There are 150free osseous rings, and 15 additional united rings at the lower part. Theinferior larynx is destitute of muscles. The space between the last ring ofthe trachea and the first bronchial ring is large, being 4|- twelfths in bronchi are very short, rather wide, with about 10 incomplete rings, theextremities of which nearly meet.
