Which of the following is true about the corticonuclear tract:

Correct Answer: C

Rationale: Controls voluntary movements of the musclof the face, head, and neck . The corticonuclear tract originatfrom the motor cortex, specifically the precentral gyrus (not cerebellum, making A incorrect), and descends through the internal capsule to terminate in brainstem cranial nerve nuclei (not spinal cord, making D wrong). It donot decussate completely in the midbrain (B is false); instead, its fibers partially cross at various brainstem levels, with some (e.g., cranial nerve 7 lower face) contralateral and others (e.g., 11) bilateral. Choice C is true; it controls voluntary movements of musclin the face (e.g., smiling via cranial nerve 7), head (e.g., tongue via 12), and neck (e.g., sternocleidomastoid via 11), via nuclei of cranial nerv5, 7, 9, 10, 11, and 12. For example, a cortical lesion causcontralateral lower facial weakness, demonstrating its role in voluntary control. Thus, C accurately describthe corticonuclear tracts function, making it the correct answer.

Correct Answer: C

Rationale: Blood sugar level affects appetite and food intake . Blood glucose influenchunger via hypothalamic signaling low levels stimulate appetite (e.g., ghrelin release), while high levels signal satiety (e.g., insulin response). Choice A is false; cold temperaturincrease intake for thermogenesis, per physiological studies. Choice B is wrong; insulin injections increase hunger by lowering blood sugar, not decreasing intake immediately. Choice D is incorrect; multiple systems (e.g., hypothalamus, gut hormonlike CCK) regulate intake, not one. is false; the lateral hypothalamus drivhunger, while the ventromedial hypothalamus is the satiety center, per lesion studi(e.g., Anand & Brobeck, 1951). Cs truth is evident in diabetes, where glucose dysregulation alters eating patterns, making it the correct answer over oversimplified or reversed claims.

Correct Answer: A

Rationale: The dreams of starved individuals are not affected by their state , which is false. Starvation alters dreams studilike the Minnesota Starvation Experiment (1944) showed food-obsessed dreams in starved subjects. Choice B is true; the lateral hypothalamus drivhunger, per lesion studies. Choice C is correct; insulin lowers blood sugar, increasing appetite. Choice D is accurate; direct stomach injection suppressappetite via stretch receptor feedback. is true; stomach distention signals the VMH (satiety center) to reduce hunger. As falsehood is evident in psychological data hunger permeatcognition, including dreams contrasting with the physiological truths of B-E, making it the correct answer.

Correct Answer: B

Rationale: Doctors overestimate the amount of information they give to patients . Research (e.g., patient recall studies) shows doctors assume theyve conveyed more details than patients grasp, impacting care. Choice A is false; many doctors focus on biomedical data, missing emotional cues, per communication studies. Choice C is incorrect; trust in the relationship boosts drug adherence and outcom(e.g., placebo effects). Choice D is wrong; patients value empathy alongside skill, per satisfaction surveys. is false; being called casoften alienatpatients, reducing rapport. Bs truth reflects a common bias doctors overestimate clarity without feedback evident in miscommunication cases, making it the correct answer.

Correct Answer: D

Rationale: Employment record , per the document, though context is unclear. Employment record reflects behavioral consistency (e.g., responsibility), a key personality indicator in occupational psychology. Choice A (family life) influencpersonality but is less direct family shaptraits, not assessthem. Choice B (relationships) reveals traits (e.g., agreeableness) but is subjective and variable. Choice C (professional affiliations) shows interests, not core traits. Ds prominence likely tito observable, longitudinal data (e.g., job performance reflecting conscientiousness), unlike the formative (A, B) or associative factors. Without slides, D aligns with practical assessment norms, making it the correct answer.
