1. 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.'

2. Which part of the brain is responsible for memory and learning?

• A. Frontal lobe
• B. Temporal lobe
• C. Parietal lobe
• D. Occipital lobe

Correct answer: B

Rationale: The correct answer is B: Temporal lobe. The temporal lobe of the brain plays a crucial role in processing auditory information, memory formation, and learning. It contains the hippocampus, a structure vital for the formation of new memories and the conversion of short-term memories into long-term ones. Damage to the temporal lobe can lead to memory impairments and difficulties in learning new information. Choices A, C, and D are incorrect because the frontal lobe is primarily involved in decision making, problem-solving, and emotional control; the parietal lobe is responsible for sensory processing and spatial orientation; and the occipital lobe is mainly dedicated to visual processing and interpretation.

3. The coronal plane of the body may also be called the ___________ plane.

• A. sagittal
• B. median
• C. frontal
• D. axial

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.

4. What type of tissue forms the outer layer of the skin?

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

Correct answer: B

Rationale: Epithelial tissue is the correct answer. It forms the outer layer of the skin, serving as a protective barrier against pathogens and environmental damage. This tissue type is essential for maintaining skin integrity and plays a crucial role in skin function. Connective tissue (Choice A), although important for providing support and structure, does not form the outer layer of the skin. Muscle tissue (Choice C) is responsible for movement and is not the primary tissue in the skin. Nervous tissue (Choice D) is involved in transmitting signals but is not the main component of the skin's outer layer.

5. Where will a person who has damage to their ulnar nerve experience decreased sensation?

• A. Leg
• B. Arm
• C. Face
• D. Abdomen

Correct answer: B

Rationale: The ulnar nerve innervates the forearm and hand, specifically providing sensation to the ring and little fingers. Damage to this nerve can lead to decreased sensation in these areas, making the arm the correct answer. Choices A, C, and D are incorrect because the ulnar nerve does not supply sensation to the leg, face, or abdomen.
