- Thermoreceptors in the hypothalamus sense the temperature of the blood. When blood temperature begins to decrease, the hypothalamus releases TRH, which stimulates the release of TSH from the anterior pituitary gland. TSH stimulates the thyroid gland to release thyroid hormone (TH). TH stimulates an increase in body temperature, which causes the hypothalamus to decrease the release of TRH. In this reflex pathway, what is the response? A) Increased body temperature B) Increased release of TH C) Thermoreceptors D) Decreased release of TRHA patient has been exposed to the organophosphate pesticide malathion,which inactivates acetylcholinesterase. 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.The most important reward circuit in the brain is the mesolimbic pathway. Dopaminergic neurons originate in the _____ and connect to the _____ and other structures. A) hippocampus; amygdala B) amygdala; prefrontal cortex C) ventral tegmental area (VTA); nucleus accumbens D) nucleus accumbens; prefrontal cortex
- Russell is 72 years old and is still working part-time as a professor. He has noticed some arm and hand shaking in the past year, but assumed it must be related to low or high blood sugar levels because he has had some issues with that in the past. However, the shaking/twitching has become more consistent lately and does not seem to be correlated with his diet. Russell’s doctor said that the stress of his job could be the problem, so he took the entire summer off from teaching.When he returned to work in the fall, Russell and his students noticed that his handwriting has become nearly illegible. Drinking a cup of coffee without spilling had also become a challenge. Russell returned to his doctor, who performed a physical exam and a few tests. Here are the notable results: shuffling gait, mild bradykinesia, mild voice tremor, intermittent rigidity of the limbs, and normal EEG.Which of Russell’s physical exam findings could be related to a brain condition?Russell is 72 years old and is still working part-time as a professor.
