Anatomy

1. The moon-shaped white structures at the base of fingernails are called:

Correct answer: A

Rationale: The correct answer is A, "Lunulae." The moon-shaped white structures at the base of fingernails are called lunulae. These are most visible on the thumb and are the visible part of the nail matrix. The lunulae appear white because the nail matrix underneath is not visible due to its thickness. Cuticle (B) refers to the thin layer of skin at the base of the nail, hyponychium (C) is the skin located under the free edge of the nail, and matrix (D) is the tissue at the base of the nail where growth occurs. Therefore, the correct term for the moon-shaped white structures is lunulae.

2. What is the ethical concern surrounding genetic engineering?

Correct answer: D

Rationale: Rationale: A) Risk of introducing new diseases: Genetic engineering involves manipulating the genetic material of organisms, which can potentially lead to the creation of new diseases or the spread of existing ones in unintended ways. This risk raises ethical concerns about the potential harm to human health and the environment. B) Potential for misuse and discrimination: Genetic engineering technologies can be misused for purposes such as creating biological weapons or enhancing certain traits in individuals, leading to discrimination based on genetic makeup. This raises ethical concerns about fairness, justice, and the potential for societal harm. C) Unforeseen consequences on ecosystems: Genetic engineering can have unintended consequences on ecosystems, such as disrupting natural balances or harming biodiversity. These unforeseen impacts raise ethical concerns about the responsibility of scientists and policymakers to consider the long-term effects of genetic modifications on th

3. Julius stresses the importance of promoting ‘esprit d corps’ among the members of the unit.

Correct answer: D

Rationale: The correct answer is D because it emphasizes the idea of collective effort and striving for excellence, which aligns with promoting 'esprit de corps' - a sense of unity and camaraderie among group members. By working together and combining their efforts, the unit can enhance the quality of care they provide. This fosters a positive team spirit and encourages collaboration. The other options do not directly address the concept of 'esprit de corps' or the importance of unity and teamwork within the group.

4. What is the relationship between work and the displacement of an object?

Correct answer:

Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.

5. Which of the following is the main function of the liver?

Correct answer: D

Rationale: Rationale: A) The liver does produce bile, which helps in the digestion of fats, but this is not its main function. Bile is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. B) While the liver does store energy in the form of glycogen, this is not its main function. Glycogen is a form of glucose storage that can be broken down into glucose when the body needs energy. C) The liver does produce proteins that help to clot blood, such as fibrinogen and prothrombin, but this is not its main function. These proteins are essential for the blood clotting process to prevent excessive bleeding. D) The main function of the liver is to detoxify harmful substances in the body. The liver processes and removes toxins, drugs, alcohol, and other harmful substances from the bloodstream, making them less harmful and

6. During normal breathing, which muscle is the primary driver of inhalation by contracting and flattening to increase the volume of the thoracic cavity?

Correct answer: A

Rationale: The diaphragm is the primary muscle responsible for inhalation during normal breathing. When the diaphragm contracts and flattens, it increases the volume of the thoracic cavity, creating a negative pressure that allows air to rush into the lungs. The intercostal muscles also play a role in expanding the ribcage to assist with inhalation. However, the diaphragm is the main driver of the breathing process by creating the necessary space for the lungs to expand and fill with air.
