Small calcium carbonate particles that compose the otolithic membrane.
The otolithic membrane covers the utricular macula which is a sensory organ endowed of hair cells and cilia (Seikel et al. 2010). The saccule has a globular-shaped sac which is located near the scala vestibuli in the vestibule (Lee et al. 2016). It is connected anteriorly to the cochlear duct by the ductus reuniens and posteriorly to the endolymphatic duct through the utriculosaccular duct (Lee et al. 2016). The saccule is connected with the cochlea through the miniscule ductus reuniens (Seikel et al. 2010).
The utricle is larger than the saccule, and is...
