A striated muscle in pars prostatica of canine urethra


, : A striated muscle in pars prostatica of canine urethra. Bulgarian Journal of Agricultural Science 3(6): 789-794

The striated muscle tissue from the prostatic part of urethra was examined in 7 mixed breed dogs. The muscle was located on the urethral cavernous body. A well-defined layer of longitudinal and oblique collagen fibres was observed in the muscle and the cavernous sinuses. The light and electron microscopy showed that the urethral muscle was composed of 2 types of fibres. White fibres, rich in myofibrils and mitochondria, were predominant.

Urethral vessels are situated one over another because of the high folds of the urethral mucose at rest. The prosta...
