What are the Cartilage components of the Larynx? | 1. Thyroid Cartilage; 2. Epiglottis; 3. Cricoid Cartilage; 4. Arytenoid Cartilages |
What is the function of the Thyroid Cartilage of the Larynx? | AMPLIFIES Voice |
What is the function of the Epiglottis of the Larynx? | DEFLECTS food into the Esophagus |
What is the composition of the Epiglottis? | Elastic Cartilage |
What is the function of the Cricoid Cartilage of the Larynx? | holds Arytenoids |
What is the composition of the Cricoid Cartilage? | Hyaline Cartilage |
What is the function of the Arytenoid Cartilages of the Larynx? | changes TENSION on Vocal Chords --> pitch |
What are the Membranous components of the Larynx? | 1. Ventricular Folds; 2. Vocal Chords |
Where are the Ventricular Folds located? | Bi-Lateral to the Vocal Cords |
What is the composition of the Ventricular Folds? | Dense, Regular Connective Tissue |
What is the function of the Ventricular Folds? | divert air through the Glottis to Vocal Cords |
What is the medial margin between the Vocal Cords? | Glottis |
Why do men have a deeper voice? | their Vocal Cords are THICKER |
What is the function of the Vocal Cords? | to VIBRATE as air moves across them to create SOUND |
What is the function of the Glottis? | to deflect food that made its way passed the Epiglottis |
What are the Muscle Components of the Larynx? | 1. Intrinsic Muscles; 2. Extrinsic Muscles |
What is the function of the Intrinsic Muscles of the Larynx? | 1. CLOSE Glottis; 2. control TENSION on Vocal Cords --> determining pitch of sound |
