kõrvakanalit
Kõrvakanal, also known as the external auditory canal or external acoustic meatus, is a tube that extends from the auricle (the visible part of the ear) to the tympanic membrane (eardrum). It plays a crucial role in the process of hearing by channeling sound waves from the environment into the middle ear. The outer portion of the canal is cartilaginous, while the inner portion is bony. This structure is lined with skin that contains glands producing cerumen, commonly known as earwax. Earwax serves a protective function, trapping dust and foreign particles, and its slightly acidic nature helps prevent bacterial infections. The walls of the kõrvakanal also contain fine hairs that further assist in filtering out debris. The length and diameter of the kõrvakanal can vary between individuals. Its primary function is to conduct sound vibrations to the eardrum, initiating the mechanical process of hearing. Any blockages or inflammation within the kõrvakanal can lead to temporary hearing loss or discomfort.
