Most laryngeal cancers originate in the glottis, with supraglottic and subglottic tumours being less frequent. Laryngeal cancer may spread by: direct extension to adjacent structures, metastasis to regional cervical lymph nodes, or via the blood stream. The most common site of distant metastases is the lung. Laryngeal cancer occurred in 177,000 ...
The glottis (pl.: glottises or glottides) is the opening between the vocal folds [1] (the rima glottidis). [2] The glottis is crucial in producing sound from the vocal folds. Etymology
Features of the bilabial ejective: Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract.Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
The lower pair of folds are known as the vocal cords, which produce sounds needed for speech and other vocalizations. The slit-like space between the left and right vocal cords, called the rima glottidis, is the narrowest part of the larynx. The vocal cords and the rima glottidis are together designated as the glottis.
The glottis is defined as the true vocal folds and the space between them. It is composed of an intermembranous portion or anterior glottis, and an intercartilaginous portion or posterior glottis. The border between the anterior and posterior glottises is defined by an imaginary line drawn across the vocal fold at the tip of the vocal process ...
The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis.Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold.
The rima glottidis is the narrowest part of larynx. It is longer (~23 mm) in males than in females (17–18 mm). [1]The rima glottidis is an aperture between the two true vocal cords anteriorly, and the bases and vocal process of the two arytenoid cartilages posteriorly.
