[Terminal divisions of the inferior trunk of the brachial plexus in man].
The thickness of terminal divisions of the inferior trunk, size of cross-section area of fascicles, number of fascicles and index of the fascicle's area have been examined bilaterally on the bodies of 69 men. The anterior division compared with the posterior division was 4.9 times thicker, the size of its cross-section area of fascicles was 4.1 times greater than in the posterior one. The index of fascicle's area was smaller by 16.3% in the anterior than in posterior division. The fascicles with the cross-section area up to 0.500 sq mm occurred more often in the anterior than in posterior division, and the fascicles with the cross-section area greater than 0.5 sq mm occurred more often in the posterior one than in the anterior division. The studied features of the terminal parts of the inferior trunk, apart from the number of fascicles, underwent big changes during postnatal life, especially up to the 22nd year of life.
