Phonatory System Anatomy: Overview and location

what is the role of the phonatory system and how does it do it?

sound source. By using air under pressure to produce phonation

phonation

generation of voiced sound through the larynx

Based on _________ phonatory system produces ______, sounds that can be perceived or heard

aeromechanical events, acoustic products

what are the speech functions of the phonatory system

producing: voiced sounds= phonation. Voiceless sounds= non phonated

Modifying: vocal pitch and loudness

Influencing: voice quality

what are the biological functions of the phonatory system

- prevent air from escaping ex: holding breath under water
- prevent foreign substances from entering lungs
- expel foreign substances from lungs

What can we see in a Laryngoscopic (or endoscopic) view of larynx

When coughing: air pressure builds and then we release it. So larynx first closes when coughing and then releases.

Where is the larynx located?

on top of trachea, perfect place for biological purposes

Where is the larynx between?

Upper and lower respiratory tracts

Why is it good position for the larynx sit on top of the trachea

1) producing voiced/voiceless sounds. And
2) controlling and protecting airway
