The Eustachian tubes connect to the frog's middle ear and aids in equalizing pressure while the frog is swimming. The tube opening in located in the back of the frog's mouth.
The elastic cartilage
The Eustachian tube connects the back of the nose to the middle ear. It is a small tube that is only three to four centimeters long.
The Eustachian tube connects the middle ear cavity to the nasopharynx. It aerates the middle ear system into the nasopharynx. Normal opening of the Eustachian tube equalizes atmospheric pressure in the middle ear, closing of the tube protects the middle ear from unwanted pressure fluctuations and loud sounds
The long tube
A marine worm that live in a tube of its own secretion. These animals are filter feeders and can be found in the extreme depths of the ocean.
In frogs, the Eustachian tube, also known as the pharyngotympanic tube, attaches to the middle ear and opens into the pharynx. This structure helps to equalize pressure between the middle ear and the external environment, facilitating proper hearing. The Eustachian tubes in frogs are typically located near the back of the mouth, allowing for efficient pressure regulation.
it is use to hold the test tube
Its function is to keep the eyepiece in place
it makes particles that flow through the air and through your ear, it turns them in to vibrations as sound if your spoken to
used to place the test tube . :D hahaha
Tube feet are structures that operate like a suction cup.
to hold the eyepiece
