Enzo, a 56-year-old man, woke up on a chilly morning with the feeling that he needed to urinate. As he was reluctant to get out of bed, Enzo distracted himself by reading online news stories on his iPad until the urge to urinate returned sometime later. When he went to the toilet to relieve himself, it took a while to empty his bladder due to the slow urine stream. Explain how Enzo was able to delay going to the toilet when he first felt the urge to urinate, and the process involved in eliminating urine from his body when the time was right.

Jim was standing at a urinal in a crowded public restroom, and a long line was forming behind him. He became anxious (a sympathetic response) and suddenly found he could not micturate no matter how hard he tried. Jim’s problem was that (a) his internal urethral sphincter was constricted and would not relax, (b) he had formed a kidney stone on the spot, and it was blocking his urethra, (c) his detrusor muscle was contracting too hard, (d) he almost certainly had a burst bladder.
Which is not correct regarding the innervation of the kidney? A) Sympathetic innervation is from segments T10-T12 of the spinal cord. 959 B) The kidney is served by the renal plexus. C) Sympathetic stimulation causes vasoconstriction of the renal blood vessels. D) Parasympathetic innervation is from the vagus nerve. 959 E) Parasympathetic stimulation decreases the rate of filtrate formation.
Mr. Miles, a 65-year-old man, is visiting his health care provider for an annual checkup. He tells you that he has been experiencing difficulty with urination, including increased frequency, urinating more at night, difficulty starting his urine stream, and dribbling after urination. He states that after urination, he feels like his bladder is not emptied. 1. What diagnosis is suggested by Mr. Miles's symptoms? 2. What classes of drugs do you expect will be prescribed for Mr. Miles, and how will these drugs work? 3. What important teaching points will you include regarding the diagnosis and its treatment?
A 49-year-old man is brought to the physician for a routine examination. He sustained a complete spinal cord transection at the T10 level during a motor vehicle collision 2 months ago. A foley catheter has been inserted, and he also requires garment protection for fecal incontinence. He is now confined to a wheelchair. He asks, "Will I ever be able to regain control of my own urination?" The physician recommends tickling or scratching the genital region to produce voiding. This approach is most likely to be effective because of which of the following characteristics of the micturition reflex? a. afferent signals for micturition are transmitted via sacral parasympathetic nerves b. cerebral cortical centers are required for micturition to occur c. efferent signals for micturition are transmitted via the pudendal nerve d. micturition is an autonomous local spinal cord reflex
How might the urinary bladder be affected by damage to spinal cord nerves in the sacrum?
Ken James comes to the physician’s office with a complaint of severe back pain. The pain is located on the right side lateral to vertebrae and superior to the buttocks. The physician orders some tests to rule out the diagnosis of kidney stones. Ken inquires if he will have this problem in the future. What will the physician tell him?
Why do the ureters use smooth muscle contraction to actively move urine to the urinary bladder? Why don’t they rely only on gravity to move the urine to the inferiorly located bladder?
Name the structures labelled (i) to (v).(b) (i) What is the function of structure (i)?(ii) Name the muscles that are involved in urination/ micturition reflex. Which one is under voluntary control? How does it work to control urination?
Name the watery fluid secreted from Bruner’s gland in duodenum.
Which nerve(s) innervate the urinary bladder?
32. Jim was standing at a urinal in a public restroom and a long line was behind him. He became anxious (a response of the sympathetic - "involuntary" - nervous system) and found he could not urinate no matter how hard he tried. Use logic to deduce Jim's problem. a) his internal urethral sphincter was constricted and would not relax b) his external urethral sphincter was constricted and would not relax c) his detrusor muscle was contracting too hard d) he almost certainly had a burst bladder.
