1. Skeletal muscles are attached to bones by tough connective tissues called

• A. Ligaments
• B. Tendons
• C. Cartilage
• D. Fascia

Correct answer: B

Rationale: Skeletal muscles are attached to bones by tough connective tissues called tendons. Tendons are strong, fibrous cords that connect muscles to bones, allowing for movement and stability in the body. Ligaments (option A) connect bones to other bones, not muscles to bones. Cartilage (option C) is firm and flexible connective tissue found in various parts of the body, but it does not attach muscles to bones. Fascia (option D) is a connective tissue that surrounds muscles, providing support and protection, but it does not directly attach muscles to bones.

2. Which of the following hormones is primarily responsible for regulating metabolism?

• A. Insulin
• B. Testosterone
• C. Adrenaline
• D. Thyroid hormone

Correct answer: D

Rationale: Thyroid hormone is the correct answer as it is primarily responsible for regulating metabolism. It plays a crucial role in controlling the body's metabolic rate, affecting how the body uses energy from food. Thyroid hormone levels can influence metabolism, energy production, and body weight regulation. Insulin, choice A, is involved in regulating blood sugar levels, not directly metabolism. Testosterone, choice B, is a sex hormone that primarily affects the development of male reproductive tissues. Adrenaline, choice C, is involved in the fight-or-flight response and not primarily responsible for regulating metabolism.

3. What is the sensory threshold?

• A. The smallest amount of stimulus required for an individual to feel a sensation
• B. The amount of stimulus required for an individual to feel pain
• C. The amount of stimulus required to cause an individual to move away from the stimulus
• D. The place from which the stimulus is coming

Correct answer: A

Rationale: The sensory threshold refers to the smallest amount of stimulus required for an individual to perceive or feel a sensation. It is the minimum level of stimulus intensity that is detectable by an individual. Choice B is incorrect because the sensory threshold is not specifically related to feeling pain but rather to perceiving any sensation. Choice C is incorrect as the sensory threshold is about perception and not necessarily physical reaction. Choice D is incorrect as it describes the source of the stimulus, not the threshold for perception.

4. What term describes the front of the body, for example, the kneecap?

• A. Posterior
• B. Anterior
• C. Superior
• D. Inferior

Correct answer: B

Rationale: The correct answer is 'B: Anterior.' In anatomy, 'anterior' refers to the front of the body, like the kneecap. On the other hand, 'posterior' describes the back of the body. Choices 'C: Superior' and 'D: Inferior' relate to structures being above or below a reference point, respectively, and are not used to describe the front or back of the body. Therefore, 'Anterior' is the most appropriate term given the context provided in the question.

5. Which of the following anatomical terms is not part of the knee?

• A. Medial collateral ligament
• B. Patella
• C. Lateral malleolus
• D. Lateral meniscus

Correct answer: C

Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.
