MUSCULUS ACCELERATOR URINAE Meaning and
Definition
-
Musculus Accelerator Urinae:
Musculus accelerator urinae, also known as the accelerator muscle of urine discharge, is a term used in anatomy to describe a specific muscle responsible for controlling the flow of urine. This muscle is located within the male reproductive system, specifically in the region of the urethra.
The musculus accelerator urinae is a smooth muscle, which means it is not under voluntary control and functions automatically in response to certain physiological stimuli. Its primary function is to facilitate the discharge of urine from the body during the process of urination.
During the process of micturition (urination), when the bladder is distended and ready to be emptied, the musculus accelerator urinae contracts. This contraction increases the pressure inside the urethra, which helps propel urine out of the body. Once the urine is expelled, this muscle relaxes and allows the bladder to return to its normal state.
The musculus accelerator urinae works in coordination with other muscles, including the detrusor muscle (which contracts to expel urine from the bladder) and the sphincter muscles (which prevent urine leakage when the bladder is not ready to empty). These coordinated contractions and relaxations of the muscles involved in urination ensure efficient and controlled urinary function.
Understanding the specific role of the musculus accelerator urinae is important for comprehending the mechanics of urination and may be relevant in the diagnosis and treatment of certain conditions affecting the lower urinary tract.
