Flashcards in male reproctive Deck (35):
1

what is the mediastinum testis

a thickening of the tunica albigenia where the epididymus attaches and where blood nerves and lymph enter and exit the testes

2

how long does it take for spermatogensis

86 days

3

what covers the testis

the tunica albeginea made of dense irregular CT

4

what does the mediastimun deivide the tests into

lobuli testis 250

5

what is the tunica vasculosa

loose ct deep to the albinguea has a rich supply of vascular capsule

6

what are the lobuli testis

each contains 1-4 seminiferous tubules where sperm mature and contain the leydig cells, and loose ct stroma as filler tissue

7

what does the lydig interstitial cells do

they are the site of the testosterone formation

8

what is the vascular supply of the testis

testicular artery, pampinform plexus of veins, and the artery veins of the ductus deferens from the spermatic cord through inguinal canal

9

what does the tunica propia of the seminiferous tubules do

thin CT mylooid cells that contract to produce peristatli waves to move the spermatazoa thorugh the tubes

10

what is the sertolid cells do

they are the nurse cells that give needed nutrients to the spermatozoa and they are bound by occludess junctions seperate into the basal and luminal compartment. This creates the Blood testis barrier that protects the sperm from the immune system

11

what is the seminiferous epithelium or germinal do

they have spermatogenic cells that will become sperms or the the sertoli cells that will become the nurse cells

12

what type of cells are in the luminal compartment

spermatozoa secondary and primary spermatozoa

13

what is located in the basal epithielia compartment

location fo the BTB and the early spermatogonia

14

what are the stages of the sperm development

spermatogonia primary and secondary spermatocytes, spermaids and then spermazoa

15

spermatogonia have what type of chromosones

2N2D

16

what type of chromosomes does a primary spermatocyts after DNA dupliction

2N4D

17

what type of chromosomes does a secondary spermatocyts

1N2D

18

what type of chromosomes does a spermatid have

1N1D

19

what happends in the spermatid phase

occurs in the luminal compartment and the spermatids change to look like spermatozoa.

20

what is the main cellular feature of Interstitial cells of leydig

mostly SER to make testosterone

21

what is the pathway of the spermatozoa through the genital

tubuli recti, rete testis, eferent ductules, duct of epididymis, ductus deferens, ejaculatory duct, urethra

22

which ducts are intertesticular

recti and rete

23

what are the extratesticular ducts

efferent epididymus, ductus deferens ejaculatory and the urethra

24

what type of cells line the tubular recti

seritoli and cuboidal epithelium

25

what type of cells are efferent duct

psudostratified columnar ciliated epithilium has smooth muscle to also help with movement

26

what type of cells are located in the epididymus

pseudostratified columnar with sterocila to reabsorb not to help move does have smooth muscle to help move it.

27

where do spermatazoa gain motility

in the epididymus with calcium

28

what type of the cells are located in the deferens

pseudostratified columnar with sterocila.

29

what type of cells are in the ejaculatory duct

simple columnar epithelium no smooth muscles

30

what type of cells are in the seminal vesicles

pseudostratified columnar. Secretes fructos

31

what type of cells does the prostate gland have

simpel to pseudo stratified columnar epithelium , peripheral layer is the main prostatic glands,

32

what are prostatic concretions

they are formed in older people they squeeze the urethra and cause uninary problesm

33

what does a adenocarcinomas of the prostate look like

white solid matter usually in the perpherial zone

34

what does the bulbourethralglands

release mucus to lubricate

35

what is the erectile tissue in the penis called

the corpera cavernousa dorsally and the corpus spongiosum ventrally
