1. Is the parietal pleura a visceral membrane?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: The statement that the parietal pleura is a visceral membrane is false. The parietal pleura is actually a membrane that lines the thoracic cavity and is responsible for protecting and cushioning the lungs. Visceral pleura, on the other hand, is the membrane that covers the surface of the lungs. Therefore, the parietal pleura is not a visceral membrane, making the correct answer 'False.' Choices C and D are not relevant as the question is asking for a true/false statement.

2. When does cell death first occur?

• A. At age 60.
• B. At age 50.
• C. At puberty.
• D. In the fetus.

Correct answer: D

Rationale: Cell death, also known as apoptosis, first occurs during fetal development when specific cells are programmed to die. This process is essential for shaping and organizing tissues and organs. Choices A, B, and C are incorrect because cell death begins much earlier, during fetal development, rather than later in life or at puberty. Understanding the timing of cell death in different stages of life is crucial in developmental biology.

3. Which of the following is a role of platelets in hemostasis?

• A. formation of plugs
• B. promotion of vasodilation
• C. conversion of prothrombin to thrombin
• D. activation of calcium

Correct answer: A

Rationale: Platelets play a crucial role in hemostasis by forming plugs to stop bleeding. Choice B is incorrect because platelets do not promote vasodilation; instead, they help in vasoconstriction. Choice C is incorrect as the conversion of prothrombin to thrombin is a function of the coagulation cascade involving various clotting factors, not platelets. Choice D is incorrect as platelets do not directly activate calcium; instead, they play a role in the activation of other clotting factors.

4. When the body is placed in the anatomical position, which of the following is not true?

• A. The head is facing to the front.
• B. The palms are facing forward.
• C. The body is erect.
• D. The upper limbs are at the sides.

Correct answer: B

Rationale: In the anatomical position, the palms are facing forward, not backward. Choice A is correct because the head is indeed facing to the front. Choice C is correct as the body is erect. Choice D is correct as the upper limbs are positioned at the sides. Therefore, the incorrect statement is that the palms are facing forward.

5. Blood cells are produced in the organs of the _______ system.

• A. endocrine
• B. skeletal
• C. superior to
• D. inferior to

Correct answer: C

Rationale: Blood cells are produced in the organs of the hematopoietic system. The correct answer is 'superior to' as this refers to the location of the organs responsible for blood cell production, typically bone marrow found in bones such as the vertebrae, ribs, and skull. 'Endocrine' (Choice A) refers to a different system responsible for hormone production. 'Skeletal' (Choice B) relates to bones but not specifically to the production of blood cells. Choices C and D, 'superior to' and 'inferior to,' do not make sense in the context of blood cell production and are incorrect.
