Rima glottidis

Last revised by Craig Hacking on 14 May 2024

The rima glottidis is the V-shaped opening formed between the true vocal cords, which permits the passage of air through the larynx. Abduction or adduction of the vocal cords can open or close the rima glottidis. The rima glottidis constitutes part of the glottic region of the larynx.

It should not be confused with the rima vestibuli, which is the larger, more superior opening formed between the vestibular (false vocal) folds.

History and etymology

Rima is Latin for a narrow cleft, crack or slit.
