1. What substance makes up the pads that provide support between the vertebrae?

Correct answer: B

Rationale: Cartilage is the correct answer as it is the substance that makes up the pads between the vertebrae. Cartilage provides cushioning and support between the bones of the spine, allowing for flexibility and preventing friction between the vertebrae. Bone (choice A) is incorrect as it forms the structure of the vertebrae, not the intervertebral discs. Tendon (choice C) is incorrect as it connects muscle to bone and is not found between the vertebrae. Fat (choice D) is incorrect as it is not the substance that makes up the pads between the vertebrae.

2. Which is another name for thiamine?

Correct answer: A

Rationale: Thiamine is another name for Vitamin B1. It is an essential vitamin that plays a crucial role in energy metabolism and is important for the proper functioning of the nervous system. Vitamin B2 is riboflavin, not thiamine. Vitamin B6 is pyridoxine, not thiamine. Vitamin D is a different vitamin responsible for calcium absorption and bone health, not thiamine. Therefore, the correct answer is Vitamin B1.

3. To which two systems does the urethra belong?

Correct answer: B

Rationale: The urethra belongs to both the urinary and reproductive systems. In the urinary system, it functions as a passage for urine from the bladder to exit the body. In the reproductive system, it serves as a conduit for the expulsion of semen during ejaculation. Choice A is incorrect because the urethra is not part of the endocrine system. Choice C is also incorrect because the urethra is not primarily associated with the endocrine system. Choice D is incorrect as the urethra is not part of the digestive or cardiovascular systems.

4. The orthopedic surgeon informs you that you have broken the middle region of the humerus. What area is he describing?

Correct answer: D

Rationale: The diaphysis is the correct answer in this scenario. It refers to the middle or shaft region of a long bone like the humerus. The epiphysis is the end of a long bone, while articular cartilage is the smooth tissue covering the ends of bones at a joint. The perichondrium is the dense irregular connective tissue that surrounds cartilage.

5. Which of the following is not part of the body’s secondary defense system?

Correct answer: D

Rationale: Cilia are not part of the body's secondary defense system. They are hair-like structures primarily involved in movement and transporting substances across cell surfaces, such as in the respiratory tract for debris and pathogen removal. However, cilia do not play a direct role in the immune response mechanisms characteristic of the body's secondary defense system. Macrophages, leukocytes, and T cells are immune cells that actively participate in the secondary defense system by targeting and eliminating pathogens.
