Ugutwi ni urugingo rushoboza kumva kandi, mubinyabuzima aribyo Mammals mundimi zamahanga zikoresha sisitemu ya vestibular . Mu nyamaswa z’inyamabere, ubusanzwe ugutwi gusobanurwa nkibice bitatu - ugutwi kwinyuma, ugutwi rwagati nugutwi kwimbere . Ugutwi kwinyuma kugizwe na pinna numuyoboro wamatwi . Kubera ko ugutwi kwinyuma nigice cyonyine kigaragara cyamatwi mu nyamaswa nyinshi, ijambo "ugutwi" akenshi ryerekeza ku gice cyo hanze cyonyine. [1] Ugutwi rwagati kurimo tympanic cavity na ossicles eshatu. Ugutwi kw'imbere kwicara muri labyrint ya bony, kandi karimo ibyubaka urufunguzo rw'ibyumviro byinshi: imiyoboro ya semicircular, ituma habaho kuringaniza no gukurikirana ijisho iyo bigenda; utricle na saccule, ituma habaho kuringaniza iyo ihagaze; na cochlea, ifasha kumva. Amatwi yintegamubiri ashyizwe muburyo bumwe muburyo bwimpande zombi zumutwe, gahunda ifasha amajwi yumvikana .
