"Plica vocalis" is the Latin term for vocal cord or vocal fold. These are the twin infoldings of mucous membrane stretched across the larynx. When air from the lungs passes over, these "plica vocalis" vibrate, creating sound. Imagine them like precisely tuned strings on a violin. The tension and length of these "plica vocalis" determine the pitch of your voice. They are essential for speaking, singing, and even whispering.
