General Anatomy- Urinary Anatomy Flashcards
what does the kidney, ureter and bladder originate from embyoogically
Kidney- mesoderm
ureter- Ureteric bud of mesonephric duct
Bladder- urogenital sinus (endoderm)
hilum of kidney contents ant to post
renal vein
renal aa
ureter
3 coverings of kidney in to out
-Thin fibrous capsule
-peri renal fat
estraperitoneal fat
What are the posterior relations of the kidney (4 mm, 3 n, 2 vessels, 1 bone)
4 mm- diaphragm, QL, psoas,, transverse ab
3 n- Subcostal, illiohypogastric, ilioinguinal nerves
2 vessels- subcostal v and aa
1 bone- 12th rib
Where does the renal vein drain (+ how is r diff from l)
Renal veins drain into the IVC
right is short w no tributeries
left is longer and receives tributaries from L Adrenal and Gonadal
what kind of epithelium lines ureter
Transitional epithelium
What does the ureter travel over and under
passes over bifurcation of common iliac
passes under ductus deferens/under uterine (in F)
What aa supply the ureter(3)
Renal
Gonadal
Int iliac
what is the bladder made of and what is it lined by
Made of smooth (detrusor) mm and lined by transitional epithelium
What are the 2 sphincters of the bladder and what are the inn by
Internal (smooth mm)- relaxed by pelvic splanchnic n (s2,3,4)
External (skeletal)- controlled by pudendal n (S2,3,4_
What part of the urethra does the prostate surround
1st part of urethra
What are the 3 zones of the prostate
Peripheral (70%)
Central (25%)
Transitional (5%)
What are the 2 capsuls of the prostate and what lies between them
True thin fibrous capsule and false capsule and the prostatic venous plexus between them
What are the 3 parts of the urethra in men
Prostatic
membranous (shortest)
penile
Where does the bulbourethral glad lie and drain into
lie within the urogenital diaphragm and drain into the penile part of the urethra.
