Need to remember

What connects the arytenoid cartilage to the cricoid cartilage?

Synovial joint

The anterior part of the arytenoid does what?

Anterior part of the arytenoid is the Vocal process and connects to the VF

The Posterior part of the arytenoid does what?

Posterior part is the Muscular process and connects laterally

Throarytenoid ( Three things)

-The “Body” of the vocal fold

-Botox is added the this to help prevent contraction of the muscles

-Helps with abduction

What muscles are part of the abduction muscles?

-Thoarytenoid

-Crortenoid

-Posterior cricodthryoid

Where is the true vocal fold located compared to the false?

The false vocal fold is located above the true VF

The body of the vocal fold allows us to do what?

hange the mechanical characteristics, changes the loudness and shape of the VF

Quiet Respiration

Flatten of the Diaphragm and External intercostals only

Inspiration Respiration

initiated at FRC

volume in the lungs after a passive expiration

Quiet Expiration

Passive process

Resting Tidal Volume

Quiet Breathing

What are the Biological functions of the Larynx?

Normal breathing, Forced breathing, Swallowing, coughing and sneezing

What does the larynx have a biological role in?

Swallowing

Forced Respiration

Energy in muscles increase or Aerodynamic forces come in

What muscles are being used durning Forced respiration?

additional muscles of inspiration are activated to assist the Diaphragm and external intercostal

What are the main purpose of Biological function ( not the 5 ones but?)

-controlling the size of the glottis for breathing g

-protecting the air way from swallowing

-coughing and sneezing by allowing a big puff to come out

Speech Breathing

Is used to create and maintain enough air pressure to drive the vocal folds and force air past obstruction and through constrictions

What is good Technique when Wanting Effective speech Breathing?

-Intate the utterance at 60%

-terminate the utterance at 40%

Inhale the FRC from 40%-60%

What are the steps for when you are speaking , the rib cage, lung pressure, etc? 4 Steps!

Rib cage elevated, Slowly it decreases, air pressure is maintained, lung volume is highest at the begging of utterance and lowers well speaking

What is the Thoracic cavity?

Everything in the Rib cage

-Respiratory system and pulmonary system

Pulmonary system

How we stay alive from breathing stand point , the mechanism by which we exchange gases , by getting oxygen In and carbon out

When weinhale what happens to thoratic cavity?

Dropping the floor of the thoratic cavity increasing the vertical space of thoracic cavity

What does the Rib cage do durning Inhalation?

Lifting the rib cage as well as flaring out

-Overall expansion of thoratic cavity

What are the purposes of all abdominals muscles?

Contraction provides strong compression of the abdomen muscles

Fundamental Frequency

Number of cycles per second (HZ or Hertz)

To Increase the fundamental Frequency (F0)

Vf must be Stretched, Contracted and Thinner

To increase the Loudness what does the process of the VF look like?

1. Increase the Tracheal pressure

2. Fast and farther Vf’s

3. Restoring/ Snapping the Vf back Tg faster

4. Shutting the airflow off quicker

Increased Tracheal Pressure does what to the VF?

Displace (Moves) the VF farther and Faster apart from each other

-More air coming up the airway pipe (Trachea) ^

When does Hoarse Voice quality happen? What is Happening to the VF?

• Breathiness ( Airleak)

• Harshness ( irregular vibration)

When you Inhale What is Your Thoratic Cavity doing?

Gaining more space while dropping the diaphragm to flatten it

What does your Diaphragm do when you contract ( inhale) ?

Diaphram Flattens

What do the External Intercostal do?

Raise the Rib
