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. Which bone does not articulate with any other bone in the body?

• A. Scapula
• B. Hyoid
• C. Radius
• D. Femur

Correct answer: B

Rationale: The correct answer is B: Hyoid. The hyoid bone is the only bone in the body that does not articulate with any other bones. It is located in the neck and supports the tongue and other muscles involved in swallowing and speech. The scapula articulates with the clavicle and humerus, the radius with the ulna and humerus, and the femur with the pelvis and tibia. Choices A, C, and D are incorrect because they all articulate with other bones in the body.

3. Which type of blood vessel carries blood back to the heart?

• A. Arteries
• B. Capillaries
• C. Veins
• D. Lymphatic vessels

Correct answer: C

Rationale: Veins are the blood vessels that carry deoxygenated blood back to the heart, except for the pulmonary veins which carry oxygenated blood from the lungs. Arteries carry oxygenated blood away from the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues but do not specifically carry blood back to the heart. Lymphatic vessels are part of the lymphatic system responsible for immune function and do not directly carry blood back to the heart. Therefore, the correct answer is veins.

4. Which is another name for thiamine?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B6
• D. Vitamin D

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.

5. Which hormone is not produced by the pituitary gland?

• A. FSH
• B. TRH
• C. LH
• D. ADH

Correct answer: B

Rationale: Thyrotropin-releasing hormone (TRH) is not produced by the pituitary gland. TRH is actually produced by the hypothalamus and acts on the pituitary gland to stimulate the release of thyroid-stimulating hormone (TSH). On the other hand, FSH (follicle-stimulating hormone), LH (luteinizing hormone), and ADH (antidiuretic hormone) are all hormones directly produced by the pituitary gland.
