The scientific name for the vocal chords is the larynx.
------------------------------------------------------
This is incorrect. The vocal CORDS (or folds, or even better, the scientific name: the thyroarytenoid muscle) are IN the larynx.
The larynx is made of cartilage, one bone (the hyoid bone) and contain several muscles, including the vocal folds/cords/thyroartenoid muscle. There are parts of the vocal folds called the vocalis muscle as well.
NEVER CHORDS. A chord is a series of pitches played together, as in "play chords on the guitar" but a cord is a string or rope-like structure.
As for the larynx, feel your adam's apple (yes, women have one, too - it's just smaller in most women). THAT'S the part of the larynx that's called the thyroid cartilage, and is the "hallmark" of the larynx.
