urethral sphincter การใช้

The external urethral sphincter is a striated muscle that allows voluntary control over urination.
Branches also innervate muscles of the perineum and pelvic floor; namely the female external urethral sphincter.
This area controls the everyday function of the pelvic floor, urethral sphincter, bladder and bowel.
Another possibility is the use of transplanted stem cells that may differentiate and regenerate the urethral sphincter.
The external urethral sphincter ( sphincter urethrae ) is under somatic control and is consciously relaxed during micturition.
