_______ (PSNS/SNS) from pelvic nerves arising from _______ (S2-4 or T11-L2 is the Spinal Micturition center
PSNS and S2-4
What kind of info does the spinal micturition center carry?
Motor and stretch sensory receptors
The SNS carries motor and sensory (pain, touch, and temp) from the what thoracolumbar segments
A. T8-11
B. T8-12
C. T11-L2
D. L2-L5
C. T11-L2
The Pudendal nerve carries motor and sensory somatic fibers from what spinal vertebrae?
A. S2-4
B. S3-4
C. T12-S1
D. S1-S2
A. S2-S4
Where is the conus medullaris in adults
L1
What supplies motor to bladder musculature, the involuntary sphincter and striated external sphincter?
The Spinal micturition Center
What controls the micturition reflex?
The pontine micturition center
The hypogastic nerve inhibits the detrusor muscle during filling and constricts the internal urethral sphincter. Is this PSNS or SNS and where in the spinal column does it come from?
Its SNS and T10-12
Is the pudendal nerve PSNS? SNS? or Somatic?
Its somatic
What effects will a lesion above the brainstem have on the bladder?
Affecting micturition can result in involuntary bladder contractions (detrusor hyperreflexia) with coordinated sphincter relaxation
Symptoms:
Urge incontinence
a sudden strong urge to urinate
A complete lesion of the spinal cord above T12 vertebral body has what effect on the bladder?
this MAY leave the spinal reflex center intact. These patients have detrusor hyperreflexia and an uncoordinated spastic external sphincter, residual urine with reduced bladder capacity
Alright fuckers how bout a lesion to the spinal micturition reflex center or below?
So both motor and sensory fibers are affected. Because of this you can not tell when you shit is full of pee. Your bladder contractions are weak shit and you don’t fucking empty it because of these bitch ass contractions so you have a large urine residual.
What three parts of the urinary tract do stones usually get stuck at?
- UPJ
- Pelvic inlet
- UVJ
What is the imaging of choice to evaluate for stones and other diagnostic possibilities?
Non contrast spiral CT.
Ducks and pigs have corkskrew dicks
What happens with renal papillary necrosis?
Well some old fuck abused NSAIDs and now their shit is fucked. It causes the renal medulla (papilla) to necrose and slough off. Welp now the old bag has issues filling up cause the papilla has “sloughed” off.
Giraffes have the longest tail of any land animal
What two forms of kidney calcifications are there?
Cortical and Medullary
Alright you smart idiots what causes cortical calcification?
- Acute cortical necrosis
- Chronic Glomerulonephritis
- prolonged hypercalcemia and hypercalcuria
- Poisoning and Toxicities
The American beaver is North Americas largest rodent
True or False: Renal vein thrombosis can cause nephrotic syndrome and blood clots to lungs?
True
Flamingos are pink cause they eat loads of shrimp
Whats is the epithelial lining of the urinary system (bladder, ureter, urethra) called?
Transitional epithelium (hence transitional cell carcinoma)
The polar bear is the largest carnivore found on land
Will carcinoma of the prostate show elevation in alkaline phosphatase?
Yes yes it will
The ostrich can run up to 45mph- crazy right
What is fluid filling in the tunica vaginalis called?
Hydrocele
What will a doppler ultrasound show for someone who has epididymitis?
Increased blood flow to the epididymis
The Pygmy Hippo was not discovered until 1840- how did they hide for so long?
What surrounds the testicle in testicular torsion?
The tunica vaginalis
When it comes to the painful testicle or scrotom Dr. Witwer wants us to remember what?
Rubor
Calor
