- The hormone insulin enhances the carrier-mediated transport of glucose into most of the bodys cells but not into brain cells. The uptake of glucose from the blood by neurons does not depend on insulin. Knowing the brains need for a continuous supply of blood-borne glucose, predict the effect that insulin excess would have on the brain.arrow_forwardBenzodiazepines bind to GABAa receptors and increase the effects of GABA. Which effect would you predict to see after treatment with benzodiazepines? Increased influx of potassium flow. Increased G protein action. Increased influx of chloride. Increased influx of GABA.arrow_forwardWhich of the following is stimulated by the Sympathetic nervous system? Question 9 options: Increased dilation of respiratory tubes in lungs during exercise Increased contractions of the digestive system for peristalsis Increased contractions of rectum muscles to defecate Increased saliva and tear production Increased contractions of urinary bladder to urinatearrow_forward
- All the following regarding sympathetic nervous system are true except: * It is involved in stress & emergency conditions. It has a vasodilatory effect on skeletal muscle blood vessels during rest. All its preganglionic fibres are cholinergic. Its stimulation increases the cardiac properties. E O Its stimulation causes urine retention.arrow_forwardWhich of the following functions is NOT a unique role of the sympathetic nervous system? Constriction or dilation of blood vessels Decrease blood glucose levels Release of renin from the kidneys to increase blood pressure Activation of sweat glands Innervation of adrenal medullaarrow_forwardBreaks down lipid Increased sympathetic tone Decreased sympathetic tone Increased parasympathetic tone Decreased parasympahtetic tonearrow_forward
- The 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.

- 1) As a physiologist, which of the following terms should you immediately associate with negative feedback regulation? Answer choices Constancy Relative constancy Relative constancy in interstitial fluid Relative constancy in intracellular fluid 2) Which of the following is true about physiological set-points? Answer choices They act as the integrating center in a negative feedback arc They represent the internal environment They are determined by the actions of the receptors and integrating centers They are constant They act as the effector in a negative feedback arc 3) What is the general purpose of negative feedback mechanisms? Answer choice a. to maintain a constant internal environment b. To anticipate changes in the environment c. To return a variable to its set-point d. To bring about the rapid change of a variable e. To detect changes in the external environmentarrow_forwardWhich of the following best describes the sympathetic nervous system? i) Associated with stressful situations ii) Norepinephrine may be involved iii) Associated with voluntary responses i only O ii only Oi and ii only i and iii only O i, ii, and iiiarrow_forwardWhich of the following is comparable to a negative feedback cycle? opening of voltage-gated Na" channels in response to a depolarizing graded potential movement of K* through leak channels opening of voltage-gated K* channels in response to a depolarizing graded potential operation of the Na -K ATPase at rest opening of voltage-gated Ca- channels in response to an action potential arriving at the axon terminalarrow_forward
