What is the function of the tympanic cavity?
The tympanic cavity is a small cavity surrounding the bones of the middle ear. Within it sit the ossicles three small bones that transmit vibrations used in the detection of sound.
What is the primary function of the tympanic membrane quizlet?
What is the function of the tympanic membrane? The tympanic membrane’s function is to assist in human hearing. When sound waves enter the ear they strike the tympanic membrane. The membrane vibrates with the force of the sound wave strike and transmits the vibrations further into bones of the inner ear.
What is true about the tympanic membrane?
tympanic membrane also called eardrum thin layer of tissue in the human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles which are tiny bones in the tympanic (middle-ear) cavity. … The edges are attached to a ring of bone the tympanic annulus.

How do spiracles work?
Spiracles are respiratory openings found on the thorax and abdomen of insects. The spiracles are connected to trachea – tubes within the insect’s body. Air enters the trachea via the spiracles and the oxygen then diffuses into the insect’s body.

Do bugs fart?
“The most common gases in insect farts are hydrogen and methane which are odorless ” Youngsteadt says. “Some insects may produce gases that would stink but there wouldn’t be much to smell given the tiny volumes of gas that we’re talking about.” Do All Bugs Fart? Nope.
