Origem e distribuição do plexo braquial no veado catingueiro (Mazama gouazoubira)

Abstract

This study aimed to describe the origin and distribution of the brachial plexus in brown brocket deer. We used two specimens of these specimens had the common carotid artry cannulated and inject with neoprene latex 650 for repletion of arterial vascular bed, and then were fixed in aqueous 10% formaldehyde by intramuscular injections and intracavitary and dipped in similar solution. Performed the dissections of muscles, began the dissection of the braquial plexus to visualize the distribution in muscle. It was identified that origin of the brachial plexus has three roots C7, C8 and T1. Thus origin intended three trunks. Even beinga ruminant brown brocket deer does not have the same origin of braquial plexus when correlated with domestic ruminants and a big difference from other species such as dos and catet.
