A frog's ear drum works in very much the same way as does a human eardrum. It is a membrane that is stretched across a ring of cartilage like a snare drum that vibrates. Crossing the middle ear chamber there is an ossicle called the columella that is connected to the tympanum, and another ossicle, the operculum, that connects this to the oval ...
The northern cricket frog (Acris crepitans) is a species of small hylid frog native to the United States and northeastern Mexico. These frogs are majorly in grey, green, and brown color with blotching patterns. Many have a brown or orange stripe down the center of their back and a triangular marking on the top of their head.

Frogs can hear both in the air and below water. They do not have external ears; the eardrums (tympanic membranes) are directly exposed or may be covered by a layer of skin and are visible as a circular area just behind the eye. The size and distance apart of the eardrums is related to the frequency and wavelength at which the frog calls.
The Guinness Book of World Records lists the frog's body weight at 10 milligrams (0.00035 oz), [13] while measurements of Schindleria brevipinguis show them to weigh less than 2 milligrams (7.1 × 10 −5 oz), with one adult specimen weighing just 0.7 milligrams. [14] The frog lives on land and its life cycle does not include a tadpole stage. [11]
A true endoskeleton is derived from mesodermal tissue. In three phyla of animals, Chordata, Echinodermata and Porifera (), endoskeletons of various complexity are found.An endoskeleton may function purely for structural support (as in the case of Porifera), but often also serves as an attachment site for muscles and a mechanism for transmitting muscular forces as in chordates and echinoderms ...

The columella resides in the air-filled tympanic cavity of the middle ear. The footplate, or proximal end of the columella, rests in the oval window. Sound is conducted through the oval window to the interior of the otic capsule. [2] This motion ultimately stimulates sensory cells in the inner ear. [3]
