• C. The restaurant offers a variety of dishes (including vegetarian options).

3. The epiglottis is a small flap of cartilage located near the base of the tongue. What is its role during swallowing?

• A. Initiates the swallowing reflex
• B. Grinds food into smaller pieces
• C. Covers the trachea to prevent food aspiration
• D. Stores saliva for lubrication

Correct answer: C

Rationale: The epiglottis is a crucial anatomical structure that covers the trachea during swallowing to prevent food aspiration. When we swallow, the epiglottis folds over the trachea, directing food and liquids down the esophagus instead of entering the airway. This action helps to ensure that the food and liquids go to the stomach for digestion and not into the lungs, which can lead to aspiration pneumonia, a serious condition. Therefore, option C, 'Covers the trachea to prevent food aspiration,' is the correct role of the epiglottis during swallowing.

Rationale: The correct answer is B: Autonomic nervous system. The autonomic nervous system is responsible for regulating involuntary functions in the body, such as heart rate, digestion, respiratory rate, and other automatic processes. The somatic nervous system (A) controls voluntary muscle movements, the peripheral nervous system (C) consists of nerves outside the brain and spinal cord, and the central nervous system (D) includes the brain and spinal cord. Understanding the functions and divisions of the nervous system is crucial for grasping how different bodily processes are controlled and regulated.
