1. Which of the following best describes a plane that divides the body into upper and lower portions?

• A. Coronal
• B. Transverse
• C. Oblique
• D. Median

Correct answer: B

Rationale: The correct answer is B: Transverse. A transverse plane, also known as a horizontal plane, divides the body into upper and lower portions. This plane is perpendicular to the long axis of the body. Coronal planes divide the body into anterior and posterior portions. Oblique planes pass through the body at an angle, neither strictly horizontal nor vertical. The median plane passes longitudinally through the body, dividing it into equal left and right halves.

2. Beta waves, associated with alertness and focused attention, typically fall within the range of:

• A. 0.5-4 Hz
• B. 4-8 Hz
• C. 8-13 Hz
• D. 13-30 Hz

Correct answer: D

Rationale: Beta waves, associated with alertness and focused attention, typically fall within the range of 13-30 Hz. These waves are present when individuals are engaged in cognitive tasks, problem-solving, or focused mental activities. Options A, B, and C are incorrect because these frequency ranges are not characteristic of beta waves. Beta waves are higher in frequency and are associated with more active mental states compared to the ranges mentioned in options A, B, and C. Therefore, the correct answer is 13-30 Hz (Choice D).

3. Which of the following is an example of a correctly punctuated sentence?

• A. Beatrice is very intelligent; however, she just does not apply herself well enough in her classes to make good grades.
• B. Beatrice is very intelligent: she just does not apply herself well enough in her classes to make good grades.
• C. Beatrice is very intelligent; she just does not apply herself well enough in her classes to make good grades.
• D. Beatrice is very intelligent; she just does not apply herself well enough in her classes to make good grades.

Correct answer: D

Rationale: Option D is the correct answer as it uses a semicolon to correctly separate two independent clauses. In this sentence, 'Beatrice is very intelligent' and 'she just does not apply herself well enough in her classes to make good grades' are two independent clauses that are related but can stand alone as separate sentences. The semicolon is the appropriate punctuation mark to link these two closely related ideas. Choices A, B, and C are incorrect because they either use a comma splice (A), a colon (B), or lack appropriate punctuation (C) to separate the independent clauses.

4. On a highway map, the scale indicates that 1 inch represents 45 miles. If the distance on the map is 3.2 inches, how far is the actual distance in miles?

• A. 144 miles
• B. 160 miles
• C. 180 miles
• D. 200 miles

Correct answer: A

Rationale: To find the actual distance in miles, you need to set up a proportion using the scale provided (1 inch = 45 miles). Since the distance on the map is 3.2 inches, you can set up the proportion: 1 inch / 45 miles = 3.2 inches / x miles. Cross-multiply to solve for x: 1 * x = 45 * 3.2, x = 144. Therefore, the actual distance in miles is 144. Choices B, C, and D are incorrect because they do not accurately calculate the actual distance using the scale provided.

5. What is the scientific term for a muscle that helps another muscle perform its action?

• A. Agonist
• B. Antagonist
• C. Synergist
• D. Fixator

Correct answer: C

Rationale: A synergist is a muscle that assists the agonist, the primary muscle responsible for a specific movement, in performing that movement. Synergists stabilize joints and provide additional support to the prime mover muscle, enhancing the efficiency and effectiveness of the movement. Choice A, Agonist, refers to the muscle primarily responsible for a specific movement. Choice B, Antagonist, refers to a muscle that opposes the action of the agonist. Choice D, Fixator, refers to a muscle that stabilizes the origin of the prime mover muscle, maintaining the desired position during movement.
