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 5 of 5
Which hormone stimulates milk production in the breasts during lactation?
Correct Answer: C
Rationale: Prolactin is the hormone responsible for stimulating milk production in the breasts during lactation. It is produced by the pituitary gland and plays a crucial role in the initiation and maintenance of lactation. While norepinephrine, antidiuretic hormone, and oxytocin have roles in various physiological processes, they do not directly stimulate milk production. Therefore, the correct answer is prolactin.
