1. The cheekbones are positioned ___________ to the nose.

• A. anterior
• B. proximal
• C. deep
• D. lateral

Correct answer: D

Rationale: The term 'lateral' refers to the direction away from the midline of the body. In this case, the cheekbones are situated to the sides of the nose, making them lateral to the nose. Therefore, 'lateral' correctly describes the position of the cheekbones in relation to the nose. Choices A, B, and C are incorrect: A. 'Anterior' means situated at or towards the front, which is not the correct description of the cheekbones in relation to the nose. B. 'Proximal' means situated nearer to the center of the body, which is not the correct description of the cheekbones' position in relation to the nose. C. 'Deep' refers to being situated further away from the surface, which is not the appropriate term to describe the cheekbones' position in relation to the nose.

2. 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.

3. Where is a herniated lumbar disc most likely to cause pain?

• A. Along the radial nerve
• B. Within the spinal cord
• C. Along the sciatic nerve
• D. Along the tibial nerve

Correct answer: C

Rationale: A herniated lumbar disc is most likely to cause pain along the sciatic nerve. The sciatic nerve is a long nerve that extends from the lower back down the back of each leg. Compression of the sciatic nerve by a herniated disc can lead to symptoms such as pain, numbness, tingling, or weakness that radiates down the leg. This condition is commonly referred to as sciatica. Choices A, B, and D are incorrect because a herniated lumbar disc typically affects the sciatic nerve, not the radial nerve, spinal cord, or tibial nerve.

4. Which of the following is a structure found in the upper respiratory tract?

• A. Larynx
• B. Pharynx
• C. Esophagus
• D. Trachea

Correct answer: B

Rationale: The pharynx is indeed a structure located in the upper respiratory tract. It acts as a common passageway for both air heading to the lungs and food traveling to the esophagus, making it a vital structure for breathing and swallowing functions. The larynx, trachea, and esophagus are also part of the respiratory and digestive systems but are not specifically located in the upper respiratory tract. The larynx is situated below the pharynx, while the trachea is found below the larynx, and the esophagus is part of the digestive system, not the respiratory tract.

5. How does a sagittal section divide the body?

• A. Into right and left regions
• B. Into upper and lower regions
• C. Into front and back regions
• D. Between the dorsal and ventral cavities

Correct answer: A

Rationale: A sagittal section divides the body into right and left regions. This type of section runs longitudinally from front to back, separating the body into right and left halves. Sagittal sections are crucial for understanding the anatomical structure and orientation of various body parts. Choices B, C, and D are incorrect because a sagittal section specifically divides the body into right and left portions, not upper and lower regions, front and back regions, or between the dorsal and ventral cavities.
