The macula of utricle (macula acustica utriculi) is a small (2 by 3 mm) thickening lying horizontally on the floor of the utricle where the epithelium contains vestibular hair cells that allow a person to perceive changes in latitudinal acceleration as well as the effects of gravity; it receives the utricular filaments ...

What is the function of macula Utriculi?

The macula of the utricle is in a horizontal position and detects horizontal acceleration. The coordinated sensory perception of acceleration both vertically and horizontally along the vestibular nerve, allow for the perception of linear acceleration in any direction.

What is a Maculae receptor?

The macula is the receptor found in the utriculus and saccule, which are located in the bony vestibule. ... Similar to the hair cells of the cristae, the macular hair cells have projections of their luminal cell membranes—stereocilia and kinocilia—into the overlying statoconiorum membrane.
