Answer to Question 1

ANS: D
Substance P is a neurotransmitter in pain transmission pathways. Blocking the release of sub-stance P by morphine reduces pain. The opiates morphine and heroin bind to endorphin and enkephalin receptors on presynaptic neurons. Dopamine is a neurotransmitter involved in activity. Acetylcholine plays a role in nerve conduction presynaptically.

Answer to Question 2

ANS: B
The reticular activating system is responsible for wakefulness, not the corpora quadrigemina, the cerebellum, or the hypothalamus.
