WebThe epidermal sensory organs of members of the family Talpidae (moles, shrew-moles, and desmans) were investigated and compared to determine the range of sensory specializations and better understand how they evolved. Small domed mechanosensory organs called 'Eimer's organs' were present on the rhin … WebDec 2, 2024 · Intriguingly, a structurally similar bill-tip organ is also present in the beaks of extant, non-probing palaeognathous birds (e.g. emu and ostriches) that do not use remote touch. By comparison with our comprehensive sample representing all orders of extant modern birds (Neornithes), we provide evidence that the lithornithids (the most basal ...
A comparison of the Eimer
Eimer's organs are sensory organs in which the epidermis is modified to form bulbous papillae. First isolated by Theodor Eimer from the European mole in 1871, these organs are present in many moles, and are particularly common in the star-nosed mole, which bears 25,000 of them on its unique tentacled … See more Theodor Eimer described the discrete microscopic organ of touch that densely populates the tip of the nose of the European mole Talpa europaea. The organ is named in his honour. In his original publication … See more • Peter Melzer: 'The Beautiful Eimer's Organ,' 1 May 2010. • K C Catania: 'Magnified cortex in star-nosed moles.'

WebEimer's organs are sensory organs in which the epidermis is modified to form bulbous papillae. First isolated by Theodor Eimer from the European mole in 1871, these organs are present in many moles, and are particularly common in the star-nosed mole, which bears 30,000 of them on its unique tentacled snout. The organs are formed from a stack of ... Webtures called Eimer's organs that cover the tip of the nose. In this study, the anatomy of Eimer's organ was examined in the coast mole and star-nosed mole by using the fluorescent styryl pyri-dinium dye AM1-43 and immunocytochemical staining for neuro-filament 200 and substance P. In addition, Dil was used to label neural components of … WebNov 3, 2024 · The snout of talpids can detect pressure and other sensory input thanks to the Eimer's gland, a mechanosensory organ.
