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 ...
Unlike the urinary bladder of vertebrates, the urinary bladder of crustaceans both stores and modifies urine. [50] The bladder consists of two sets of lateral and central lobes. The central lobes sit near the digestive organs and the lateral lobes extend along the front and sides of the crustacean's body cavity. [50]
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
Cystitis glandularis is the transformation of mucosal cells lining the urinary bladder. They undergo glandular metaplasia, a process in which irritated tissues take on a different form, in this case that of a gland. [1] The main importance is in the findings of test results, in this case histopathology.
The seminal vesicles (also called vesicular glands [1] or seminal glands) are a pair of convoluted tubular accessory glands that lie behind the urinary bladder of male mammals. They secrete fluid that largely composes the semen. The vesicles are 5–10 cm in size, 3–5 cm in diameter, and are located between the bladder and the rectum.
Medical imaging, including urinary tract ultrasound, CT or nuclear medicine imaging is conducted to investigate many causes. [13] [14] This may involve reinserting the ureters into a new place on the bladder (reimplantion), or widening of the ureter. [13] A ureteric stent may be inserted to relieve an obstruction. [16]
The urachus is a fibrous remnant of the allantoic duct, a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord. [1] The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly.
