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[edit | edit source]
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[edit | edit source]
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[edit | edit source]
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.
