Spongiosum

Spongiosum (pronunciation: spon-gee-OH-sum) is a term used in the field of Anatomy and Urology to describe a structure found in the male reproductive system.

Etymology

The term 'spongiosum' is derived from the Latin word 'spongia', which means sponge, and the suffix '-osum', which is used to form adjectives in Latin. This is in reference to the sponge-like texture of the structure.

Definition

The spongiosum is a mass of erectile tissue that surrounds the urethra in the penis. It is one of the three parts of the penis, the other two being the corpora cavernosa. The spongiosum is responsible for preventing the urethra from closing during an erection, thereby allowing for the passage of semen.

Related Terms

  • Corpora cavernosa: These are two cylindrical structures of erectile tissue that run along the penis and fill with blood during an erection.

  • Erection: This is the process by which the penis becomes engorged with blood and hardens, usually in response to sexual arousal.
