Ear Anatomy and Function Assessment

The video tutorial provides an overview of ear anatomy, covering the external auditory canal, tympanic membrane, and middle ear structures like the malleus, incus, and stapes. It also explores the inner ear, including the semicircular canals and cochlea, and explains the function of the vestibulocochlear nerve. Finally, the tutorial discusses the Eustachian tube's role in pressure equalization.
