Anatomy

1. Which skin condition is characterized by patches of inflamed, reddened skin and is often triggered by allergens or stress?

Correct answer: A

Rationale: The correct answer is A: Eczema. Eczema is a skin condition characterized by patches of inflamed, reddened skin that can be triggered by allergens or stress. It is a chronic condition that can cause itching and discomfort. Psoriasis (option B) is a different skin condition characterized by red, scaly patches on the skin. Acne (option C) is a common skin condition characterized by pimples and clogged pores. Vitiligo (option D) is a condition where the skin loses its pigment, resulting in white patches. Therefore, eczema best fits the description provided in the question.

2. An Egyptian model pyramid has a square base side length of 10cm and a height of 8cm. What is its volume?

Correct answer: D

Rationale: Use the formula for volume of a pyramid: (1/3) * base area * height. Calculate the base area (10cm * 10cm = 100 sq cm) and substitute: (1/3) * 100 sq cm * 8cm = 80 cu cm.

3. Which hormone stimulates the release of pancreatic enzymes and bile?

Correct answer: C

Rationale: The correct answer is C: Cholecystokinin (CCK). Cholecystokinin is a hormone produced by the small intestine in response to the presence of food, especially fats and proteins. It stimulates the release of pancreatic enzymes from the pancreas and bile from the gallbladder to aid in digestion. Gastrin is a hormone that stimulates the release of gastric acid in the stomach. Insulin and glucagon are hormones involved in regulating blood sugar levels, not the release of pancreatic enzymes and bile. Therefore, CCK is the hormone responsible for stimulating the release of pancreatic enzymes and bile in the digestive process.

4. Which statement accurately defines power?

Correct answer: b

Rationale: Power measures how quickly work is done or energy is transferred or converted.

5. Adipose tissue, commonly known as fat, primarily functions in:

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Adipose tissue, or fat, serves multiple functions in the body. It provides support by cushioning and protecting organs, acts as an insulation layer to maintain body temperature, and serves as a crucial energy storage site where excess energy is stored in the form of triglycerides. Therefore, all of the options listed (support, insulation, and energy storage) are accurate functions of adipose tissue.

6. Which structure surrounds individual muscle fibers, providing support and aiding in the transmission of force generated during muscle contraction?

Correct answer: b

Rationale: The correct answer is B: Endomysium. Endomysium is the connective tissue layer that surrounds individual muscle fibers within a muscle. It plays a crucial role in supporting the muscle fibers and aiding in the transmission of force generated during muscle contraction. Tendons (option A) connect muscle to bone and do not surround individual muscle fibers. Perimysium (option C) surrounds bundles of muscle fibers, while epimysium (option D) envelops the entire muscle. Therefore, endomysium is specifically responsible for surrounding and supporting individual muscle fibers, making it the most fitting answer.
