1. What is the purpose of genetic counseling?

• A. To treat genetic disorders.
• B. To diagnose genetic diseases in newborns.
• C. To provide information and support to individuals and families with genetic risks.
• D. To collect DNA samples for research purposes.

Correct answer: C

Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.

2. What is the process by which damaged muscle tissue repairs and rebuilds itself?

• A. Degeneration
• B. Regeneration
• C. Hyperplasia
• D. Metaplasia

Correct answer: B

Rationale: Regeneration is the correct answer. It is the process by which damaged muscle tissue repairs and rebuilds itself. New muscle cells are formed during regeneration to replace the damaged ones, allowing the muscle to heal and regain its function. Degeneration refers to tissue breakdown, hyperplasia is the increase in the number of cells in an organ or tissue, and metaplasia is the transformation of one type of tissue into another.

3. Which organ serves as the human body's command center, integrating sensory information and coordinating movement and vital functions?

• A. Lungs
• B. Brain
• C. Kidneys
• D. Stomach

Correct answer: B

Rationale: The brain is the human body's command center, responsible for integrating sensory information, coordinating movement, and regulating vital functions such as breathing, heart rate, and digestion. While the lungs, kidneys, and stomach perform crucial functions in the body, they do not have the central role of serving as the command center for these essential bodily processes. The lungs are primarily involved in respiration, the kidneys in filtering blood and regulating fluid balance, and the stomach in digestion. However, none of these organs have the comprehensive control over sensory integration, movement coordination, and vital functions like the brain does.

4. Which of the following is not part of the digestive system?

• A. Esophagus
• B. Liver
• C. Stomach
• D. Pancreas

Correct answer: D

Rationale: The correct answer is 'D: Pancreas.' While the pancreas contributes to digestion by secreting enzymes, it is not part of the main digestive tract. The esophagus, liver, and stomach are integral components of the digestive system. The esophagus helps in the transport of food to the stomach, the stomach aids in food breakdown, the liver produces bile for fat digestion, and the pancreas secretes digestive enzymes. Therefore, the pancreas is the correct answer as it is not part of the primary digestive tract but supports digestion through enzyme secretion.

5. Which of the following pathologies is caused by a virus?

• A. Asthma
• B. Cystic Fibrosis
• C. Epiglottitis
• D. Influenza

Correct answer: D

Rationale: The correct answer is D, Influenza. Influenza is a viral infection caused by the influenza virus. Asthma and cystic fibrosis are not caused by viruses. Asthma is a chronic respiratory condition related to inflammation and airway constriction, while cystic fibrosis is a genetic disorder affecting the lungs and other organs. Epiglottitis is most commonly caused by bacteria, particularly Haemophilus influenzae type B, rather than a virus.
