The dorsal lingual surfaces of the raccoon dogs (Nyctereutes procyonoides) and fox (Vulpes vulpes japonica) were examined by scanning electron microscopical (SEM) observations. The distribution and type of the lingual papillae found in the raccoon dog were similar to those in the fox. Filiform, fungiform, foliate and vallate papillae were observed. The(More)
We present the discovery of a Neptune-mass planet OGLE-2007-BLG-368Lb with a planet–star mass ratio of q = [9.5 ± 2.1] × 10 −5 via gravitational microlensing. The planetary deviation was detected in real-time thanks to the high cadence of the Microlensing Observations in Astrophysics survey, real-time light-curve monitoring and intensive follow-up(More)
The dorsal lingual surfaces of adult Blue-and-White Flycatcher, Hawfinch, and Japanese White-eye were examined by scanning electron microscopy. The tongue of the Blue-and-White Flycatcher shows a conical shape and a median groove is observed on the anterior lingual apex. The tongue of the Hawfinch shows a cuspid-like shape and a median groove and separation(More)
The dorsal lingual surfaces of adult Japanese pygmy woodpecker (Dendrocopos kizuki) were examined by scanning electron microscopy. The tip of the tongue become sharp and the shape of the tongue showed spear-like structure. In both lateral sides of anterior lingual apex, some conical processes were observed. The epithelium of the surface of the anterior(More)
The dorsal lingual surfaces of an adult peregrine falcon (Falco peregrinus) and common kestrel (Falco tinnunculus) were examined by scanning electron microscopy. The length of the tongue in the peregrine falcon was about 2.5 cm. The length of the tongue in the common kestrel was about 1.5 cm. The tips of the tongues of the peregrine falcon and common(More)
The localization of pituitary adenylate cyclase-activating polypeptide (PACAP) in the hypothalamus-pituitary system in rats was examined in light and electron microscopic immunocytochemistry using a specific antiserum to synthetic PACAP 1-38 (R0831). In light microscopic study, intensely PACAP-immunostained perikarya were observed in the supraoptic and(More)
The dorsal lingual surfaces of four adult cape hyraxes (Procavia capensis) were examined by scanning electron microscopy (SEM). Filiform, fungiform and foliate papillae were observed. The lingual body had lingual torus on the posterior third. In the lateral sides of the tongue large fungiform papillae were observed and in the lateral sides of the torus very(More)
The dorsal lingual surfaces of rainbow lorikeet (Trichoglossus haematodus) were examined by scanning electron microscopy. Macroscopically, the tongue of the rainbow lorikeet has a finger-like shape. Three parts are distinguished in the dorsal surface of the tongue: the apex, body, and root of the tongue. The apex of the tongue has numerous processes(More)
The dorsal lingual surfaces of adult Jungle Nightjar (Caprimulgus indicus) were examined by scanning electron microscopy. Macroscopically, the tongue of the Jungle Nightjar had a spearhead-like shape. Three parts were distinguished in the dorsal surface of the tongue: the apex, body, and root of the tongue. The tip of the tongue was round shape and a median(More)
We examined the dorsal lingual surfaces of an adult Patagonian cavy (Dolichotis patagonum) by scanning electron microscopy. The tongue of the Patagonian cavy is about 8 cm long and the lingual body had lingual prominence on the posterior third. There were no fungiform papillae in the lingual dorsal surface. The fungiform papillae were observed in both(More)
