Al, What Dot posted is in line with what I've read about the voice..... it is also interesting that she said that the botox is not used because the tension is too tight. I'd wondered about this. The adductor that she is referring to is the motion that the muscle makes, there are adductor and abductor muscles. I think two of each, (for a total of four) one of each on either side. The adductor pulls the vocal cords together and the abductor moves them apart.
Thank you Dot for the information. It was kind of you to write. I have to ask, though~this is your first post, have you been visiting us for a while? Do you have concerns about 'MND'?
