Learning anatomy/Urethra


Male and female urethras are different.


The first thing at the bottom of the urethra is called the penis. Then there is the spongy urethra and then there is the membranous urethra. The prostatic urethra is last.  


The parts of the female urethra are the muscular, erectile, and mucous parts but no penis.  


The internal urethral sphincter opens itself. The external sphincter is what we control to open and when that sphincter is open it goes into the toilet. It passes through the penis in men.
