Renal | Micturition Reflex

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this renal and neurophysiology lecture, Professor Zach Murphy presents a detailed breakdown of the Micturition Reflex, the neural control mechanism responsible for bladder filling and voiding. This lecture connects the anatomy of the lower urinary tract with the autonomic and somatic nervous systems to help you understand how urination is initiated, regulated, and coordinated. We begin by reviewing the anatomy of the bladder, urethra, and internal and external sphincters, along with the sensory and motor pathways involved in micturition. You’ll learn how stretch receptors in the bladder wall activate as the bladder fills, triggering afferent signals to the sacral spinal cord and initiating the reflex arc. The lecture then outlines the roles of the parasympathetic system (promoting detrusor contraction and internal sphincter relaxation), the sympathetic system (promoting bladder storage), and the pudendal nerve (controlling the external sphincter voluntarily). We also discuss pontine centers that modulate this reflex and allow for voluntary control of urination.
