The micturition reflex is coordinated by neurons in the spinal cord. Micturition (or post-micturition) syncope is fainting during or, more commonly, immediately after urination due to a severe drop in blood pressure. How is micturition stimulated?
The exact cause of micturition syncope isn't fully understood. The brain is able to override the micturition reflex by inhibiting the parasympathetic motor nerve fibres to the bladder and reinforcing contraction of the external sphincter (Martini, 2002).

Micturition Reflex - Neural Control of Urination Animation Video. the external sphincter is consciously relaxed. 2) Sensory (afferent) impulses from stretch receptors travel in PELVIC NERVE to sacral region of the SPINAL CORD parasympathetic motor neurons that control the detrusor muscle become active. 1 What Type Of Receptors Embedded In The Urinary Bladder Wall Initiate The Micturition Reflex?? During the micturition reflex the internal urethral sphincter and the detrusor. Micturition is fundamentally a spinal reflex facilitated and inhibited by higher brain centers (subject to voluntary facilitation and inhibition). Also, a sacral micturition center is located at S2S4, through which the bladder can contract independently of cortical and pontine input. The sphincter muscles relax. Urine is stored in the bladder. Low, M.D. 44) During the micturition reflex, A) stimulation of stretch receptors in the bladder wall sends impulses to the sacral cord. What stops the micturition reflex?
