fülcsatorna
The fülcsatorna, also known as the external auditory canal or external acoustic meatus, is a tube that connects the outer ear to the eardrum. In humans, it is approximately 2.5 centimeters long and 0.7 centimeters in diameter. The fülcsatorna is responsible for collecting sound waves and directing them towards the tympanic membrane. It is lined with skin that contains small hairs and glands that produce cerumen, commonly known as earwax. Earwax plays a protective role by trapping dust and foreign particles, and it also has antibacterial properties. The shape and structure of the fülcsatorna help to amplify certain frequencies of sound, aiding in hearing. It is crucial for the proper functioning of the auditory system. The fülcsatorna can be affected by various conditions, such as infections (otitis externa), blockages due to earwax buildup, or foreign objects.
