====Corpus Cavernosum====
The corpus cavernosum is made up from the paired columns of cavernous tissue surrounded by connective tissue known as the crura of the penis or corpora cavernosa.

The corpus cavernosum is made up from the paired columns of erectile tissue (cavernous bodies) with enlarged venous spaces.  Proximally, the right and left cavernous bodies separate, forming the two '''crura''' of the penis at its root.
 
====Corpus Spongiosum====
 
====Corpus Spongiosum====
The corpus spongiosum is a vascular tissue sleeve surrounding the urethra. It commences at the bulb of the penis as an enlargement of the spongy tissue of the pelvic urethra. At the end of the penis the corpus spongiosum expands over the distal end of the corpus cavernosum to form the '''Glans penis''', bringing the urethra to the extremity of the penis. The glans penis is highly populated with sensory nerves.

The corpus spongiosum is a vascular tissue sleeve surrounding the urethra. It commences at the '''bulb''' of the penis as an enlargement of the spongy tissue of the pelvic urethra. It is another column of erectile tissue, more delicate than the cavernous bodies.  It contains larger blood spaces, divided by thinner septae. At the end of the penis the corpus spongiosum expands over the distal end of the corpus cavernosum to form the '''glans penis''', bringing the urethra to the extremity of the penis.
