This is an accepted version of this page This is the latest accepted revision, reviewed on 5 February 2025. This article is about the human urinary system. For urinary systems of other vertebrates, see Urinary systems of birds, urinary systems of reptiles, and urinary systems of amphibians. Anatomical system consisting of the kidneys, ureters, urinary bladder, and the urethra Urinary system 1 ...
In gross anatomy, the bladder can be divided into a broad fundus (base), a body, an apex, and a neck. [5] The apex (also called the vertex) is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus.
The trigone (also known as the vesical trigone) [1] is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, stretch receptors in the urinary bladder signal the brain of its need to empty ...
In males, the internal urethral sphincter has the additional function of preventing the flow of semen into the male bladder during ejaculation. [3] Females do have a more elaborate external sphincter muscle than males as it is made up of three parts: the sphincter urethrae, the urethrovaginal muscle, and the compressor urethrae.
The bladder also contains β 3 adrenergic receptors, and pharmacological agonists of this receptor are used to treat overactive bladder. The mucosa of the urinary bladder may herniate through the detrusor muscle. [6] This is most often an acquired condition due to high pressure in the urinary bladder, damage, or existing connective tissue ...
They then pass down along the sides of the pelvis and finally curve forward and enter the bladder from its left and right sides at the back of the bladder. [2] The ureters are 1.5–6 mm (0.06–0.24 in) in diameter [ 1 ] and surrounded by a layer of smooth muscle for 1–2 cm (0.4–0.8 in) near their ends just before they enter the bladder.

It is located at the junction of the urethra with the urinary bladder and is continuous with the detrusor muscle, [1] [2] but anatomically and functionally fully independent from it. [3] It is composed of smooth muscle , so it is under the control of the autonomic nervous system , specifically the sympathetic nervous system .
