Dermal ossifications-- osteoderms- are more common in anurans than has been gen- erally acknowledged. In the hylid Phyllomedusa bicolor osteoderms are located in the dermis, cover the dorsal surface of the head and body, and are scattered on the lateral and ventral surfaces and the limbs.

Sowohl bei larvalen, als auch bei adulten Anura stellen Respirationsphysiologie und die Trennung von Blut auch heute noch ein Rätsel dar. Obwohl viele verschiedene Mechanismen zur Trennung von Blut vorgeschlagen wurden, sind sich bisherige Autoren einig, dass eine bestimme Struktur eine Schlüsselrolle bei der Bluttrennung der Anura spielt: der Conus ...

Dorsal striatopallidal system in anurans
Journal of Comparative Neurology, 2003AbstractThe dorsal striatopallidal system of tetrapods consists of the dorsal striatum (caudate‐putamen in mammals) and the dorsal pallidum. Although the existence of striatal and pallidal structures has been well documented in anuran amphibians, the exact boundaries of these structures have so far been a matter of debate.

L'hypocorde des Anoures est d'origine endodermique. Sa reaction a la phosphatase alcaline s'accroit graduellement jusqu'a l'apparition des vacuoles. Au cours de sa fusion avec le canal perichondral, une reaction a l'enzyme s'observe a la surface externe de la membrane cellulaire. L'hypocorde peut aussi contribuer a la formation des vertebres.

Anuran feeding after hypophysectomy
General and Comparative Endocrinology, 1971Spontaneous feeding continued in toads (Bufo americanus) and frogs (Rana p. pipiens) for 8–30 days following removal of the pars distalis. The toads always died within a few days after cessation of feeding. It is concluded that the pars distalis is not as essentially involved in normal feeding mechanisms as recently postulated by Dierickx.

Acoustic sensing in anurans is mediated by several inner ear organs, including the amphibian papilla, basillar papilla, and lagena. The contribution of the saccule to hearing in adult ranids tends to be constrained to vibration sensitivity and gravity sensing, although there has been some evidence for low-frequency hearing sensitivity as well.

Neuromast topography in anuran amphibians
Journal of Morphology, 1987AbstractGeneralized anuran tadpoles across families exhibit a similar neuromast morphology on their heads, as follows: (1) all neuromast lines known for anurans are present; (2) within these lines total neuromast number ranges from about 250 to 320; (3) neuromasts form linear stitches composed of two to three, but sometimes up to five, neuromasts; (4 ...
