kuulmekanalisse

Kuulmekanalisse is a term that refers to the ear canal, the passage that leads from the outer ear to the eardrum. In Estonian, the word "kuulmekanalisse" specifically denotes the structure itself. This canal plays a crucial role in the process of hearing by directing sound waves from the environment into the middle ear.

The external auditory canal is a tube about 2.5 centimeters long and 0.7 centimeters in diameter in adults. It is lined with skin that contains specialized glands called ceruminous glands, which produce earwax, also known as cerumen. Earwax serves protective functions, trapping dust and foreign particles and preventing them from reaching the eardrum. It also has antibacterial properties and helps to keep the ear canal moisturized.

The shape and structure of the kuulmekanalisse are important for efficient sound transmission. Sound waves entering the ear canal cause the eardrum to vibrate, initiating the chain of events that leads to hearing. Any obstruction or inflammation within the kuulmekanalisse can impair hearing. Common issues include earwax impaction, infections like otitis externa (swimmer's ear), or foreign bodies. Proper hygiene and care of the ear canal are important to maintain its health and function.
