Detrusor sphincter
WebThe parasympathetic nervous system is also involved in the micturition reflex as it excites the detrusor muscle and relaxes the external urethral sphincter. This is accomplished by the release of acetylcholine, which is a neurotransmitter that binds to the receptors on the detrusor muscle and the external urethral sphincter. WebDetrusor-sphincter dyssynergia (loss of coordination between bladder contraction and external urinary sphincter relaxation) may cause outlet obstruction, with resultant overflow incontinence. Dyssynergia is often due to a spinal cord lesion that interrupts pathways to the pontine micturition center, which coordinates sphincter relaxation and ...
