1. 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.

2. Which part of the brain is responsible for processing emotions?

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

Correct answer: B

Rationale: The correct answer is the amygdala. It is a small, almond-shaped structure located within the temporal lobe of the brain. The amygdala plays a crucial role in processing emotions such as fear, anger, pleasure, and other emotional responses. It is involved in the formation of emotional memories and helps regulate emotional responses to various stimuli. The frontal lobe is mainly responsible for higher cognitive functions such as decision-making and problem-solving, not processing emotions. The parietal lobe is involved in processing sensory information and spatial awareness, while the occipital lobe is primarily responsible for processing visual information.

3. Which of the following locations is not involved in the release of hormones during stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not involved in the release of hormones during stress. It is responsible for regulating calcium levels in the blood by secreting parathyroid hormone. During stress, the adrenal cortex, posterior pituitary, and hypothalamus play crucial roles in releasing stress hormones like cortisol, adrenaline, and oxytocin. Therefore, the correct answer is the parathyroid gland, as it is not directly associated with the release of stress-related hormones.

4. Which of the following is known as the production of red blood cells?

• A. Thrombopoiesis
• B. Erythropoiesis
• C. Hematopoiesis
• D. Phagocytosis

Correct answer: B

Rationale: Erythropoiesis specifically refers to the process of producing red blood cells (erythrocytes) in the bone marrow. Hematopoiesis is the broader term that encompasses the production of all types of blood cells, including red blood cells, white blood cells, and platelets. Phagocytosis is the process by which cells engulf and digest particles, while thrombopoiesis is the production of platelets. Therefore, the correct answer is B as it directly relates to the production of red blood cells.

5. Which vitamin is essential for the clotting of blood?

• A. Vitamin A
• B. Vitamin K
• C. Vitamin C
• D. Vitamin D

Correct answer: B

Rationale: Vitamin K is essential for the synthesis of proteins required for blood clotting. It specifically assists in the activation of clotting factors to prevent excessive bleeding from injuries. Vitamin K plays a crucial role in maintaining a balance between clotting and bleeding in the body. Choices A, C, and D are incorrect. Vitamin A is important for vision, immune function, and skin health. Vitamin C is essential for collagen synthesis and acts as an antioxidant. Vitamin D is crucial for calcium absorption and bone health.
