1. An anatomical section that separates the body into right and left portions is a _______ section.

• A. frontal
• B. transverse
• C. coronal
• D. sagittal

Correct answer: D

Rationale: The correct answer is 'sagittal.' A sagittal section divides the body into right and left portions. Choice A, 'frontal,' is incorrect as it divides the body into front and back portions. Choice B, 'transverse,' divides the body into upper and lower portions. Choice C, 'coronal,' divides the body into anterior and posterior portions. Therefore, 'sagittal' is the most appropriate term for a section separating the body into right and left portions.

2. Which of the following may indicate hypersecretion of thyroid hormone?

• A. weight loss
• B. Bradycardia
• C. cold intolerance
• D. lethargy

Correct answer: A

Rationale: Weight loss is a common symptom of hyperthyroidism, which is characterized by an excess secretion of thyroid hormone. This increased metabolic rate can lead to weight loss despite normal or increased appetite. Bradycardia (slow heart rate), cold intolerance, and lethargy are more commonly associated with hypothyroidism, where there is an insufficient production of thyroid hormone. Therefore, choices B, C, and D are incorrect in the context of hypersecretion of thyroid hormone.

3. Which of the following lists best illustrates the idea of increasing levels of complexity?

• A. Cells, tissues, organelles, organs, organ systems
• B. Tissues, cells, organs, organelles, organ systems
• C. Organs, organelles, organ systems, cells, tissues
• D. Organelles, cells, tissues, organs, organ systems

Correct answer: D

Rationale: The correct answer is D: Organelles, cells, tissues, organs, organ systems. This list correctly depicts the increasing levels of complexity in biological organization. It starts with organelles, which are subunits within cells, followed by cells, then tissues (groups of cells working together), organs (comprised of different tissues), and finally organ systems (multiple organs working together). Choices A, B, and C are incorrect as they do not follow the logical progression of complexity from smaller units to larger, more complex structures.

4. Do we know all there is to know about the structure and function of the human body?

• A. Yes
• B. No
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: No, the statement that we know all there is to know about the structure and function of the human body is false. The human body is complex, and there is still much to discover and understand about its intricate functions. Science and medicine continue to make new discoveries and advancements in understanding the human body. Choice A is incorrect because it claims that we know everything, which is not true. Choice C is not the best answer as it implies uncertainty rather than acknowledging the ongoing research and discoveries in this field. Choice D is not the correct option as there is a definitive answer to the question.

5. Which of the following is produced by the prostate gland?

• A. testosterone
• B. fluid to lubricate the head of the penis
• C. substance to enhance sperm mobility
• D. Gonadotrophin-releasing hormone

Correct answer: B

Rationale: The correct answer is 'fluid to lubricate the head of the penis.' The prostate gland produces a milky fluid that makes up part of the seminal fluid, which helps to nourish and transport sperm. Testosterone is produced mainly by the testes, not the prostate gland. While the prostate gland does contribute to sperm mobility, its primary function is to produce the fluid that lubricates the penis during ejaculation. Gonadotrophin-releasing hormone is produced by the hypothalamus and regulates the release of hormones from the pituitary gland.
