Where carbon dioxide and oxygen take place |
|
|
Quiet breathing |
Equal inspiration and expiration times Expiration passive |
|
|
Speech breathing |
Lungs increased to a larger volume Expiratory phase is longer- maintain constant subglottal pressure Drives vocal cords |

|
What is the larynx |
Air valve also called the voice box Made of cartilage, membranes, muscles, connective tissue and bone |
|
|
What are the three functions of the larynx? |
Protection of airway: prevents food from going n into lungs Phonation: conversion of respiratory energy into sound energy (voicing) Permits us to perform intensive muscular actions (grunting) |
|
|

Epiglottis Hyoid bone Thyroid cartilage Laryngeal prominence Arytenoid cartilage Cricoid cartilage Trachea |
|
|
Hyoid bone |
Above thyroid cartilage Horseshoe shaped Free floating Found very high on neck Point of attachment for muscles of tongue and larynx |
|
|
Cricoid cartilage |
Sits on trachea |
|
|
Thyroid cartilage |
Forms the Adams apple Largest |
|
|
Arytenoids |
Allows you to open and close vocal cords |
|
|
Epiglottis |
Leaf like structure that sits below Adams apple Keeps food from going into lungs More for swallowing than speech production |
|
|
False folds |
Protect true folds Make deep Barotone sounds |
