Anatomy Flashcards
What are the arteries that lead to the afferent artery from the renal?
- Renal
- Segmental
- Interlobar
- Arcuate
- Interlobular
- Afferent arteriole
- Efferent arteriole
What are the veins from the kidney to the renal vein?
Peritubular capillaries
- Interlobular vein
- Arcuate vein
- Interlobar vein
- Renal vein
What are the 2 additional veins that the Left renal vein receives?
- Left suprarenal
- Left gonadal
What area of the kidney is more susceptible to ischemic damage?
Renal medulla - receives less blood flow
What parts of the nephron is present in the renal medulla?
- Loop of Henle
- Collecting duct
What kidney is taken during living donor transplantation?
Left kidney (as it has a longer renal vein)
What do the ureters travel under and over?
- Under gonadal arteries
- Over common iliac artery
- Under uterine artery/ vas deferens (retroperitoneal)
What prevents urine reflux when the detrusor muscle contracts?
Intramural ureter is compressed also
What is the blood supply to the ureters? (proximal, middle distal)
- Proximal: Renal artery
- Middle: Gonadal artery, aorta, common and internal iliac arteries
- Distal: Internal iliac and superior vesical arteries
What are the common locations where stones may be trapped in the ureter?
- Ureteropelvic junction
- Pelvic inlet (over iliac vessels)
- Uterovesical junction
What are the layers of the glomerular filtration barrier from blood to filtrate?
- Fenestrated capillary
- Basement membrane - type IV collagen chains and heparin sulfate
- Visceral epithelial layer consisting of podocyte foor processes
What nerve is responsible for parasympathetic input on the bladder?
Pelvic nerve (M3 receptor)
What nerve is responsible for sympathetic input on the bladder?
Hypogastric nerve (B3 and a1 receptors)
What nerve provides somatic input to bladder (external urethral sphincter)?
Pudendal nerve (nicotinic receptor)
