A woman consults her physician about a study (Women's Health Initiative) discussing an increased risk for breast cancer if taking hormones. The physician can allay her fears by sharing which of the following findings?
 
  A)
  Only women with a family history of breast cancer had an increased risk for developing breast cancer while on birth control pills.
  B)
  This 26 increased risk for developing invasive breast cancer occurred in women taking combined continuous estrogen-progesterone therapy.
  C)
  The increased risk for developing inflammatory breast cancer occurred in women taking hormone replacement therapy when they were over the age of 45.
  D)
  Follow-up studies demonstrated that there was only a 3 increase in risk for developing breast cancer if hormones were discontinued immediately.

Question 2

Which of the following statements best captures an aspect of the neural control of sexual function?
 
  A)
  The sensory system contained in the testes communicates with the spinal cord by way of afferent pathways.
  B)
  Perineal stimulation transmits signals to the thalamus and hypothalamus.
  C)
  The spinal cord plays a central role, with the limbic system and cerebral cortex also contributing.
  D)
  Sympathetic stimulation causes the shunting of blood resulting in erection, while parasympathetic stimulation results in detumescence.

Answer to Question 1

Ans:
B

Feedback:

The WHI added to the breast cancer concern by reporting a 26 increased risk of invasive breast cancer in the women using CCEPT. Results from a 3-year WHI follow-up study revealed that the breast cancer risk of women who stopped taking CCEPT continued at a rate similar to that observed during the intervention.

Answer to Question 2

Ans:
C

Feedback:

Afferent impulses from sensory receptors in the glans penis pass through the pudendal nerve to ascending fibers in the spinal cord by way of the sacral plexus, while stimulation of other perineal areas can transmit signals to higher brain centers, such as the limbic system and cerebral cortex. The thalamus and hypothalamus do not play a central role in the neural control of male sexual function, and arousal can result from parasympathetic stimulation.
