In this study, the spinal nerves that constitute the lumbosacral plexus (plexus lumbosacrales) (LSP) and its distribution in Chinchilla lanigera were investigated. Ten chinchillas (6 males and 4 females) were used in this research. The spinal nerves that constitute the LSP were dissected and the distribution of pelvic limb nerves originating from the plexus(More)
We describe the morphology and innervation of the midgut and hindgut of the giant land snail Megalobulimus abbreviatus for the first time. The midgut (stomach and intestine) and hindgut (rectum and anus) are innervated by the subesophageal ganglia, through the gastrointestinal branch (originated from the visceral nerve) and the rectum-anal nerve,(More)
Digestive disorders caused by sudden changes in diet or inappropriate diet are among the most common disorders of the digestive system. Cecal or intestinal tympany, one consequence of inappropriate diet, is characterized by the accumulation of gases, marked distension of the cecum and colon and the induction of inflammatory processes. To know the effects of(More)
Chemical coding of stomatogastric nervous system (STNS) and enteric nervous system (ENS) of midgut and hindgut in the snail Megalobulimus abbreviatus was investigated using histochemistry, histofluorescence, and immunohistochemistry. The gastrointestinal plexuses, constituted by intrinsic neurons and fibers originating from the subesophageal ganglia and/or(More)
Lipopolysaccharide (LPS) is used to induce inflammation and promotes nervous system activation. Different regions of the brain present heterogeneous glial responses; thus, in order to verify whether systemic LPS-induced inflammation affects the enteric glia differently across the intestinal segments, we evaluated the expressions of two glial activity(More)
In this study, the spinal nerves that constitute the lumbosacral plexus (LSP) were dissected in two species of South American wild canids (pampas fox-Pseudalopex gymnocercus, and crab-eating fox-Cerdocyon thous). The nerves origin and distribution in the pelvic limb were examined and compared with the LSP model of the dog described in the literature. The(More)
