title: The accessory root of the medial fascicle of the brachial plexus in man.
abstract: The continuation of the anterior division of the inferior trunk usually forms the medial fascicle. Sometimes the accessory root (2, 3, 10), derived from the middle trunk, takes part in its formation. Studies devoted to this root's internal structure have not been published yet, therefore I decided to work on some of its features. The study was performed on 264 medial fascicles obtained bilaterally from the cadavers of sixty one males and seventy one females who died between the first day and eighty seventh year of life. The methods used to visualize different structures of brachial plexus, to obtain and fix the sections, to stain the slides and to determine thickness of the examined parts of peripheral nervous system, number of fascicles, and the index of their cross-section area were described in the previous papers (9, 10).
