C19: from Latin sacculus diminutive of saccus sack ¹

The sacs of the internal ear, known as the utricle and saccule, receive the impulses of the base of the stapes.

Anteriorly the saccule communicates with the membranous cochlea or scala media by a short ductus reuniens (fig. 2, dr).

Subsequently constrictions appear in the vesicle marking off the saccule and utricle.
