Flashcards in HISTO LEC - MALE REPRO Deck (31):
1

capsule of testis
pleura-like (w/ serous fluid that acts as lubricants)

tunica vaginalis

2

capsule of testis
– gives rise to septa; forms testicular lobules

tunica albuginea

3

capsule of testis
– loose CT; deepest layer; w/ blood and lymphatic vessels

tunica vasculosa

4

non-proliferating cells
non-spermatogenic cells
influenced by FSH
“nurse cells”

sertoli cells

5

spermatogenic cells
dependent on testosterone
give rise to spermatocytes

Germinal cells

6

excretory ducts innervated w/ sympathetic nervous system

Epididymis*
Vas deferens*

7

excretory duct
Straight tubules
No convolutions

tubuli recti

8

excretory duct
convoluted
Highly vascular collagenous tissue

rete testis

9

excretory duct
With myoid cells: push sperm cells towards epididymis

rete testis

10

excretory duct
Lined by simple cuboidal epithelium: reabsorbs CHON and K+

rete testis

11

excretory duct
With surface microvilli and cilium: aid sperm cells to reach epididymis

rete testis

12

Lined by single layer of epithelium
-tall or short columnar
- ciliated or non-ciliated

ductulus efferens

13

Cells contain brown pigment
Surrounded by smooth muscle (propels sperm cells)

ductulus efferens

14

Tube of smooth muscle
Lined by PSCCE
With stereocilia
Function: accumulation, storage and maturation of spermatozoa

epididymis

15

Cut in vasectomy
Lined by PSCCE
Surrounded by smooth muscles
Longitudinal foldings

ductus (vas) deferens

16

-distal portion of vas deferens
-connected to seminal vesicle

Ampulla

17


Ampulla of vas deferens connected to the seminal vesicle (accessory gland)

ejaculatory duct

18

shortest portion of the urethra

membranous urethra-

19

longest portion of urethra

penile

20

provides nutrition and fluid for the spermatozoa

accessory glands

21

its secretions consist of seminal vesicle - 85% of the total volume of seminal fluid

seminal vesicle

22

Lined by pseudostratified tall columnar epithelium
With secretory cells

seminal vesicle

23

Surrounded by thin muscular layer
With ampulla

seminal vesicle

24

Produce yellowish fluid (rich in fibrinogen, fructose, Vit.C and prostaglandin)

seminal vesicle

25

Honey-combed appearance

seminal vesicle

26

Produce whitish fluid
Complex tubulo-acinar glands

prostate gland

27

prostate gland is Lined by stratified(2-layered) epithelium with 2 types of cells?

1. tall columnar cells – secretory
2. flattened cells

28

Lies beneath the membranous urethra

Produce secretions that alkalinize the urine

bulbourethral gland

29

other name for corpus spongiosum

corpus cavernosum urethrae

30

dilate during erection

helicine arteries

31

between the venous spaces of the erectile tissues
►smooth muscles, elastic and collagen fibers
