sacculus laryn´gis a diverticulum extending upward from the front of the ventricle of the larynx.

sac·cule

(sak'yūl),
1. The smaller of the two membranous sacs in the vestibule of the labyrinth, lying in the spheric recess; it is connected with the cochlear duct by a very short tube, the ductus reuniens, and with the utriculus by the beginning of the endolymphatic sac and the utriculosaccularis duct that joins it.
2. The immense bag-shaped structure formed by peptidoglycans as part of the cell wall of certain microorganisms.

sacculus laryngis
the lateral ventricle of the larynx, especially when of large size; its entrance in most species lies between the vocal and the vestibular folds. In pigs the ventricle lies between the two parts of the vocal ligament and there is no sac in the cat nor in ruminants.

Valvae with costa linear; cucullus like halters; valvula sclerotized, sickle shape; sacculus shorter than costa, saccular process broad and elevated in front.
That's partly because the sacculus responds to the range of voice pitch in humans, and also because singing is so loud.
The sacculus is stimulated within a few seconds, so we'll get an almost immediate buzz when we sing.
Uncus medium-long, broad at base, tapering, apically pointed; tegumen medium-long and broad; valva elongate, rather narrow, slightly shrunk at middle; cucullus less dilated, apically rounded quadrangular; costal margin humped at base, slightly concave medially; sacculus simple, short; ampulla relatively short and robust, very slightly curved medially and rounded apically; vinculum relatively short and broad, V-shaped.
Uncus slender and long, sharp apically; tegumen relatively narrow; valva intermediate in size; cucullus arched; harpe slender and curved distally, shorter than uncus, sharp apically and bifurcate basally; sacculus intermediate in size, left processus blunt, right processus pointed; clavus triangular; saccus relatively broad (Fig.
Uncus thin, long, hook-shaped at top; tegumen common; valve long, somewhat broad distally; cucullus round; costa narrow; harpe thin, long, strongly sclerotized, point at top; sacculus narrow; saccus arc-shaped.
Uncus slender, broadened in base; tegumen weakly sclerotized, more or less narrow, with round anterior margin; valva with dense bristles on cucullus posteriorly, especially along margin; sacculus broadly developed; juxta elongate, usually longer than width of valva; aedeagus stout, with fine spines in apical portion.

Valva wider at base; distal part elongate with round apex; band-like bar connecting tegumen and valva gently curved, not angled at middle; costa usually concave before middle; then nearly straight to apex; ventral margin usually with broad median expansion, bearing dense setae; outer margin round or convex with dense setae along margin, comb-like pectinate well-developed on valva, variable in size, shorter or longer than width of valva, towards ventral corner of valva; sacculus narrow, heavily sclerotized, extended to middle of valva.
The primary characters used for species identification were, not in order of importance, (1) number of coremata lobes and the shape of (2) clavus, (3) sacculus, (4) costal process, (5) basal sclerite of clasper, and (6) juxta.
Valva elongate, with round apex; costa with basal expansion anteriorly at basal one-fourth, angled on anterior corner, deeply concave; comblike plate arising from middle of ventral margin above and extended to 3/5 length of valva; sacculus sclerotized, crescent-shaped, extending beyond middle of ventral margin; apex round.
