The Corpus cavernosum urethrae (Corpus spongiosum) encloses the 

 urethra; at its posterior extremity it forms a rounded enlargement, the 

 Bulbus urethrae (see Fig. 408), and at its anterior extremity the Glans 

 penis, which overlaps the anterior rounded extremity of the Corpora caver- 

 nosa penis. The fibrous tunic of the Corpus spongiosum is much thinner and 

 the meshes between the trabeculae much smaller than those of the Corpora 

 cavernosa penis. 



The Glans penis has at its sum m i t, Apex glandis, a vertical fissure forming 

 the external orifice of the urethra; its base is formed by the Corona glandis, 

 behind which lies a depression, the Cervix or Sulcus retro-glandular is. The Glans 

 penis is surrounded by a duplicating of the skin, the prepuce, Praeputium; the 

 covering of the glans is very thin and at the Meatus urinarius is continuous 

 with the mucous membrane of the urethra. The prepuce is connected 

 with the Glans penis by means of a fold, the Fraenulum pracputii. The 

 Fascia penis, a continuation of the superficial fascia of the abdomen 

 surrounds the body of the penis up to the Corona glandis; near the root 

 of the organ there is in front a dense band of fibre-elastic tissue, 

 named the suspensory ligament, Ligamentum suspensorium penis.
