How the CricoThyroid muscle change phonation pitch

by National Center for Voice and Speech

This very brief (1 minute) video shows a demonstration of the action of the cricothyroid muscle in elongating and thinning the vocal folds, using an excised cow larynx.

Resource Type: Video

Resource Name: National Center for Voice and Speech

Level: Intermediate

Category: Anatomy & Physiology

Keywords: Pitch, CT, Cricothyroid, Larynx, Muscle

Reviews

Editor's Review

Very helpful "3-D" view of anatomy, but the viewer should already be able to identify the cricothyroid muscle, or have a diagram nearby, before viewing.
