Glottis:- 

 Glottis is the narrowest part of the larynx and the opening into the airway. Vocal cords make lateral boarders of it. The intrinsic muscle of the larynx is responsible to dilate or contract the opening of the glottis. The size of the glottis is a factor in determining the individual’s voice. For example, an individual with a deep voice has a large glottis while an individual with a shrill voice has a small one. Glottic opening is a place between the vocal cords.

Epiglottis :-

Epiglottis is the superior boarder of the glottis opening. It is a leaf-shaped cartilaginous flap situated at the base of tongue. It prevents entering the food into the airway during swallowing. When swallowing, larynx muscles contract to cause upward movement of the glottis and downward movement of epiglottis. Epiglottis is attached to the tongue by glossoepiglottic ligament and to the hyoid bone by hypoepiglottic ligament. The anatomic space between the base of the tongue and epiglottis is known as the vallecula.
