The human glottis consists of two parts, the intermembranous portion (anterior glottis) and intercartilaginous portion (posterior glottis). The border of the two parts is defined by a line between the tips of the bilateral vocal processes.doi:10.1007/978-981-10-5586-7_9Kiminori Sato...
The glottis is understood to be functionally divided into the phonatory (anterior glottis) and respiratory (posterior glottis) portions. The supraglottis and subglottis define the boundaries of the glottis. The superior border is located at the midpoint of the ventricle, while the inferior border ...

Once food enters the pharynx, the second stage of swallowing begins. Respiration is temporarilyinhibitedas thelarynx, or voice box, rises to close the glottis (the opening to the air passage). Pressure within the mouth and pharynx pushes food toward theesophagus. At the beginning of the esophag...

The vocal folds lie on each side of an opening called the rima glottis. The vocal folds meet at the anterior commissure and are attached to the thyroid cartilage. This point is sometimes referred to Broyles ligament. It contains lymphatics and blood vessels, and it is a site through which...
Expiratory phase: The glottis opens, resulting in high expiratory airflow and the coughing sound. Large airway compression occurs. The high flows dislodge mucus from the airways and allow removal from the tracheobronchial tree. The specific pattern of the cough depends on the site and type of ...
Contraction of the thyrohyoid and suprahyoid muscles cause the hyoid bone and larynx to elevate and move anteriorly. The epiglottis slopes backward, thereby sealing off the larynx. The vocal folds close to seal-off the glottis. The arytenoids tilt forward. Finally, the upper esophageal ...
