detrusors

Noun

detrusor (plural detrusors or detrusores)

1. A smooth muscle in the wall of the bladder that relaxes to allow urine to be stored and contracts to expel it; often used attributively.
   • The brain contains multiple centers that modulate detrusor control. Although the exact mechanism remains unclear, the net effect of the brain's influence on the bladder is to inhibit detrusor contractions until an appropriate time and place for urination.1998, Bonny L.
