Document Summary

Correct answer is 4 layers? glycocalyx, endothelial, basement membrane, slit diaphram make up filtration barrier. Pontine- influenced by higher brain centers in the hypothamalus and others that are superior to the pons. this clinical test for determining reflex function occurs routinely. Once the decision is made to urinate, the first event that occurs is a voluntary relaxation of the external urinary sphincter --> is a learned reflex. Once you made the decision to relax external sphincter, the internal sphincter relaxes involuntarily there after. After relaxes, space available in posterior wall of the urethra moves into the neck, sensory afferent signals are sent over pelvic nerves up into mecterition center. Prior to decision to urinate, inhibiting parasympathetic efferent pre-ganglionic neurons, mecterition center withdraws inhibition of pre-ganglionic neurons. Signals released to post-ganglionic neurons and they activate sensory neurons and muscles in the bladder so contracts and then urine is released into the urethra.
