Study Notes
Larynx Anatomy Overview
- The larynx is a crucial structure in the respiratory system, aiding in voice production and protecting the airway during swallowing.
Epiglottis
- A leaf-shaped flap that covers the trachea during swallowing to prevent food and liquids from entering the airway.
- Plays a vital role in directing food to the esophagus and air to the lungs.
Hyoid Bone
- A U-shaped bone in the neck that supports the tongue and is the only bone in the human body not directly attached to other bones.
- Serves as an anchor point for muscles involved in swallowing and speech.
Thyroid Cartilage
- The largest cartilage of the larynx, commonly referred to as the Adam's apple.
- Provides structure to the larynx and protects the vocal cords, located just below the hyoid bone.
Cricoid Cartilage
- A ring-shaped cartilage located below the thyroid cartilage, it is the only complete circular cartilage in the respiratory tract.
- Acts as a base for the larynx and helps maintain airway patency.
Trachea
- Also known as the windpipe, this tube extends from the larynx to the bronchi, allowing air passage to and from the lungs.
- Composed of C-shaped cartilaginous rings that prevent collapse while allowing flexion.
Epiglottis (Back View)
- The back view reveals the epiglottis’ position relative to the larynx, emphasizing its role in airway protection during swallowing.
Thyroid Cartilage (Back View)
- Observing the thyroid cartilage from the back highlights its prominence and the attachment points for surrounding muscles and ligaments.
Hyoid Bone (Back View)
- The back view showcases the hyoid's unique structure and its placement in the neck, reinforcing its support role for muscle attachments in the larynx and tongue.
Vocal Cords
- Also known as vocal folds, they are located within the larynx, crucial for sound production during phonation.
- Vibrate when air from the lungs passes through, allowing for voice modulation and pitch variation.
