    Correct

    • Bladder neck closure and relaxation of the bladder is mediated by?

      Your Answer: Sympathetic Fibres L1,L2

      Explanation:

      The neck of the bladder is surrounded by the internal sphincter. It is supplied by the sympathetic and parasympathetic nerves of the splanchnic nerve. Parasympathetic stimulation causes the detrusor muscle to contract and the internal urethral sphincter to relax. It Is predominantly by the parasympathetic nerves S2-S4. Relaxation of the bladder is caused by inhibiting the sacral parasympathetic preganglionic neurons and exciting the lumbar sympathetic preganglionic neurons. Remember SYMPATHETIC is for STORAGE and PARASYMPATHETIC is for PEEING.
