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 gland is known as the 'master gland'?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pineal gland

Correct answer: B

Rationale: The pituitary gland, often referred to as the 'master gland,' is the correct answer. It is responsible for regulating the release of hormones from other endocrine glands in the body. The pituitary gland controls various bodily functions and plays a crucial role in maintaining hormonal balance, making it a central and vital component of the endocrine system. The other options, such as the thyroid gland (A), adrenal gland (C), and pineal gland (D), have important functions in the endocrine system but are not specifically known as the 'master gland.'

3. What is the function of the liver in digestion?

• A. To produce bile
• B. To store glucose
• C. To secrete digestive enzymes
• D. To detoxify harmful substances

Correct answer: A

Rationale: The liver's main role in digestion is to produce bile, a substance that aids in the breakdown and absorption of fats in the small intestine. Bile emulsifies fats, helping enzymes break them down into smaller molecules for easier absorption in the digestive tract. Therefore, the correct answer is A: 'To produce bile.' Storing glucose, secreting digestive enzymes, and detoxifying harmful substances are functions of the liver, but they are not primarily related to digestion.

4. Which is a posterior feature of the human leg?

• A. Patella
• B. Quadriceps sartorius
• C. Triceps brachii
• D. Achilles tendon

Correct answer: D

Rationale: The correct answer is the Achilles tendon. The Achilles tendon is a strong tendon located at the back of the human leg, connecting the calf muscles to the heel bone. This positioning makes it a posterior feature, situated at the rear of the leg. The patella, also known as the kneecap, is positioned at the front of the leg, making it an anterior feature. The quadriceps sartorius are muscles located in the front of the thigh, not at the back of the leg. Additionally, the triceps brachii is a muscle found in the upper arm, not in the leg, making it an incorrect choice.

5. You have been given a sample tissue that has pillar-shaped cells arranged tightly together. The tissue you have is:

• A. Squamous Epithelium
• B. Cuboidal Epithelium
• C. Columnar Epithelium
• D. Transitional Epithelium

Correct answer: C

Rationale: The correct answer is C: Columnar Epithelium. Columnar epithelium is characterized by tall, pillar-like cells that are closely packed together. This arrangement allows for absorption and secretion in tissues like the digestive tract, where this type of epithelium is commonly found. Squamous epithelium (choice A) consists of flat cells, cuboidal epithelium (choice B) has cube-shaped cells, and transitional epithelium (choice D) is found in areas that need to stretch and expand, like the urinary bladder.
