Everyone has two vocal cords in his or her larynx (voicebox). The vocal cords vibrate during speech to produce voice. If one or both vocal cords are unable to move then the person will experience voice problems and possibly breathing and swallowing problems. This is vocal cord paralysis. For diagnosing this, doctors perform a laryngoscopy, taking a look at the two happy fellas in your throat. However, in the photo you can see a young female singer in her 20s with normal vocal cords, viewed during the midportion of stroboscopy and during breathing in. 📸•Medicogram•
