HESI A2 Version 1 Anatomy and Physiology Questions
Question 1 of 5
Which of the following hormones are tropic hormones? (Select one that doesn't apply.)
Correct Answer: C
Rationale: Tropic hormones are hormones that stimulate the release of other hormones from target endocrine glands. Somatotropin (A) is growth hormone from the anterior pituitary that acts directly on tissues. Follicle-stimulating hormone (B) and Thyroid-stimulating hormone (D) are tropic hormones that act on the gonads and thyroid gland, respectively, to stimulate the production of other hormones. Antidiuretic hormone (C) is not a tropic hormone; it regulates water balance by acting on the kidneys to reduce water excretion.
Question 2 of 5
What is the name of the structure that prevents food from entering the airway?
Correct Answer: D
Rationale: The structure that prevents food from entering the airway is the epiglottis. The epiglottis is a flap of cartilage located behind the tongue at the top of the larynx. During swallowing, the epiglottis covers the opening of the trachea, directing food and liquids to the esophagus instead of entering the airway. This mechanism ensures that food safely passes into the digestive system, avoiding any blockage of the respiratory pathway.
