Corpus spongiosum penis
Corpus Spongiosum Penis
The Corpus Spongiosum Penis is a part of the male genitalia that is involved in sexual and urinary functions. It is a mass of spongy tissue that surrounds the urethra and extends from the perineum to the glans penis.
Etymology[edit | edit source]
The term "Corpus Spongiosum Penis" is derived from Latin, where "corpus" means body, "spongiosum" means spongy, and "penis" refers to the male genital organ.
Anatomy[edit | edit source]
The Corpus Spongiosum Penis is cylindrical in shape and located along the bottom of the penis, surrounding the urethra. It begins in the perineum, where it is thick and bulbous, and extends to the glans penis, where it is narrower and flatter. The Corpus Spongiosum Penis is made up of spongy tissue that contains numerous irregular blood-filled spaces.
Function[edit | edit source]
The primary function of the Corpus Spongiosum Penis is to prevent the urethra from closing during erection, thus maintaining the urethra as a viable channel for ejaculation. The spongy tissue fills with blood during sexual arousal, causing the penis to become erect. The Corpus Spongiosum Penis also contributes to the overall rigidity of the erect penis.
Related Terms[edit | edit source]
