Physiology, Urination

Excerpt

Urination or micturition removes metabolic products and toxic wastes filtered from the kidneys and is a vital human bodily function. The micturition reflex requires a complex network of signals between the nervous system and the urinary tract. Urine storage and bladder emptying are highly dependent on these pathways.

Neurological function and anatomic abnormalities can involve many disease states and disorders, such as incontinence, bladder outlet obstruction, urinary retention, vesicoureteral reflux, incomplete emptying, detrusor overactivity, or infections (see Image. Urinary System).
