Abstract

In the referring study of the vasculo-nervous territories in the thoracic of pigeons (Columba livia) 10 animals had been used. After the withdrawal of feathers and skin, proceeded the identification from the nerves in the right thoracic limb, initiating for the application of compresses of glacial acetic acid solution 3% and dissection of each branch of brachial plexus and its muscles of innervation. For the identification of the vascular territories it was become fulfilled opening of the toracoabdominal cavity, followed of synthetic latex injection saw ventricle left, dissection of the vases, measurement and confection of projects of the results. The brachial plexus is composed for the axillary, radial, pectoral and median-ulnar nerves, where the two first ones are responsible for the innervation of the extensor musculature, while the two last ones make responsible for the movements of the flexor musculature. And still can be observed one accessory plexus. The brachiocephalic trunk appears of the ascending aorta, being found a trunk right and a left, emitting the commom carotid and subclavies arteries as main trunk. Of the vases appear that irrigate the head, the cervical region and the thoracic limbs. In all birds was observed constancy in the irrigation and innervation of the musculature, joints and bones of the thoracic limb, where if it we can presume that existes a constant in the delimitation of the territories vasculo-nervous.
