1. What is true about caloric intake for the average person?

• A. It should increase with age.
• B. It should decline and then increase with age.
• C. It should decline with age.
• D. It should remain constant over a lifetime.

Correct answer: C

Rationale: Caloric intake for the average person typically declines with age due to factors such as changes in metabolism, muscle mass, and physical activity levels. As people age, their metabolism tends to slow down, and they may also experience a decrease in muscle mass and physical activity, leading to a reduced need for calories. Option A is incorrect because caloric intake generally decreases rather than increases with age. Option B is incorrect as it suggests a fluctuation in caloric intake that is not typically seen. Option D is incorrect as caloric needs usually change over a person's lifetime due to various factors.

2. Enlargement of the thyroid, commonly known as a goiter, might be expected to affect ___________.

• A. swallowing
• B. insulin levels
• C. sleep
• D. digestion

Correct answer: A

Rationale: Enlargement of the thyroid, known as a goiter, can compress the nearby structures in the neck, including the esophagus. This compression can lead to symptoms such as difficulty swallowing (dysphagia) or a sensation of pressure in the throat. Therefore, an enlarged thyroid gland is expected to affect swallowing. Choices B, C, and D are incorrect because a goiter primarily affects structures in the neck due to its physical enlargement, rather than directly impacting insulin levels, sleep, or digestion.

3. The coronal plane of the body may also be called the ___________ plane.

• A. sagittal
• B. median
• C. frontal
• D. axial

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.

4. Which type of tissue connects bones to other bones?

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

Correct answer: B

Rationale: The correct answer is B: Ligaments. Ligaments are tough, flexible connective tissues that connect bones to other bones, providing stability and support to joints. Tendons (choice A) connect muscles to bones, enabling movement. Cartilage (choice C) is a firm, rubbery material that cushions bones at joints. Muscles (choice D) are contractile tissues responsible for movement. Therefore, when looking for the tissue that connects bones to other bones, ligaments are the most appropriate choice.

5. Which type of muscle is found in the heart?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Striated muscle

Correct answer: B

Rationale: Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for the rhythmic contractions that pump blood throughout the body. Unlike smooth and skeletal muscle, cardiac muscle has its own unique structure and function to meet the demands of the heart's continuous pumping action. Smooth muscle is found in the walls of internal organs and blood vessels, not in the heart. Skeletal muscle is attached to bones and helps in movement but is not found in the heart. Striated muscle is a broader term that includes both cardiac and skeletal muscle, but specifically, cardiac muscle refers to the muscle tissue of the heart.
