Semen leaves the male body when the penis is erect and
- A. urination occurs
- B. evacuation occurs
- C. excitement occurs
- D. ejaculation occurs
Correct Answer: D
Rationale: The correct answer is D: ejaculation occurs. When the penis is erect, semen is released from the male body through ejaculation. During sexual arousal, the muscles contract, pushing semen through the urethra and out of the body. Urination (choice A) is a separate process controlled by the bladder, not related to semen release. Evacuation (choice B) refers to bowel movements, not semen release. Excitement (choice C) is a psychological state and does not directly lead to semen leaving the body. Therefore, the correct answer is D as it accurately describes the physiological process of semen leaving the male body during ejaculation.
In order for milk to flow from the nipple of the mother into the mouth of the nursing infant, which of the following must occur?
- A. Myoepithelial cells must relax
- B. Prolactin levels must fall
- C. Oxytocin secretion from the posterior pituitary must take place
- D. The baby’s mouth must develop a strong negative pressure over the nipple
Correct Answer: C
Rationale: The correct answer is C because oxytocin is responsible for stimulating the contraction of myoepithelial cells around the alveoli in the mammary glands, causing milk ejection. This process is known as the let-down reflex. In contrast, choice A (myoepithelial cells must relax) is incorrect because they need to contract to push milk out. Choice B (prolactin levels must fall) is incorrect because prolactin is responsible for milk production, not milk ejection. Choice D (the baby's mouth must develop a strong negative pressure over the nipple) is incorrect because it is the mother's hormone release, not the baby's action, that causes milk flow.
