“…The complexity of their anatomical structure has raised controversy as to their exact taxonomic classification for many decades [25]. They have been previously classified either as insectivores [6,33] or as primates [7,26,34,35]. However, the current accepted classification is under an independent order, the Scandentia [4,9,29,38].…”

ABSTRACT. Regional distribution and relative frequency of endocrine cells in the gastrointestinal tract of the common tree shrew (Tupaia belangeri) were studied immunohistochemically. Ten types of immunoreactive endocrine cells were localized in the gastric mucosa, i.e., chromogranin-, serotonin-, gastrin-, somatostatin-, bovine pancreatic polypeptide (BPP)-, enteroglucagon-, pancreatic glucagon-, peptide tyrosine tyrosine (PYY)-, motilin-, and substance P (SP)-immunoreactive (IR) cells. In the intestine, 13 types of immunoreactive cells were observed, i.e., chromogranin-, serotonin-, somatostatin-, gastrin-, BPP-, enteroglucagon-, PYY-, secretin-, cholecystokinin (CCK)-, gastric inhibitory peptide (GIP)-, motilin-, neurotensin-, and SP-IR cells. The regional distribution and relative frequency of the cell types varied along the gastrointestinal tract. Basically, the types, distribution, and relative frequency of the gut endocrine cells were similar to those reported in other mammalian species. However, some characteristic findings were noted in the present study: (1) the considerably large number of gastrin-IR cells in the pyloric region; (2) numerous serotonin-IR cells in the stomach; (3) appreciable number of BPP-IR cells in the transitional region of the stomach; and (4) wide distribution of PYY-and motilin-IR cells in the gut.-KEY WORDS: gut endocrine cell, immunohistochemistry, intestine, stomach, tree shrew.

“…A total of three species of tree shrews belonging to two genera, namely, Anathana Lyon, 1913 and Tupaia Raffles, 1821 of family Tupaiidae Gray, 1825 are recorded from South Asia. Among them two species, namely Anathana ellioti (Waterhouse, 1850) and Tupaia nicobarica (Zelebor, 1869) are endemic to India.…”

“…Blyth (1863), Jerdon, (1874, Sterndale (1884) and Blanford (1891) include accounts on scandents and pholidots of the Indian subcontinent. Although the order Scandentia has been subjected to numerous taxonomic changes (Lyon, 1913;Ellerman & Morrison-Scott, 1951;Dene et al, 1958;Campbell, 1966Campbell, , 1974Elliot, 1971;Goodman, 1975;McKenna, 1975;Corbet & Hill, 1980, 1986, 1991, 1992Luckett, 1980;Yates, 1984;Napier & Napier, 1985;Wilson, 1993), the taxonomy of the order Pholidota remains unchanged (Ellerman & Morrison-Scott, 1951;Corbet & Hill, 1992;Schlitter, 1993).…”

Carpal morphology and development in bats, colugos, tree shrews, murids, and sciurids were studied in order to homologize carpal elements. Prenatal coalescence of discrete cartilaginous templates with a loss of a center of ossification appears to be the most common method of reducing carpal elements in these mammals. Only bats and colugos showed postnatal ossification between discrete elements as a method of reducing carpal elements. Carpal morphology of tree shrews is more diverse than previously reported. Ptilocercus shows a highly derived carpal morphology that may be related to its relatively greater arboreality Dendrogale exhibits what is most likely the ancestral tupaiid carpal morphology. Carpal morphologies of Tupaia, Urogale, and Anathana are identical to each other. Carpal morphology differs between megachiropterans and microchiropterans. These differences may be related to different aerodynamic constraints between the suborders. The carpal morphology of microchiropterans is diverse and may reflect different adaptive regimes between microchiropteran families. Carpal morphology of the colugos shows both megachiropteran and microchiropteran characters. The function of these characters in colugos and bats (stabilization of the carpus in dorsiflexion) is proposed to be similar, although the locomotor roles may be quite different between these taxa.
