1. Are the ears lateral to the eyes?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. Lateral means towards the side or away from the midline. In human anatomy, the ears are located on the sides of the head, which is indeed lateral to the eyes that are positioned more towards the front of the face. Therefore, the statement that the ears are lateral to the eyes is true. Choice B is incorrect because the ears are not positioned closer to the midline than the eyes. Choice C is incorrect as the relationship between the ears and eyes in terms of lateral positioning can be determined anatomically. Choice D is incorrect as there is a clear anatomical relationship between the ears and eyes.

2. Does the diaphragm separate the thoracic and abdominopelvic cavities?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. The diaphragm is a dome-shaped muscle that separates the thoracic cavity, which contains the heart and lungs, from the abdominopelvic cavity, which contains organs such as the stomach, liver, and intestines. It plays a crucial role in breathing by contracting and relaxing to help with the process of respiration. Therefore, the statement is accurate. Choice B is incorrect because the diaphragm indeed separates these two cavities. Choice C is incorrect as the information provided allows one to determine the correct answer. Choice D is incorrect as the correct answer is 'True.'

3. Which of the following must the human body obtain from the environment in order to survive?

• A. Nitrogen
• B. Waste products
• C. Water
• D. Carbon dioxide

Correct answer: C: Water

Rationale: The correct answer is C: Water. Water is essential for the human body to survive as it plays a crucial role in various physiological processes like digestion, circulation, and temperature regulation. Nitrogen is abundant in the atmosphere and is not directly obtained from the environment for survival. Waste products are materials that need to be eliminated from the body, not obtained for sustenance. Carbon dioxide is a byproduct of cellular respiration and is expelled from the body through breathing, not obtained as a nutrient.

4. What is the membrane on the surface of a lung called?

• A. visceral pleura
• B. parietal pleura
• C. visceral pericardium
• D. parietal pericardium

Correct answer: A: visceral pleura

Rationale: The correct answer is A: visceral pleura. The membrane covering the surface of the lungs is called the visceral pleura. It is a serous membrane that is in direct contact with the lung tissue. Choices B, C, and D are incorrect because the parietal pleura covers the inner surface of the chest wall and diaphragm, the visceral pericardium covers the surface of the heart, and the parietal pericardium is the outer layer of the pericardium surrounding the heart, respectively.

5. What causes wrinkled and sagging skin?

• A. Drinking too much water
• B. Heredity alone
• C. Loss of subcutaneous fat and reduced levels of elastin and collagen
• D. Excess subcutaneous fat

Correct answer: Loss of subcutaneous fat and reduced levels of elastin and collagen

Rationale: Wrinkled and sagging skin is primarily caused by the loss of subcutaneous fat and reduced levels of elastin and collagen in the skin. Choice A is incorrect as drinking too much water does not lead to wrinkled and sagging skin. Choice B is incorrect because heredity alone does not cause this condition. Excess subcutaneous fat, as mentioned in Choice D, can contribute to a different skin appearance, such as puffiness, but not wrinkled and sagging skin.
