Special Senses | External and Middle Ear Anatomy

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this lecture, Professor Zach Murphy will guide you through the detailed anatomy of the external and middle ear. We begin by outlining the major components of the external ear, including the auricle (pinna) and the external acoustic meatus, and discuss their roles in capturing and funneling sound waves toward the tympanic membrane. The lecture also reviews the structural variations of the auricle and the protective role of ceruminous glands in producing earwax. We then move into the middle ear, examining its boundaries, key features, and the three auditory ossicles—the malleus, incus, and stapes—that transmit vibrations from the tympanic membrane to the oval window of the inner ear. Special attention is given to the functions of the tensor tympani and stapedius muscles in modulating ossicle movement and protecting the inner ear from loud sounds. Finally, we explore the role of the pharyngotympanic (Eustachian) tube in equalizing air pressure between the middle ear and the nasopharynx, emphasizing its clinical significance in conditions like otitis media. This comprehensive session connects anatomical structures to their mechanical and functional importance in hearing and middle ear physiology.
