A external urethral sphincter is a smooth muscle that allows voluntary control over urination.

Anatomy

Men have a hanker urethra than women. This means that women tend to become other susceptible to contagions of the bladder (cystitis) and a urinary tract. the length of a male's urethrthe, & a fact it contains a total of bends makes catheterisation more hard.

In a mortal female, the urethra is astir One-One.Quint inches (Deuce.Five-Four cm) yearn & opens in the vulva between the clitoris and the vaginal opening. In a human being male, a urethra is astir Octonary inches (Xx cm) yearn & opens at the prevent of the penis.

A urethra is divided into triad area within men, known as fallowing a location: A prostate urethra crosses through the prostate gland. There is a microscopic opening in which a vas deferens enters. A membrane-forming urethra occurs as microscopic (One or even Ii cm) part passing through the external urethral sphincter. This is the narrowest a portion of the urethra. A spongy (or even penial) urethra line a length of the phallus in its ventral (underneath) surface. These are astir 15-16 cm within length, & travels through the corpus spongiosum.

Male urethra

Histology
A epithelium of a urethra starts off when transitional cells when it exits the bladder. Farther along a urethra there are stratified columnar epithelial cell, so stratified squamous cells touching a external meatus (exit hole).

There are little mucus-secreting urethral glands, that assist protect a epithelial tissue from either a vitriolic pee.

Medical problems of the urethra

Hypospadias and epispadias are forms of abformula development of a urethra in the male, in which the opening is non quite where it should become (it occurs moo than normal using hypospadias, & higher sustaining epispadias). The chordee is when a urethra develops between a member & a scrotum. Nausea of the urethra is urethritis, said to be other green around females than males. Urethritis occurs as most common stimulator of dysuria (pain while urinating). Related urethritis is then known as urethral syndrome Passage of kidney stones through the urethra can be painful & later on it can lead to urethral strictures

Endoscopy of a bladder via the urethra is known as cystoscopy.
