This section provides high-yield, exam-oriented notes on the **larynx and trachea**, structured specifically for **MBBS and ENT students**. ### What are the Larynx and Trachea? The **larynx**, also known as the voice box, is a complex structure involved in **phonation, respiration, and airway protection**. It contains the **vocal cords**, is responsible for producing sound, and plays a crucial role in **swallowing and preventing aspiration**. The **trachea** is a cartilaginous airway tube that begins just below the larynx and extends into the thorax, where it divides into the bronchi. It serves as a vital conduit for air passage to the lungs. Together, the larynx and trachea form an essential segment of the upper airway. A strong grasp of their anatomy and function is crucial for diagnosing and managing conditions such as **Laryngeal tumors**, **Stridor and airway obstruction**, **Laryngitis**, **Tracheostomy and airway interventions**, **Voice disorders**, **Subglottic stenosis**. --- In this section, you'll find well-organized notes covering: - Anatomy of Larynx and Trachea - Laryngeal cartilages, joints, and membranes - Intrinsic and extrinsic muscles of Larynx - Nerve supply of Larynx (including recurrent and superior laryngeal nerves) - Lymphatic drainage of Larynx - Histology and mucosal lining of Larynx - Differences between infant and adult larynx - Clinical and surgical relevance - Diseases of Larynx and Trachea - Surgeries of Larynx and Trachea These notes are designed to offer **conceptual clarity**, help with **viva preparation**, and support **quick last-minute revision**.
