The correct Answer is:
To solve the question regarding the level at which the trachea divides, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Anatomy of the Trachea**: - The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi of the lungs. 2. **Identify the Location of Division**: - The trachea extends down into the thoracic cavity and typically divides into the right and left bronchi. 3. **Locate the Division Point**: - The division of the trachea occurs at a specific vertebral level in the thoracic region. 4. **Know the Vertebral Levels**: - The options given are: - Third cervical vertebra (C3) - Fifth cervical vertebra (C5) - Fifth thoracic vertebra (T5) - Twelfth thoracic vertebra (T12) 5. **Determine the Correct Answer**: - The trachea divides at the level of the fifth thoracic vertebra (T5). This is a well-established anatomical fact. 6. **Select the Correct Option**: - Based on the information, the correct answer is the fifth thoracic vertebra (T5). ### Final Answer: The trachea divides at the level of the **fifth thoracic vertebra (T5)**. ---
