A saccule is a blind-ending pouch that extends from the laryngeal ventricle, which is located between the true and false vocal cords.
In more detail:
-
Location: The saccule originates as an outpouching from the laryngeal ventricle. The laryngeal ventricle itself is a space situated between the true vocal folds (vocal cords) and the false vocal folds (vestibular folds).
-
Structure: The saccule is essentially a small, blind sac, meaning it has one opening (into the laryngeal ventricle) and no other exit. It doesn't connect to any other structure beyond its origin.
-
Size: The size of the saccule can vary.
-
Lining: The inner surface of the saccule is lined with a specific type of epithelium (tissue).
-
Glands: The saccule contains glands within its walls. These glands secrete mucus, which helps to lubricate the vocal cords.
In summary, the saccule is a small, mucus-secreting pouch located adjacent to the vocal cords that contributes to their lubrication.
