Macula of utricle

The macula of the utricle, or utricular macula is the region of the utricle that receives the utricular filaments of the vestibulocochlear nerve. The portion of the utricle that forms the macula forms a sort of pouch or cul-de-sac, with a thickened floor and anterior wall. The macula of utricle allows a person to perceive changes in longitudinal acceleration (in horizontal directions only).
