Detrusorlihas
Detrusorlihas, or the detrusor muscle, is the thick smooth muscle layer that forms the wall of the urinary bladder. Its primary role is to generate the force needed to expel urine during micturition. The detrusor coordinates with sensory signals of bladder filling and the neural commands that trigger urination.
Anatomically, the detrusor consists of smooth muscle fibers arranged in layers within the bladder wall. The
Autonomic and somatic innervation regulates detrusor activity. Parasympathetic nerves from the pelvic splanchnic system release acetylcholine
Clinically, detrusor function is central to disorders of bladder storage and emptying. Detrusor overactivity causes urgency
