| What is the primary way to control frequency? |
|
Definition
| The Cricothyroid contracts and stretches the vocal folds creating tension. This increases the F0 or Fundamental Frequency, therefore increasing pitch perception. |
|
|
Term
|
Definition
| The thyroarytenoid muscle increases relaxation of the vocal fold leading to an increase of mass of the vocal fold therefore decreasing the pitch. |

Term
| What does TA active contraction mean? |
|
Definition
The cricothyroid has to achieve full contraction then Contracting the TA Active while the CT is contracted.
Increase tension
Increase F0
Increase vibration of the VF |
|
|
Term
| What is the secondary way to increase pitch? |
|
Definition
By increasing loudness it increases the lateral stretch of the VF therefore increasing tension which leads to an increase of F0 which is the rate of vibration of the VF.
The laryngeal elevators raise the larynx up and shorten the vocal tract to creating a higher pitch perception. |

Term
| What is a primary way to increase intensity? |
|
Definition
Subglottal Pressure. Ps
Take a deep breath build pressure then push the air out. |

Term
| How do you define abduction of the vocal folds? |
|
Definition
| THe vocal folds are pulled to the lateral sides. |
|
|
Term
| How is the vocal process during abduction? |
|
Definition
The vocal process is Superior Lateral and Posterior
It primarily rocks and rotates. |
|
|
Term
| What happens to the Vocal Folds during adduction? |
|
Definition
The VF move medial closing the glottal space. The arytenoid moves Anterior Inferior and Medial.
