The Larynx: Structure and Functions

Location and Function

• Located at the top of the trachea (windpipe)
• Also known as the voice box
• Plays a crucial role in breathing, eating, and speaking

Structure

• Consists of cartilage and muscle
• Made up of two pairs of folds:
  • True vocal cords (vocal folds): produce sound when vibrating
  • False vocal cords (vestibular folds): protect the true vocal cords and aid in breathing

Functions

• Produces sound for speaking and singing
• Regulates airflow during breathing
• Prevents food and liquids from entering the lungs during swallowing

Muscles of the Larynx

• Intrinsic muscles: control vocal cord movement and tension
• Extrinsic muscles: move the larynx up and down during swallowing and speaking

Importance of the Larynx

• Essential for communication and expression
• Crucial for breathing and eating
• Any damage or disorders can lead to significant communication and respiratory issues
