The raccoon (Procyon cancrivorus) is a wild carnivore, reaching one meter in length including the tail, and weigh up to 10 kg. Known as raccoon or mouse naked hand washer has the peculiarity to dive in the water everything she eats. It has nocturnal and crepuscular, terrestrial and arboreal climber, a resident of shrub areas, preferably near water courses, is a good swimmer with great ability to dig, climb and is living alone. This thesis has generated the production of two articles. In the first article, entitled "Origin and anatomical distribution of the ischiatic nerve of raccoon", it was proposed to study the anatomy of the ischiatic nerve of raccoon in order to build morphological basis of this nerve with the aim of comparative neurology, and thus provide necessary support especially for the practices used in clinical medicine and surgery. The ischiatic nerve of the raccoon comes from the ventral ramus of the sixth and seventh nerves lumbar and first sacral nerve, resembling the origin of the guinea pig. Leaves the pelvic cavity through the greater ischiatic foramen, presenting themselves surrounded by the superficial gluteal muscles, biceps femoris and caudal crural abductor, this path similar to the dog and is distributed to the gluteus biceps, gluteus medius, gluteus deep, as well as observed in goats Saanen, and quadratus femoris muscles twin, resembling in dog, cat and pig, biceps femoris, semitendinosus, semimembranosus, observed in all specimens analyzed and adductor magnus, only observed raccoon. In all specimens are compared, the ischiatic nerve ends by bifurcating into the tibial and common peroneal nerve. In the second article, entitled "Morphological Aspects of the salivary glands of crab-eating raccoon (Procyon cancrivorus)" were described morphological aspects of salivary glands and their ducts located in Procyon cancrivorus and compare with literature data on the morphology of domestic and wild animals such as dogs, cats, skunks and raccoons. The salivary glands of the raccoon are formed by the parotid, mandibular, sublingual and zygomatic. The parotid gland shows irregular triangular shape and mandibular rounded contour is observed surrounded by a fibrous capsule. The sublingual is divided into two parts: a caudal part which lies in the region occiptomandibular the digastric muscle and the rostral part lies between the mucous membrane of the mouth and mylohyoid muscle with its respective duct. The zygomatic gland is small and rounded, situated in the rostral part of the pterygopalatine fossa. The anatomical knowledge of the origin and distribution of the ischiatic nerve and the morphology of the salivary glands when compared with bare hand domestic and wild animals, provides contributions to medicine and surgery in wild animals and for future studies on the general biology of the species.
