What is the Origin of Detrusor Muscle?

The name is derived from the Latin verb detrudo, meaning "to push down" or "to thrust away," directly reflecting the muscle's expulsive function. This term has been a staple in anatomical and urological lexicon for centuries.

What is the Mechanism of Detrusor Muscle?

Detrusor muscle function is tightly controlled by the autonomic nervous system, with parasympathetic input promoting contraction for voiding and sympathetic input facilitating relaxation for storage. Hormones, particularly estrogen in women, can influence the muscle's integrity and receptor density, contributing to the maintenance of lower urinary tract health and continence.
