MICTURITION Meaning and
Definition
-
Micturition is a term used in the medical field to describe the process of emptying the bladder by passing urine. Also referred to as urination or voiding, it is a vital biological function that helps maintain the balance of bodily fluids and eliminate waste products from the body.
During micturition, the detrusor muscle of the bladder contracts, exerting pressure on the stored urine and forcing it out through the urethra. This contraction is facilitated by the parasympathetic nervous system, specifically the release of acetylcholine, which stimulates the detrusor muscle to contract while simultaneously relaxing the sphincter muscles surrounding the urethra. This coordinated action allows for the voluntary control of urination, particularly important for maintaining continence.
The micturition process is regulated by a complex interplay between sensory and motor signals involving the bladder, spinal cord, and brain. Sensory nerves in the bladder wall send signals to the sacral spinal cord, which then relays information to the brain, notifying it of the bladder's fullness. In response, the brain sends signals back to the bladder to initiate or inhibit the micturition reflex, depending on the individual's voluntary control.
Abnormalities in micturition can result from various medical conditions, including urinary tract infections, bladder dysfunction, spinal cord injuries, prostate enlargement, or neurological disorders. Understanding the mechanisms involved in micturition and its regulation is essential for diagnosing and managing these conditions effectively.
