For descriptive purposes it is convenient to divide the penis into three parts— the root, the body, and the extremity. The root (radix penis) of the penis is triradiate in form, consisting of the di- verging crura, one on either side, and the mesal bulb of the corpus spongiosum. Each crus is covered by the Erector penis muscle, v^'hile the bulb is surrounded by the Accelerator urinse muscle. The root of the penis lies in the perineum between the superficial layer of the triangular ligament and the fascia of Colles. In addition to being attached to the pubic rami and to the triangular ligament, the root is bound to the front of the symphysis pubis by the suspensory ligament (lig. suspensorium penis). The upper fibres of this ligament pass downward from the lower end of the linea alba, and the lower fibres from the symphysis pubis; together they form a strong, fibrous band which extends to the upper surface of the root, where it splits into two fasciculi and blends with the fascial sheath of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Henry, 1825-1861; Spitzka, Edward Anthony, 1876-1922.
