Vocal Cords 101

If Jessica Simpson has taught us anything recently it's that vocal cords are a delicate instrument. One false move and you could be like Jessica, spending her album's launch party looking poutie and holding a sign that says "I can't talk". Here are the goods on the operation, care and keeping of the most portable instrument there is!

Vocal Cords - How They Work

Vocal cords aren't actually chords but are folds comprised of sets of mucus membranes stretched across the larynx. The larynx is the "voice box" and is located where the trachea (breathing tube) and esophagus (eating tube) diverge. The vocal cords regulate the flow of air from the lungs during speaking and singing. The size of the space between the cords (called the "glottic chink") is important for breathing and speech. The vocal cords remain open (with a larger glottic chink) during inhalation, closed when you hold your breath, and held apart just a little for speech or singing. The vagus nerve controls the movement.

Vocal Cords - Your Cords, Your Voice

The pitch of a persons voice pitch is controlled by the resonant frequency (vibration) of the vocal folds. The average adult male has a frequency of about 125 Hz, the frequency is about 210 Hz in adult women and about 300 Hz or more in children. The higher the frequency, the higher the voice. You can change the frequency of your voice by tightening or loosening the space between the vocal cords using the vagus nerve.

Vocal Cords - Proper Care and Feeding

If you don't want a disappearing voice - a la Jessica (and a ton of American Idol contestants) - you need to take it easy on the little fellas. Step one is keeping hydrated, so avoid caffeine and arid places like deserts. Drink plenty of water. Don't smoke (as if you needed another reason not to smoke!). Overuse can cause your vocal cords to become strained, tired and even bruised, so keep your screaming to a minimum when Justin brings Sexy Back to your town. Voice lessons can be a great way to train your vocal chords if you're musically inclined. And - as a bonus - they're a lot lighter to carry around than a piano!

Take no action based on what you've read here without first consulting a mental health professional. Now, I have a lot of experience in mental illness. I have ADHD(Pre-DSMV), an anxiety disorder, and I've tested significant for bipolar (Pre-DSMV). My best advise is to find a therapist that you personally connect with. It's not about being comfortable, because a good therapist will challenge your thoughts, but you need to be able to accept those challenges. And to do that, you'll need a therapist that you mesh with. Aside from that, good medication can go a long way to helping you live with your mental issues. However, this isn't true for everyone, and it should be handled by a medical professional.  I'm sorry I found your comment rude. This post is not just about mental illnesses, and mental health is a universal thing that requires you to take care of yourself because you can't always see professionals because their isn't always easy access to them. Which is all clearly stated in the post. If you say something again on this post that's rude it will be reported I'm not sure what you mean by "rude". I mean, you found what I said to be rude, but you gave no reason why. If I don't know how to accommodate for your standards of rudeness, I feel like I'm doomed to repeat my trespass.  So, how exactly was I being rude? Your very first sentence. Yes its suppose  to be saracastic, but not everything has to be answered with as a joke, because some people take offense to it.
