1. Cartilage, a type of connective tissue, provides flexible support in various structures. Which of these structures does NOT contain cartilage?
- A. Ears
- B. Joints
- C. Muscles
- D. Nose
Correct answer: C
Rationale: Cartilage is a type of connective tissue that provides flexible support in various structures. Ears, joints, and the nose all contain cartilage. Muscles, however, are made up of muscle tissue, not cartilage. Therefore, muscles do not contain cartilage. Choice A, ears, choice B, joints, and choice D, nose, are incorrect as they all contain cartilage. Choice C, muscles, is the correct answer as muscles are not composed of cartilage.
2. Which of the following glands is responsible for regulating metabolism?
- A. Thymus
- B. Pituitary
- C. Pancreas
- D. Thyroid
Correct answer: D
Rationale: The correct answer is D, Thyroid. The thyroid gland is responsible for regulating metabolism by producing thyroid hormones. These hormones play a crucial role in controlling various metabolic processes in the body, including energy production and utilization. Choice A, Thymus, is not responsible for regulating metabolism but plays a role in the immune system. Choice B, Pituitary, regulates various hormones but not specifically focused on metabolism. Choice C, Pancreas, is involved in insulin production and blood sugar regulation but is not primarily responsible for regulating metabolism.
3. Which type of cells are found in the hair bulb and are responsible for hair growth?
- A. Basal
- B. Epidermal
- C. Epithelial
- D. Merkel
Correct answer: C
Rationale: The correct answer is C: Epithelial. The hair bulb contains actively growing epithelial cells responsible for hair growth. Basal cells are located in the basal layer of the epidermis, not specifically in the hair bulb, making choice A incorrect. Epidermal cells are part of the outer layer of the skin, so choice B is incorrect. Merkel cells are related to touch sensations in the skin, not hair growth, making choice D incorrect.
4. Classifications of human tissues exclude:
- A. Epithelial tissue
- B. Nervous tissue
- C. Adipose tissue (a specialized form of connective tissue)
- D. Bony tissue
Correct answer: D
Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.
5. What is the cycle of infection?
- A. Reservoir host, means of exit, means of transmission, means of entrance, susceptible host
- B. Entry point, transmission, replication, exit, susceptible host
- C. Susceptible host, replication, transmission, entry, exit
- D. Transmission, replication, entry, exit, susceptible host
Correct answer: A
Rationale: The correct answer is A: 'Reservoir host, means of exit, means of transmission, means of entrance, susceptible host.' This cycle of infection involves the pathogen starting in a reservoir host, exiting through a means, being transmitted to another host, entering the new host through a means, and ultimately infecting the susceptible host. Choices B, C, and D are incorrect because they do not follow the correct sequence of events in the cycle of infection.
