ANSWERS
What does the study of disease processes aid in understanding?
Ans: Normal functions.
What do Phase IV clinical drug trials involve?
Ans: Testing a drug only on the specific human population who have the condition that the drug is
intended to treat.
What is the result of negative feedback?
Ans: A response that opposes the original deviation from normal.
Is blood clotting an example of positive feedback?
Ans: Yes, because the action of the effector enhances the stimulus.
What is the purpose of daily thyroid hormone replacement medication?
Ans: To maintain normal thyroid hormone levels.
What does stratified epithelial tissue provide?
,Ans: Protection, but it does not transport substances between the internal and external environments.
What is the function of sebaceous glands?
Ans: To lubricate the skin.
Can enamel be regenerated?
Ans: No, enamel cannot be regenerated.
How can motor nerve fibers in the skin regulate blood flow?
Ans: By affecting the diameter of cutaneous blood vessels.
Are blood plasma and interstitial fluid separated from each other?
Ans: Yes, but there is communication and exchange between these fluids.
What does physiology emphasize?
Ans: Cause-and-effect mechanisms.
What is the study of how disease or injury alters physiological processes called?
Ans: Pathophysiology.
What is the first step in the scientific method?
Ans: The formation of a hypothesis.
Which phase of clinical trials maximizes the number of test participants?
,Ans: Phase III clinical trials.
What do Phase I clinical trials NOT involve?
Ans: Testing on the target human population.
What is the term for measurements in an experiment where the subject's group status is unknown?
Ans: Blind measurement.
What makes a hypothesis scientific?
Ans: It can be tested.
What must a theory be based on to be considered scientific?
Ans: Reproducible data.
What is the normal range of blood glucose concentration after fasting?
Ans: Approximately 70 to 99 mg/100 ml.
What is the normal range of arterial blood pH?
Ans: 7.35-7.45.
In a feedback loop, what does the integrating center send information to?
Ans: The effector.
What are the regulators of effectors in most feedback loops?
Ans: Hormones and nerve impulses.
, What are homeostatic regulatory mechanisms that are 'built-in' to the organs?
Ans: Intrinsic mechanisms.
What type of homeostatic regulatory mechanisms are the endocrine and nervous systems considered?
Ans: Extrinsic mechanisms.
When blood glucose levels rise, what role do pancreatic islets serve in the feedback loop?
Ans: They act as the integrating center.
What detects a decrease in mean arterial pressure?
Ans: A sensor.
What type of feedback occurs when platelets accumulate at a damaged vessel site?
Ans: Positive feedback.
What is the role of platelets in the positive feedback mechanism during vessel damage?
Ans: They act as effectors.
What is pathophysiology?
Ans: The study of how disease processes affect the function of the body.
What is comparative physiology?
Ans: The study of the physiological differences and similarities among different species.
What is anatomy?
