The thyroi cartilage Flashcards
The Thyroid Cartilage is made up of
Is hyaline cartilage
- The Thyroid Cartilage forms
anterior and lateral walls of larynx
- Anterior surface of hyaline cartilage is called
laryngeal prominence, or Adam’s apple
Thyroid cartilage ligaments attach to
hyoid bone, epiglottis, and laryngeal promminance
The Cricoid Cartilags is composed of
hyaline cartilage
The Cricoid Cartilage forms posterior
posterior portion of larynx
- The Cricoid Cartilage ligaments attach
to first tracheal cartilage
The Cricoid Cartilage Articulates with AC
arytenoid cartilages
The Epiglottis is Composed of
elastic cartilage
The Epiglottiis ligaments attach to
thyroid cartilage and hyoid bone
Thyroid and cricoid cartilages support and protect:
The glottis
* The entrance to trachea
- During swallowing
The larynx is elevated
* The epiglottis folds back over glottis
Cartilage prevents
entry of food and liquids into respiratory
tract
The Larynx Contains Three Pairs of Smaller
Hyaline Cartilages
- Arytenoid cartilages
- Corniculate cartilages
- Cuneiform cartilage
Corniculate and arytenoid cartilages function in opening and closing
Opening and closing of glottis
* Production of sound
