1. Smooth muscle is the only ____________ muscle in the body.

• A. Voluntary, striated
• B. Involuntary, non-striated
• C. Involuntary, striated
• D. Voluntary, non-striated

Correct answer: B

Rationale: Smooth muscle is the only involuntary, non-striated muscle type in the body. It is found in organs like the intestines and blood vessels, where it controls movements without conscious effort. Choice A is incorrect because voluntary muscles are under conscious control, while smooth muscle is involuntary. Choice C is incorrect because striations are not present in smooth muscle, unlike skeletal muscle. Choice D is incorrect because smooth muscle is not voluntary and lacks striations, making it different from skeletal muscle.

2. Which of the following choices contains an error in verb tense?

• A. She said that she would finish the report yesterday.
• B. We went to the store last week.
• C. They had seen the movie before it was released.
• D. The dogs will play outside when we arrive.

Correct answer: A

Rationale: The correct answer is choice A, 'She said that she would finish the report yesterday.' This sentence contains a verb tense error. The reported speech 'She said' requires the verb 'would' to maintain the past tense. Choices B and D are correct as they use the appropriate verb tenses 'went' and 'will play.' Choice C is also correct as it uses 'was released' to match the past perfect tense 'had seen.'

3. Based on the word parts, which of the following is a synonym for superlative?

• A. Relevant
• B. Surprising
• C. Excellent
• D. Unimportant

Correct answer: C

Rationale: The word 'superlative' implies the highest quality, which aligns with the meaning of 'excellent'. Therefore, 'excellent' is the correct synonym. Choice A, 'Relevant', does not convey the same meaning and is unrelated to superlative. Choice B, 'Surprising', suggests something unexpected rather than the highest quality. Choice D, 'Unimportant', is the opposite of what superlative represents, making it an incorrect choice.

4. A patient's body is not properly filtering blood. Which of the following body parts is most likely malfunctioning?

• A. Medulla
• B. Heart
• C. Nephrons
• D. Renal cortex

Correct answer: C

Rationale: Nephrons are the functional units of the kidneys responsible for filtering blood and removing waste products to form urine. If a patient's body is not properly filtering blood, it is most likely due to dysfunction or impairment in the nephrons of the kidneys. The heart is responsible for pumping blood, not filtering it, making choice B incorrect. The medulla and renal cortex are specific parts of the kidney but do not directly perform the filtration function carried out by the nephrons, making choices A and D incorrect.

5. What is the name of the sheath of connective tissue that surrounds a skeletal muscle?

• A. Epimysium
• B. Perimysium
• C. Endomysium
• D. Myofibril

Correct answer: A

Rationale: The correct answer is Epimysium. The epimysium is the outermost layer of connective tissue that surrounds a skeletal muscle, providing protection and support to the muscle as a whole. Perimysium, which surrounds bundles of muscle fibers known as fascicles, is not the sheath that surrounds the entire muscle. Endomysium surrounds individual muscle fibers, not the entire muscle. Myofibril is a structure within muscle fibers that contains the contractile proteins responsible for muscle contraction, but it is not the sheath of connective tissue surrounding the muscle.
