1. Where is the gastrocnemius vein in relation to the femoral vein?

• A. Lateral
• B. Distal
• C. Superior
• D. Ventral

Correct answer: A

Rationale: The gastrocnemius vein is located lateral to the femoral vein. In anatomical terms, lateral refers to the direction towards the side of the body or away from the midline. In this case, the gastrocnemius vein is positioned to the side of the femoral vein. The term 'distal' refers to being further away from the point of reference, 'superior' indicates a higher position, and 'ventral' refers to the front or anterior aspect of the body. Therefore, the correct answer is A. Lateral.

2. What is the term for the shedding of the outermost layer of the epidermis?

• A. Desquamation
• B. Exfoliation
• C. Keratinization
• D. Epidermolysis

Correct answer: A

Rationale: Desquamation is the correct term for the shedding of the outermost layer of the epidermis. This process is essential for skin renewal, allowing the removal of dead skin cells from the skin's surface. Exfoliation, on the other hand, involves the removal of dead skin cells through mechanical or chemical methods. Keratinization refers to the process where skin cells produce the protein keratin, contributing to the skin's protective barrier. Epidermolysis is a condition characterized by the separation of the epidermis from the dermis due to a structural defect in the skin.

3. Which of the following is a genetic condition that affects the respiratory system?

• A. Asthma
• B. Cystic fibrosis
• C. Mycosis
• D. Surfactant Deficiency

Correct answer: B

Rationale: The correct answer is B, Cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It leads to the production of thick mucus in the lungs, causing breathing difficulties and increasing the risk of respiratory infections. Choice A, Asthma, is a chronic respiratory condition characterized by inflammation and narrowing of the airways, but it is not a genetic condition. Choice C, Mycosis, refers to fungal infections and is not a genetic condition specifically affecting the respiratory system. Choice D, Surfactant Deficiency, is a condition related to respiratory distress syndrome in newborns and is not a genetic disorder affecting the respiratory system in general.

4. What is the major difference between somatic and germline mutations?

• A. Somatic mutations usually benefit the individual while germline mutations usually harm them.
• B. Since germline mutations only affect one cell, they are less noticeable than the rapidly dividing somatic cells.
• C. Somatic mutations are not expressed for several generations, but germline mutations are expressed immediately.
• D. Germline mutations are usually inherited while somatic mutations will affect only the individual.

Correct answer: D

Rationale: The major difference between somatic and germline mutations is that germline mutations are usually inherited and can be passed on to offspring, while somatic mutations occur in non-reproductive cells and only affect the individual in which they occur. This means that germline mutations have the potential to be present in future generations, while somatic mutations do not.

5. Which of the following is NOT a function of the liver?

• A. nutrient processing
• B. blood filtration and detoxification
• C. cholesterol and lipoprotein production
• D. insulin production and blood sugar regulation

Correct answer: D

Rationale: The correct answer is D. The liver does not produce insulin; instead, insulin is produced by the pancreas. The liver plays a crucial role in regulating blood sugar levels by storing and releasing glucose but does not directly produce insulin. Choices A, B, and C are functions of the liver. Nutrient processing, blood filtration, detoxification, cholesterol, and lipoprotein production are essential roles performed by the liver to maintain overall metabolic balance and health.
