1. Which cellular organelle is responsible for the production of
ATP through cellular respiration?
• A. Ribosome
• B. Mitochondrion
• C. Golgi apparatus
• D. Lysosome
• Answer: B
• Rationale: Mitochondria are known as the powerhouses of
the cell because they generate most of the cell's supply of
adenosine triphosphate (ATP) used as a source of chemical
energy.
2. Which plane divides the body into right and left halves?
• A. Frontal plane
• B. Transverse plane
• C. Sagittal plane
• D. Coronal plane
• Answer: C
, • Rationale: The sagittal plane divides the body into right
and left portions. A midsagittal plane divides it into equal
right and left halves.
3. What is the primary function of ribosomes within the cell?
• A. Lipid synthesis
• B. Protein synthesis
• C. Cellular detoxification
• D. ATP generation
• Answer: B
• Rationale: Ribosomes are composed of RNA and proteins,
and they serve as the site of protein synthesis by
translating messenger RNA (mRNA).
4. Which type of tissue covers body surfaces, lines cavities,
and forms glands?
• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue
• Answer: A
, • Rationale: Epithelial tissue covers the body surface, lines
internal cavities and hollow organs, and constitutes the
major tissue of glands.
5. Which directional term describes a position closer to the
point of attachment or trunk of the body?
• A. Distal
• B. Proximal
• C. Lateral
• D. Inferior
• Answer: B
• Rationale: Proximal means closer to the point of
attachment or origin (e.g., the elbow is proximal to the
wrist), whereas distal means farther away.
Integumentary System (Questions 6–10)
6. Which layer of the skin contains blood vessels, nerve
endings, hair follicles, and sweat glands?
• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Stratum corneum
• Answer: B
