Answer to Question 1

Ans: D
Feedback:
The mesolimbic pathway is thought to be involved in pleasurable sensations and euphoria resulting from substance abuse. Deficiencies in the nigrostriatal pathway result in movement disorders (eg, Parkinson's disease) and contribute to certain side effects of antipsychotic medications. The mesocortical pathway is thought to mediate both the negative and cognitive symptoms of psychosis. The tuberoinfundibular pathway regulates prolactin secretion.

Answer to Question 2

Ans: D
Feedback:
Neurotransmitters are referred to as first messengers, which refers to molecules that communicate information or change from one cell or cell group to another, cause an immediate effect, and are typically found in circuitry that produces behavior. Glial cells are not involved in neurotransmission and receptor cells do not lie within the synapse.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.
