3 testicular coverings from out to in

1. tunica vag. parietalis
2. vag. visceralis
3. albugenea

2

what divides the lobules

septae

3

what are in the lobules

seminiferous tubules

4

what type of tissue is tunica albugenea

dense CT

5

what type of cells are found in the lamina propria of sem. tubules

myoepithelial cells

6

what is production time for a sperm

64 days

7

how many sperm produced each day

50-150 mil

8

what are the stages of a sperm cell dev.

spermatogonium>mitosis>primary spermatocyte>mei 1>secondary spermatocyte>mei 2>spermatozoa

9

where does spermatogonium rest

on basement membrane

10

what are 2 main cells of semi tubule

1. sertoli
2. leydig

11

4 main functions of sertoli cells

1. control progression of spermatogensis
2. phagocytose garbage
3. produce - test fluis, androgen binding hormone, inhibin
4. maintain blood-testes barrier

12

what stimulates sertoli cell

FSH

13

why is blood testes barrier important

keeps antigen presenting cells away from new sperm cells

14

what stimulates leydig cells

LH

15

what is function of leydig cells

produce T

16

what is epidydimis

highly convoluted tubule packed with vascular CT

17

what is epidyd lined with

pseudostratified columnar epithelium with stereocilia

18

what are stereocilia actually

clumps of microvillae

19

function of epidyd

sperm storage and maturation

20

what are 3 layers of vas def.

1. mucosa - pseudostrat columnar
2. muscularis - very thick mostly smooth muscle
3. adventitia - CT

21

what surrounds prostate

fibroelastic capsule

22

where do ducts open into

prostatic urethra

23

what are glands lined with

simple to pseudostratified epithelium

24

where are glands located

posterior aspect of prostate

25

where is cancer

posterior porstate

26

what are zones of prostate

1. urethral
2. transitional
3. peripheral

27

what zone enlarges in BPH

transitional

28

whatzone gets cancer

peripheral
