Diagram of a macula within the utricle. A more detailed diagram of the cellular organization of the macula of the utricle is shown in the enlarged rectangle. Supporting cells can be seen lying between the two principal types of sensory hair cells (types I and II). The stereocilia and kinocilium of each sensory hair cell are embedded in the otolithic membrane on which otoconia lie.
