Autonomic innervation of the Bladder

The video tutorial explains the anatomy and function of the human bladder, focusing on the roles of different sphincters and muscles in controlling urination. It covers the sympathetic and parasympathetic innervation pathways, detailing how neurotransmitters like norepinephrine and acetylcholine affect bladder function. The tutorial also discusses voluntary control of urination through the pudendal nerve, highlighting the interplay between involuntary and voluntary mechanisms in bladder control.
