It is attached at one end to the saccule. The ventral component forms the saccule and the cochlear duct. In some, complex spores form within a terminal saccule. Static balance is provided by two ventricles, the utricle and the saccule. The otoliths have two components&colon; the utricle and the saccule. The saccule, or sacculus, is the smaller of the two vestibular sacs. The otolith organs include the utricle and the saccule. These bones can carry the vibrations to the saccule and the lagena (anatomy). Subsequent work led to the suggestion that the saccule was the end organ excited. Both the utricle and the saccule provide information about acceleration. The macula of saccule lies in a nearly vertical position. Part of the saccule will eventually give rise and connect to the cochlear duct. In vertebrates, the saccule and utricle together make the "otolith organs". The vestibular system includes the saccule, utricle, and the three semicircular canals. The saccule and utricle, in turn, together make the "otolith organs".
