Answer to Question 1

A, B, C
Feedback:
Situated at the base of the forebrain, the hypothalamus receives input from virtually all other areas of the brain, including the limbic system, cerebral cortex and the special senses that are controlled by the cranial nerves: smell, sight, touch, taste, hearing. Because of its positioning, the hypothalamus is able to influence, and be influenced by, emotions and thoughts. The hypothalamus also is located in an area of the brain that is poorly protected by the bloodbrain barrier, so it is able to act as a sensor to various electrolytes, chemicals, and hormones that are in circulation and do not affect other areas of the brain. It does not float within the ventricles of the brain, and it is located to allow input from the limbic system.

Answer to Question 2

C
Feedback:
Convert 1 g to mg by multiplying 1 g times 1,000 mg. There are 500-mg in each tablet. Dividing the 1000 mg prescribed dosage by 500-mg available dosage, the answer is two tablets.
