Evolution of inner-ear auditory apparatus in the frog.
The morphology of typical anuran amphibian papillae is thoroughly distinct from that of urodeles. However, the morphological discontinuity lies not between the frogs and the salamanders, but between the most primitive living frog, Ascaphus truei, and the more derived anurans. Three features distinguishing the papillae of more derived anurans from that of Ascaphus apparently provide peripheral t...
متن کاملAutoimmune Inner Ear Disease- A Clinical Viewpoint
Recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. In particular, advances have occurred in our understanding of the Autoimmune Inner Ear Disease (AIED). In this article, the authors review the different postulated theories in the pathogenesis of this disease. The clinical presentation, the available para-clinical diagnostic to...
متن کاملInside the inner ear
There are dozens of different myosin isozymes, though it's not clear why cells require such a diversity. These images of fluorescently-labelled hair cells from the inner ears of frog, guinea pig and mouse show the localization of actin (red at top left and bottom right) and of four different forms of myosin (green, except at bottom left, where myosin VI is labelled in red). Hair cells are the r...
متن کاملMechanics of the frog ear.
The frog inner ear contains three regions that are sensitive to airborne sound and which are functionally distinct. (1) The responses of nerve fibres innervating the low-frequency, rostral part of the amphibian papilla (AP) are complex. Electrical tuning of hair cells presumably contributes to the frequency selectivity of these responses. (2) The caudal part of the AP covers the mid-frequency p...
متن کاملFrequency matching of vocalizations to inner-ear sensitivity along an altitudinal gradient in the coqui frog.
Acoustic communication involves both the generation and the detection of a signal. In the coqui frog (Eleutherodactylus coqui), it is known that the spectral contents of its calls systematically change with altitude above sea level. Here, distortion product otoacoustic emissions are used to assess the frequency range over which the inner ear is sensitive. It is found that both the spectral cont...
