1. The term "goiter" refers to a condition characterized by:

• A. Overproduction of cortisol from the adrenal glands
• B. Excessive growth of the thyroid gland
• C. Underproduction of parathyroid hormone (PTH)
• D. Deficiency of growth hormone from the pituitary gland

Correct answer: B

Rationale: The term 'goiter' specifically refers to the abnormal enlargement of the thyroid gland. This can be due to various reasons such as iodine deficiency, Hashimoto's thyroiditis, or Graves' disease. Options A, C, and D are incorrect as they describe conditions related to other glands and hormones in the endocrine system. It is important to differentiate between different endocrine disorders to accurately diagnose and treat patients. Therefore, the correct answer is B, as a goiter is characterized by the excessive growth of the thyroid gland.

• A. Creates a sense of mystery.
• B. Emphasizes the large size of the house.
• C. Suggests the house is in poor condition.
• D. Implies the house is haunted.

Correct answer: C

3. Identify the adverb in the following sentence: The patient waited anxiously for the doctor's news.

• A. waited

4. A study finds a specific gene linked to increased risk of heart disease. Does this mean everyone with that gene will develop heart disease?

• A. Yes, the gene deterministically causes heart disease.
• B. No, other factors also influence heart disease risk.
• C. We need more research to clarify the gene's exact role.
• D. Only people with a family history of heart disease need to worry.

Correct answer: B

Rationale: The presence of a specific gene linked to an increased risk of heart disease does not guarantee that everyone with that gene will develop the condition. Other factors such as lifestyle, environment, and overall health also play a significant role in determining an individual's risk of heart disease. Therefore, it is essential to consider these additional factors rather than solely attributing the risk to the gene itself.

5. Which part of the male urinary system is responsible for producing seminal fluid?

• A. Bladder
• B. Urethra
• C. Prostate gland
• D. Kidney

Correct answer: C

Rationale: The correct answer is C: Prostate gland. The prostate gland is responsible for producing seminal fluid, which is a milky fluid that nourishes and protects sperm. The bladder stores urine, the urethra is a tube that carries urine from the bladder out of the body, and the kidney filters waste products from the blood to produce urine. The prostate gland, located beneath the bladder, plays a crucial role in male reproductive health by contributing to semen production. Understanding the functions of each part of the male urinary system is important for comprehending reproductive anatomy and physiology.

6. During normal breathing, which muscle is the primary driver of inhalation by contracting and flattening to increase the volume of the thoracic cavity?

• A. Diaphragm
• B. Intercostal muscles
• C. Abdominal muscles
• D. Pectoral muscles

Correct answer: A

Rationale: The diaphragm is the primary muscle responsible for inhalation during normal breathing. When the diaphragm contracts and flattens, it increases the volume of the thoracic cavity, creating a negative pressure that allows air to rush into the lungs. The intercostal muscles also play a role in expanding the ribcage to assist with inhalation. However, the diaphragm is the main driver of the breathing process by creating the necessary space for the lungs to expand and fill with air.
