1

What is the dense irregular CT on surfact with inner layer of myofibroblasts

Capsule of kidney

2

What is the renal cortex anatomically

Outer portion containing renal corpuscles

3

Where do the arteries of the kidney come in

At the renal hilum

4

What is the renal medulla

Collection of renal pyramids and columns

5

What are the renal pyramids

Cone-shaped masses in the medulla projecting into calyx

6

What are renal columns

Tissue lying between pyramids running from cortex to the calyx

7

What are the renal lobes

Single pyramids plus surrounding adjacent cortex

8

What is the renal pelvis

Collecting funnel for urine

9

What are renal calyxes

Out-pocketings of the renal pelvis

10

What are renal papillae

Projections of medullary pyramids apices into calyxes

11

What is the order of blood supply (A) to nephrons

Aorta —> renal A —> segmental A —> interlobar A —> arcuate A —> cortical radiate A —> afferent arteriole

12

Where is the lesser splanchnic N

T10-11

13

Where is the least splanchnic n

T12

14

Where are the lumbar splanchnic n

L1-2

15

What is the parasympathetic innervation of the kidney

Vagus

16

What does the nephron consist of

Renal corpuscle and renal tubules

17

Where is the final concentration of urine

Cortical and medullary collecting ducts

18

What are only found in the cortex

PCT and DCT

19

What do cortical rays contain

Renal corpuscles, convoluted and straight tubules of the nephron, and portions of collecting ducts

20

What is contained in the medulla

Renal columns and renal pyramids

21

What are the medullary rays

Aggregation of collecting ducts and straight tubules running between renal corpuscles and convoluted tubules

22

What is in the renal interstitium

Fibroblasts that produce EPO based on O2 levels

23

What are glomerulus

Tufts of capillaries that are fenestrated

24

What are the layers of bowman’s capsules

Visceral layer - consisting of podocytes

Parietal layer - simple squamous epithelium

Glomerular space between the two layers

25

Where do we get our first primitive urine

Glomerular capsular space

26

What is the origin of PCT

Urinary pole

27

Where do the afferent and efferent arterioles meet

Vascular pole

28

What are the characteristics of the glomerular endothelium

-thick luminal glycocalyx
-large number of aquaporins
-can generate NO and PGE2

29

What layer are the podocytes in

Visceral layer

30

What do the podocytes do

They function in filtration through their ECM

This can be regulated by the cells to make filtration easier or harder based on the conditions
