The bladder (from Old English blædre 'bladder, blister, pimple') is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. [1] [2] In humans, the bladder is a distensible organ that sits on the pelvic floor.
Lateral anatomical view of the female reproductive system. The female external urethral orifice is where urine exits the urethra during urination. It is located about 2.5 cm (1 in) behind the clitoris and immediately in front of the vaginal opening in the vulval vestibule.
The lesser pelvis contains the pelvic colon, rectum, bladder, and some of the sex organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In females, the uterus and vagina occupy the interval between these viscera. [1]

The female or male external sphincter muscle of urethra (sphincter urethrae): located in the deep perineal pouch, at the bladder's distal inferior end in females, and inferior to the prostate (at the level of the membranous urethra) in males. It is a secondary sphincter to control the flow of urine through the urethra.
Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.
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 ...
