1. Which lobe of the brain is primarily responsible for processing sensory information related to touch, temperature, and body position?

• A. Frontal lobe
• B. Parietal lobe
• C. Occipital lobe
• D. Temporal lobe

Correct answer: B

Rationale: The parietal lobe is primarily responsible for processing sensory information related to touch, temperature, and body position. It plays a crucial role in interpreting sensations from different parts of the body, including proprioception, which is the awareness of body position. The frontal lobe is more associated with functions like decision-making and personality, the occipital lobe is primarily involved in visual processing, and the temporal lobe is responsible for auditory processing and memory. Therefore, the parietal lobe is the correct answer for this question.

2. Which connective tissue type attaches muscles to bones?

• A. Ligaments
• B. Tendons
• C. Cartilage
• D. Fascia

Correct answer: B

Rationale: Tendons are the correct answer. They are strong connective tissues that connect muscles to bones, allowing movement when muscles contract. Ligaments connect bones to other bones, providing joint stability. Cartilage is a firm, flexible connective tissue present in joints and the outer ear. Fascia is a connective tissue that surrounds muscles, blood vessels, and nerves, offering support and protection. Therefore, the correct tissue type that connects muscles to bones is tendons.

3. How might the headrest on a car prevent traumatic injury?

• A. By limiting hyperflexion of the neck
• B. By limiting hyperextension of the neck
• C. By reducing vertebral compression
• D. By preventing disc degeneration

Correct answer: B

Rationale: The headrest on a car is designed to prevent traumatic injury by limiting hyperextension of the neck during a rear-end collision. This helps reduce the risk of whiplash and other neck injuries that may occur when the head is forcefully thrown backward. Choice A is incorrect because hyperflexion is not the primary concern in rear-end collisions. Choice C is incorrect as the headrest does not directly reduce vertebral compression. Choice D is incorrect because the headrest is not directly involved in preventing disc degeneration.

4. Which feature of the ear is most medial?

• A. Pinna
• B. Tympanic membrane
• C. Cochlea
• D. Outer canal

Correct answer: B

Rationale: The tympanic membrane, also known as the eardrum, is the most medial feature in the ear. It separates the outer ear from the middle ear and serves as a barrier that vibrates in response to sound waves, transmitting vibrations to the middle ear ossicles. The pinna, cochlea, and outer canal are located more laterally in the ear anatomy. The pinna is the visible part of the ear located on the lateral side of the head, the cochlea is a spiral-shaped structure in the inner ear responsible for hearing, and the outer canal refers to the external auditory canal leading to the eardrum.

5. What is the primary function of the respiratory system?

• A. To absorb oxygen
• B. To transport nutrients
• C. To produce sound and speech
• D. To regulate blood pressure

Correct answer: A

Rationale: The primary function of the respiratory system is to absorb oxygen from the air into the bloodstream and expel carbon dioxide from the body. This process is essential for cellular respiration and the production of energy in the body. Option A, 'To absorb oxygen,' aligns with this crucial function, making it the correct choice. Choices B, C, and D are incorrect as they do not represent the primary function of the respiratory system. The respiratory system is not responsible for transporting nutrients (choice B), producing sound and speech (choice C), or regulating blood pressure (choice D).
