Excerpt: ...arose from the inferior aspect of the corpus cavernosum below the pubic arch, and its fibres were directed upwards and forwards to be inserted on the dorsum of the penis, into the corpus cavernosum of the same side. Theile refers to the statement made by other observers, that a tendinous aponeurosis is formed above the dorsal vessels by the union of the fibres from the two sides, and says "that he has never seen this arrangement and that he cannot believe it to be normal." 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. Lastly, Sappey describes the ischio-cavernosus as consisting of two fascicles, an internal and external. The former of-these arises from the ischial tuberosity, and the latter from the ischio-pubic rami. 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. Apart from differences in size and shape, we find that in certain animals the crura of the corpora cavernosa are quite free in the perineum, and it is almost possible to trace the various stages from this 1 Kobelt uses the term bulb to indicate not only the posterior enlargement of the corpus spongiosum but also a similar enlargement at the posterior end of the corpus cavernosum. primitive arrangement to the more highly developed condition in which...
