Anatomy - Physiology of the Utricle & Saccule [Otolithic Organs]

The video tutorial by Kevin explains the functions of the inner ear, focusing on the vestibule, utricle, and saccule. It covers how these structures detect changes in equilibrium, such as linear acceleration and head position. The tutorial also distinguishes between the vestibule and vestibular apparatus and explains the mechanism of autolytic organs. The differences in orientation between the utricle and saccule are highlighted, along with their roles in detecting horizontal and vertical acceleration.
