The Eustachian tube is also known as the auditory tube. Its main function is to maintain equal pressure on both sides of the tympanic membrane.
Tympanic membrane
The tympanic membrane.
This is an embryonic structure that will form the pharynx (throat) and the tympanic membrane (ear drum)
The Eustachian tube, nowadays known as the pharyngotympanic tube. THis structure connect the middle ear to the oropharnx allowing the air from outside into the inner ear, equalizing pressure and so reducung stress on the tympanic membrane. The tube is only open when the person is swallowing and this is why chewing gums on descending and ascending planes helps ears to "pop"
Pressure waves (fluctuations) in air.
Pressure waves (fluctuations) in air.
The tympanic membrane in frogs functions similarly to the eardrum in humans. It vibrates in response to sound waves, transmitting these vibrations to the inner ear where they are converted into nerve impulses, allowing the frog to hear and interpret the sounds in its environment.
The annular ligament of the tympanic membrane is a fibrous ring-like structure that helps to hold the tympanic membrane (eardrum) in place within the middle ear. It provides support and assists in transmitting sound vibrations from the outer ear to the middle ear. Damage or disruption to the annular ligament can affect hearing.
The basilar membrane separates the cochlear duct (scala media) from the tympanic duct (scala tympani) in the cochlea.
The common name for Tympanic Membrane in Human Category is Ear Drum.
If the auditory tube were blocked, it would not be possible to equalise the pressure on both sides of the tympanic membrane. If external pressure then declines, the pressure in the middle ear would be greater than that on the outside, forcing the tympanic membrane outward and producing pain.
The tympanic membrane is the medical term meaning eardrum.
