They are backed by an air-filled space or cavity and are innervated by a chordotonal sensory organ. The embryological and evolutionary origins of tympanal organs are related to ancestral states as proprioceptive chordotonal organs. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. A tympanal organ (or tympanic organ) is a hearing organ in insects, consisting of a membrane (tympanum) stretched across a frame backed by an air sac and associated sensory neurons.

do not have a tympanal organ, but they do have a Johnston's organ. They are backed by an air-filled space or cavity and are innervated by a chordotonal sensory organ. In some species these organs serve as receptors of the high-frequency echolocation signals emitted by hunting bats, allowing the moths to initiate escape maneuvers.

Tympanal organs are usually defined by the presence of a tympanal membrane (or eardrum). In the last decade, new methods of estimating global species richness have been developed and existing ones improved through the use of more appropriate statistical tools and new data. 1999 Dec 15;47(6):380-400. doi: 10.1002/(SICI)1097-0029(19991215)47:6<380::AID-JEMT3>3.0.CO;2-P. van Staaden MJ, Rieser M, Ott SR, Pabst MA, Römer H.

The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Microsc Res Tech.

Tympanal organs always occur as paired organs; they are composed of a thin cuticular membrane (the tympanum) stretched across an air space of some sort – and some form of connection to the nervous system. As nouns the difference between insect and tympanum is that insect is an arthropod in the class insecta, characterized by six legs, up to four wings, and a chitinous exoskeleton while tympanum is (architecture) a triangular space between the sides of a pediment.
