Question 1 of 5
Which structure is located on the sternum?
Correct Answer: A
Rationale: The xiphoid process is the structure located at the bottom of the sternum. It is a small cartilaginous process that ossifies with age. The sesamoid bone is a small bone embedded within a tendon, not typically found on the sternum. The hyoid bone is a U-shaped bone located in the neck, not on the sternum. 'Ossified' refers to a structure that has become hardened like bone, but it is not a specific structure located on the sternum.

Question 4 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.
