibition must be tightly regulated. Calling upon only mechanisms that are directly part of the glutamate life cycle, describe two ways that you could experimentally limit or prevent glutamate excitotoxicity.arrow_forwardHeroin (diamorphine) is: O an opioid receptor antagonist. O a long-acting opioid agonist that produces dysphoria. O a drug that is metabolised in humans to morphine. a drug with high liability for physical dependence and low liability for psychological dependence.

O inhibiting alpha 1-adrenoceptors. O inhibiting the breakdown of noradrenaline by monoamine oxidase.arrow_forwardIn some cases of ADD (attention deficit disorder) the impulsive, erratic behavior can be normalized with drugs that stimulate the central nervous system.
