1. What is the name of the bone in the human thigh?

• A. Ulna
• B. Femur
• C. Radius
• D. Humerus

Correct answer: B

Rationale: The correct answer is B. Femur. The femur, also known as the thigh bone, is located in the human thigh. It is the longest and strongest bone in the human body, extending from the hip to the knee. The ulna, radius, and humerus, on the other hand, are bones found in the arm. Therefore, choices A, C, and D are incorrect as they are bones of the arm, not the thigh.

2. What is the average normal body temperature in degrees Celsius?

• A. 30°C
• B. 32°C
• C. 35°C
• D. 37°C

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.

3. Which type of joint is found in the neck and allows for rotational movement?

• A. Hinge joint
• B. Pivot joint
• C. Ball and socket joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is B: Pivot joint. A pivot joint, like the one found in the neck, allows for rotational movement, enabling the head to turn from side to side. Hinge joints (Choice A) allow movement in one plane like a door hinge and are not found in the neck. Ball and socket joints (Choice C) allow for a wide range of motion in multiple directions and are typically found in the hip and shoulder. Saddle joints (Choice D) allow for movement back and forth and side to side, like the thumb joint, but are not found in the neck.

4. A tissue examined under the microscope exhibits the following characteristics: cells found on the internal surface of the stomach, no extracellular matrix, cells tall and thin, no blood vessels in the tissue. What type of tissue is this?

• A. Epithelial
• B. Connective tissue
• C. Cartilage
• D. Nervous

Correct answer: A

Rationale: The correct answer is 'Epithelial.' Epithelial tissue is characterized by cells lining surfaces and cavities, such as the stomach. It does not contain blood vessels, and the cells are tall and thin. The absence of an extracellular matrix is typical of epithelial tissue, making it the most suitable choice in this scenario. Connective tissue, like cartilage and nervous tissue, have different characteristics that do not align with the description provided in the question.

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

• A. Epiphysis
• B. Articular cartilage
• C. Perichondrium
• D. Diaphysis

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.
