TOPIC: ANATOMY OF LARYNX
📌 INTRODUCTION:
🔹The larynx is the voice box – a short, tubular structure involved in phonation, breathing, and protection of lower airways.
🔹Extends from C3 to C6 vertebrae.
🔹Located in the anterior neck, continuous above with the laryngopharynx and below with the trachea.
1. CARTILAGES OF THE LARYNX
A. Unpaired Cartilages
Thyroid cartilage – Largest; forms Adam’s apple (laryngeal prominence).
Cricoid cartilage – Signet-ring shaped; only complete ring of airway.
Epiglottis – Leaf-shaped; prevents food from entering larynx during swallowing.
