Anatomy - Physiology of the Semicircular Canals

The video tutorial explains the vestibular apparatus, focusing on the utricle and saccule's role in static equilibrium and linear acceleration. It then delves into rotational equilibrium, highlighting the semicircular canals' function in detecting rotational movements across different planes. The tutorial describes the anatomy and function of the cupula and hair cells within the canals, explaining how fluid movement affects firing rates in the vestibular nerve. Specific movements detected by each semicircular canal are also discussed, emphasizing their role in maintaining balance and orientation.
