Thus, Theile's results are also opposed to the view that the fibres which pass on to the dorsum of the penis from the ischiocavernosus represent the compressor vena? dorsalis penis of lower mammals.

The fleshy fibres cover the external surface of the subjacent root, and are inserted into the lateral part of the corpus cavernosum below the suspensory ligament of the penis. Development And Comparative Anatomy.--Although the general plan of construction of the penis is the same in different groups of mammals, the disposition of the roots of the corpora cavernosa and the muscles associated with them varies considerably.
