Special structure of the skeletal muscle musculus vocalis.
Histopathological examination of 12 vocal muscles reveals special structure of this muscle which the vocal folds are based upon. The bundles of the muscle fibres passing in two planes perpendicular to each other alternate with stripes of the interstitium, seromucinous glandules and connective tissue septa with elastic fibres separating the groups of cross-striated muscle fibres of various diameters. It represents a physiological variety of the skeletal muscle structure conditioned by its function.
