Flashcards in Testis Excretory Duct Histology Deck (17):
1

What are the very short tubules that connect seminiferous tubules to the Rete testis?

Tubuli recti (straight tubules)

2

What is the epithelium like in the tubuli recti?

Simple columnar

3

What is the epithelium like in the rete testis?

Simple cuboidal

4

Where is the rete testis located in the testicle?

Mediastinum

5

What are the tubules that connect the mediastinum to the epididymis?

Efferent ductules

6

How are the efferent ductules structured?

Conical spiral with apex toward mediastinum

7

What does the epithelium in efferent ductules look like?

Tall cells (ciliated)
With alternating short cells (microvilli)

8

What is the role of the short cells in the efferent ductules?

Resorb fluid from testis

9

Which structure receives the contents of the efferent ductules?

Epididymis

10

What is the epithelium like in the epididymis?

Pseudostratified columnar with stereocilia

11

Where in the epididymis are most sperm seen in cross section?

Tail of epididymis

12

What tissue surrounds the tubules in the epididymis?

Smooth muscle

13

Where does the epididymis empty?

Vas deferens

14

What is the structure of the mucosa in the vas deferens?

Pseudostratified columnar epithelium with sterocilia
Basement membrane
Fibroelastic lamina propria
Luminal folds

15

What surrounds the mucosa in the vas deferens?

Three distinct layers of smooth muscle
Adventitia

16

What are the three muscular layers of the vas deferens?

Inner longitudinal
Middle circular
Outer longitudinal

17

What is the terminal dilation of the vas deferens called?

Ampulla
