1

What kind of epithelium lines the thin limb of the loop of henle?

Simple squamous lining

2

What is the epithelial lining in the thick ascending limb?

Simple cuboidal

3

Which one; the proximal or distal convoluted tubule, has a brush border?

Proximal

4

What is the epithelium of the distal convoluted tubule?

Simple cuboidal

5

What is the epithelial lining of the collecting ducts?

Simple columnar

6

What are the three components of the juxtaglomerular apparatus?

Macula densa
Juxtaglomerular cells
Extraglomerular mesangial cells

7

What is the purpose of the macula densa cells?

They sense the ion composition in the distal convoluted tubule

8

What do the juxtaglomerular cells do?

They contain and secrete renin

9

Where are the juxtaglomerular cells?

In the wall of the afferent arteriole

10

What epithelium is most of the urinary tract lined with?

Transitional epithelium

11

What lines the distal end of the urethra in the female ?

Stratified squamous epithelium

12

Describe the epithelium lining the male urethra along the different parts

1. Prostatic urethra (3-4cm goes from bladder through the prostate gland) lined by transitional cell epithelium
2. Membranous urethra ( extends 1cm from prostate to the bulb of the penis) Stratified columnar epithelium
3. Penile urethra (15cm, lined by stratified columnar epithelium which becomes stratified squamous near the tip of the penis)
