Which of the following is true about vomiting center:

Correct Answer: D

Rationale: Located in the medulla oblongata . The vomiting center is in the medulla oblongata, near the area postrema (not hypothalamus, making A wrong, which regulatnausea indirectly). Vomiting is an involuntary reflex (B is false), unlike swallowing, triggered by medullary integration of signals. It receivinput from gastric stretch receptors via the vagus nerve (cranial nerve 10) (C is wrong), responding to distension (e.g., overeating). D is true; the medulla coordinatvomiting via cranial nerv9 (sensation), 10 (motility), and 8 (vestibular), with the chemoreceptor zone detecting emetics. Lesions here abolish vomiting, as in brainstem stroke, unlike hypothalamic effects. Thus, D is the true statement.

Correct Answer: B

Rationale: Doctors overestimate the amount of information they give to patients . Studies, such as those in medical communication research, show doctors often assume theyve explained more than patients recall, overestimating information delivery. Choice A is false; while some doctors notice emotional clues, many prioritize biomedical aspects, missing cu(e.g., patient anxiety). Choice C is incorrect; a strong patient-doctor relationship enhanctrust, improving drug adherence and placebo effects, thus affecting outcomes. Choice D is wrong; patients value technical skill but also seek empathy and communication, per patient satisfaction surveys. is false; being called casdepersonalizpatients, often reducing trust, as humanistic care models emphasize. This overestimation stems from cognitive bias doctors assume clarity without verifying patient understanding impacting care quality. Real-world examplinclude miscommunication leading to non-compliance, underscoring Bs truth.

Correct Answer: D

Rationale: Time of the day . While circadian rhythms influence eating patterns, immediate food intake is less driven by clock time than physiological cues. Choice A (blood sugar) directly regulathunger via hypothalamic glucoreceptors low levels trigger eating. Choice B (body temperature) affects intake; cold increasappetite for energy, per thermoregulation studies. Choice C (stomach fullness) suppresshunger through stretch receptor signals to the brainstem. (sight of food) potently stimulatappetite via reward pathways (e.g., dopamine in the nucleus accumbens). Time of day is secondary; it sets habits but lacks the direct, acute impact of glucose, fullness, or visual cues, as seen in free-feeding experiments. Thus, D plays the least role, making it the correct answer.

Correct Answer: A

Rationale: People in a society have one cultural expectation in all members , which is false. Societiare diverse, with varied cultural expectations across subgroups, not a singular norm. Choice B is true; societienable collective action (e.g., infrastructure) beyond individual capacity. Choice C is correct; ethnic diversity is common, as in multicultural nations. Choice D is accurate; shared territory and governance define societies, per sociological theory (e.g., Parsons). is true; subcultur(e.g., youth, religious groups) coexist within societies. As falsehood ignordiversity e.g., urban vs. rural expectations differ contrasting with the cooperative, pluralistic truths of B-E, making it the exception and correct answer.

Correct Answer: B

Rationale: Benefits of social relationships are equally distributed in the society , which is false. Social benefits vary e.g., socioeconomic status affects access to supportive networks, per epidemiology. Choice A is true; low social tiincrease mortality risk (e.g., loneliness studies). Choice C is correct; relationships aid disease prevention (e.g., support lowers stress). Choice D is accurate; social bonds influence lifelong health, per longitudinal data. is true; relationships impact physiology (e.g., oxytocin reduccortisol). Bs falsehood unequal distribution due to inequality contrasts with the well-supported health benefits of A, C, D, E, making it the exception and correct answer.
