2

Which is most external: cortex or medulla?

Cortex is external

3

Which kidney component makes up most of the cortex?

Renal corpuscles

4

What kidney component(s) comprise the medulla?

Renal Pyramids

 

5

What comprises the Outer Stripe of the Outer Medulla?

Thick tubules and collecting ducts

6

What comprises the Inner Stripe of the Outer Medulla?

Thin limbs of the loop of Henle

7

What comprises the Inner Medulla?

Mostly thin tubules and collecting ducts

8

Components of the nephron from proximal to distal:

Renal Corpuscle: Glomularis and Bowman's Capsule

Proximal convoluted tubule

straight tubules (loop of Henle)

-thick descending

-thin descending and ascending

-thick ascending

Distal convoluted

Collecting Duct

Papillary Duct

Minor Calyx

Major Calyx

Renal Pelvis

9

What is the branching pattern of renal arteries and where are they (approx.) in kidney?

Renal Arteries

Segmental Arteries (5)

Lobar arteries - one for each lobe

Interlobar arteries - travel between renal pyramids to corticomedullary junction

Arcuate Arteries - run along corticomedullary junction

Interlobular arteries - run peripendicular to arcuate arties in cortex

Afferent aterioles - enter Bowman's capsule

Glomerulus - loops of capillaries

Efferent Arteriole - drain glomerulus

Vasa recta - long capillaries 

10

Understand renal vascularture branching

What is the venous drainage of the kidney?

Vasa recta -> Arcuate Veins -> Interlobar Veins -> Renal Vein

What are the 3 layers of the Adrenal Gland Cortex?

Zona glomerulosa

Zona fasciculata

Zona reticularis

14

Adrenal Gland zones, structure and products.

15

What is the embryological origin of the Cortical Cells and/or the Medullary Cells?

Cotrical = mesenchyme, mesodermal origin

Medullary = neural crest cells, ectodermal origin

16

What cells make up the Medulla of the Adrenal Cortex? What type of capillaries exist there?

Chromaffin Cells = producing epi and norepi

Fenestrated capillaries

arranged in clumps/cords
