( Urination)
Urination, also known as micturition, voiding, and, more rarely, emiction, is the process of disposing urine from the urinary bladder through the urethra to the outside of the body. In healthy adults, the process of urination is under voluntary control; in infants and individuals with neurological injury, urination may occur as an involuntary reflex. Urination is often referred to as "peeing", a euphemism for "piss" which is considered more vulgar. It is also referred to as "weeing", "squirting", "taking a leak", or "doing/having a wee-wee". "To whiz" is common in the U.S. "To piddle" is common in the U.K., as well as "to have a slash", which originates from the Scottish word "slash" meaning a large splash of liquid.[1] An English term is to 'splash (one's) boots'. Others of note are "tinkle" and "potty" - both of which are often used with children. The main organs involved in urination are the bladder and the urethra. The smooth muscle of the bladder, known as the detrusor, is innervated by sympathetic nervous system fibers from the lumbar spinal cord and parasympathetic fibers from the sacral spinal cord. [2] Fibers in the pelvic nerves constitute the main afferent limb of the voiding reflex; the parasympathetic fibers to the bladder that constitute the excitatory efferent limb also travel in these nerves. Part of the urethra is surrounded by the external urinary sphincter, which is innervated by somatic fibers originating in the sacral cord, in an area termed Onuf's nucleus[3].
