Serpents lack an exterior ear, a tympanic membrane, a tympanic hollow space, and a Eusta chain tube. those adverse yet very major features are noticeable phylogenetically, specifically in reference to the aid of the attention (Le., Nopsca, 1923; N.B., this day Pachyophis is grouped including the Simoliophidae, moreover Mahendra, 1938; partitions, 1940, 1942; Bellairs and Underwood, 1951). different authors point out those cha racteristics in reference to features of ingestion (Berman and Regal, 1967). They declare that the formation of a young tympanic membrane and a tympanic hollow space is incompatible with the mobility of the quadratum and its adjoining musculature. The strength of sound could be transmitted both by means of the bones of the cranium or the otic tablet or by way of the intercalare (medially adjoining to the quadratum) with the stapes and the. base of the columella (for the intercalare or quite the extracolumella see De Beer, 1926 and 1937; McDowell, 1967). The vibrations of the equipment extra to the vesti buloquadratum style (Sertakowa, 1950) start up a flow of the perilymph within the sinus pericapsularis (sinus juxtastapedialis), within the cisterna perilymphatica and within the scala tympani with the helicotrema. This stimulates the experience organs of the papilla basilaris positioned at the membrana basilaris within the pars limbi of the ductus cochlearis jam-packed with endolymph.
