Anatomy

1. Calcitonin, a hormone that helps regulate calcium levels, is produced by the:

Correct answer: A

Rationale: The correct answer is A: "Thyroid gland." Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. It works in opposition to parathyroid hormone, which is produced by the parathyroid gland. The thymus gland is responsible for immune function, while the adrenal gland produces hormones like cortisol and adrenaline. Therefore, the thyroid gland is the specific gland responsible for producing calcitonin to regulate calcium levels in the body.

2. Which sentence uses comma splices incorrectly?

Correct answer: C

Rationale: Option (c) incorrectly combines two independent clauses with only a comma. A semicolon or conjunction is needed

3. Muscles that work together to produce a specific movement are called

Correct answer: C

Rationale: Synergistic muscles are the correct answer because they are muscles that work together to produce a specific movement. These muscles coordinate their actions to achieve a common goal, such as bending the elbow or extending the knee. Antagonistic muscles work in opposition to each other, while agonistic muscles are the primary movers in a particular movement. Flexors and extensors refer to specific muscle groups that perform opposing actions, rather than working together synergistically. Understanding the concept of synergistic muscles is essential in biomechanics and exercise science.

4. Which phrase best describes the tone of the following sentence: "He slammed his fist on the table, his voice booming with anger."

Correct answer: C

Rationale: The verbs and descriptive language convey strong emotions and agitation.

5. Which of the following is NOT a major component of a healthy blood pressure reading?

Correct answer: A

Rationale: The correct answer is A. Systolic pressure is a major component of a healthy blood pressure reading as it represents the peak pressure in the arteries during ventricular contraction. Diastolic pressure, representing the pressure in the arteries during ventricular relaxation, is also a key component. Pulse pressure, the difference between systolic and diastolic pressure, provides additional information about the cardiovascular system. Blood oxygen saturation, while important for overall health, is not directly measured in a blood pressure reading. Therefore, it is not a major component of a healthy blood pressure reading.

6. You need to buy cardboard to cover a rectangular box with dimensions 40cm by 30cm by 25cm. Considering only the exterior surfaces (not flaps or openings), how much cardboard do you need (assume one sheet covers 0.5 sq m)?

Correct answer: C

Rationale: Calculate the areas of each side and add them up for the total surface area. Divide by the coverage area per sheet to determine the number of sheets needed.
