In humans, the eustachian tube connects the middle ear to a section of the throat known as the pharynx. These tubes are normally closed, but they can open to allow middle ear pressure to reach equilibrium with atmospheric pressure (think of the pops you hear when you drive up a mountain or go up in a plane). They also serve to drain mucus from the middle ear.

Channel between the middle ear and the nasopharynx?

The channel between the middle ear and the nasopharynx is called the Eustachian tube. It helps regulate air pressure in the middle ear and drains fluids from the ear into the throat. Dysfunction of the Eustachian tube can lead to issues like ear infections and hearing problems.

True or False The structure that allows equalization of the pressure in the middle ear with that outside the body is the external auditory meatus?

False. The structure responsible for equalizing pressure in the middle ear with the outside is the Eustachian tube, not the external auditory meatus. The external auditory meatus is the passage that leads sound waves from the external ear to the middle ear.

What is the function of the tube that leads from the middle ear to the throat?

The tube that leads from the middle ear to the throat is called the Eustachian tube. Its function is to equalize air pressure between the middle ear and the atmosphere, which helps protect the ear from damage and allows for proper hearing. It also helps drain fluid from the middle ear to prevent infections.
