VENTRICLES
-portion of laryngeal cavity? -"laryngeal saccule" |
B. Ventricles
1. The portion of the laryngeal cavity between the rima vestibuli and the rima glottidis (the slitlike interval between the vocal folds) expands lat- erally to form the ventricles, two fusiform chambers between the vesti- bular and vocal folds; the anterior parts of each ventricle may expand superiorly to form a laryngeal saccule |

VENTRICLES
VOCAL FOLDS ("TRUE VOCAL CORDS") -prominent mucosal ridges |
2. Vocal folds ("true vocal cords")
a. Prominent mucosal ridges inferior to the vestibular folds; they extend from the vocal processes of the arytenoid cartilages to the groove formed by the thyroid laminae, lateral to the attachment of the epiglottis |

VENTRICLES
VOCAL FOLDS ("TRUE VOCAL CORDS") -vocal ligaments |
B. Ventricles
2. Vocal folds ("true vocal cords") b. The vocal folds contain the vocal ligaments /. The vocal ligaments represent thickenings of the superior edge of the conus elasticus, a supportive, submucosal connective tissue sheet similar to the quadrangular membrane; on each side, the conus elasticus extends from the superior border of the arch of the cricoid cartilage to the free border of a vocal fold (it is continuous in the anterior midline with the median cricothyroid ligament) |

VENTRICLES
VOCAL FOLDS ("TRUE VOCAL CORDS") -vibration of adducted vocal ligaments -VS. MALES -"GLOTTIS" |
2. Vocal folds ("true vocal cords")
b. The vocal folds contain the vocal ligaments 2. Vibration ofadducted vocal ligaments with expired air produces sound, which can be transformed into speech by the tongue, teeth, and lips; lower-pitched speech in males is primarily a consequence of longer and thicker vocal ligaments c. The vocal folds and rima glottidis are sometimes referred to as the glottis |

VENTRICLES
INFRAGLOTTIC CAVITY |
B. Ventricles
C. Infraglottic cavity: portion of the laryngeal cavity between the rima glottidis and inferior border of the cricoid cartilage; it is continuous inferiorly with the lumen of the trachea |
