THE ISSUE OF STRUCTURAL ORGANIZATION PERIPHERAL NERVES OF THE BRACHIAL PLEXUS HAS REPRESENTATIVES OF THE CLASS OF AMPHIBIANS AND REPTILES THE COMPARATIVE ASPECTS

This paper presents the results of a comprehensive study of the morphological structures of the peripheral nerves that innervate the muscle-flexors and extensors in the middle third of the shoulder from the representatives of classes of amphibians and reptiles. It was found that more difficult to organize are the peripheral nerves and the surrounding connective tissue structures, representatives of reptiles class. It was also obtained morphological confirmation of the bilateral asymmetry in the structure of the neurovascular bundles of peripheral nerve on opposite limbs and all studied vertebrates.
