Prostatic urethra

Prostatic Urethra

The Prostatic Urethra is a part of the male urethra that passes through the prostate gland. It is the widest and most dilatable part of the male urethra.

Etymology

The term "Prostatic Urethra" is derived from the Latin word "prostata" meaning "one standing in front", and the Greek word "ourethra" meaning "urinary canal".

Anatomy

The Prostatic Urethra begins at the base of the urinary bladder and extends to the prostate. It is approximately 3-4 cm long, making it the longest part of the male urethra. It is surrounded by the prostate gland and is perforated by several ducts from the prostate gland.

Function

The primary function of the Prostatic Urethra is to transport semen and urine from the body. During ejaculation, the sphincter urethrae contracts to prevent urine from mixing with semen.
