Flashcards in Histology - Male Reproductive System Deck (30)
1

seminiferous, open, euchromatic -nucleolus

Sustentacular cell

1

“checkerboard” nucleus, middle layer

Primary spermatocyte

2

low back pain, urethral discharge, fever. Expressed prostatic secretions (EPS) culture

Prostatitis

3

Testis Septa

CT that divides testis into lobules

3

the specific location of meiosis, and the subsequent creation of gametes, namely spermatozoa.

Seminiferous tubules

3

tumors that arise from sustentacular cells or interstitial cells

Sex cord-stromal tumors

4

Testis dense CT capsule

Tunica albuginea

6

inflammatory response within IT of testis (e.g., viral mumps in adults, syphilis)

Orchitis - scarring may cause infertility, T production often not significantly affected

7

produce sperm

spermatogenic cells

8

Semiferous epithelium, 3 layers

Seminiferous (germinal) epithelium, basement membrane, tunica propria

9

nuclei along the BM

Spermatogonia

9

Found from transitional zone. Associated with DHT, stromal cells convert T to DHT, dysuria, secondary UTIs (urine retention)

Benign prostatic hyperplasia (BPH)

10

have the appearance of a mucus-secreting gland. lubricates the urethra with pre-seminal mucus

bulbourethral glands

12

produce testosterone (T)

interstitial cells (of Leydig)

13

defining histologyical feature of prostate gland

prostatic concretions

14

testis are responsible for…

spermatogenesis: exocrine (holocrine) secretion of sperm AND steroidogenesis: endocrine secretion of testosterone

15

yield primary spermatocytes by mitosis…

spermatogonia

16

disruption of the B-T barrier, antisperm antibodies (ASA)

Immune infertility

17

The seminiferous tubules are formed from…

primitive sex cords. It is the medullary cords which develop into the seminiferous tubules and the cortical cords regress. The cords were formed from the gonadal ridge.

18

Interstitial tissue (IT) loose connective tissue stroma that contains…

fenestrated capillaries, interstitial cells (of Leydig): produce testosterone (T)

20

Tumors that arise from spermatogenic cells;

Germ cell tumors, most common (95%).

21

regulates glandular epithelium growth and metabolism

Prostatic acid phosphatase (PAP)

22

small, dark nucleus, near lumen

Spermatid

23

produce ABP, MIS, inhibin, fructose-rich fluid

sustentacular (Sertoli) cells

24

days until the effects of an antispermatogenic agent are fully observable

86 days, 74 in testis, 12+ to mature in epididymis

25

Formed by tight junctions between sustentacular cells

Blood-testis barrier. Sequesters testosterone in luminal compartment -necessary for spermatogenesis. Gap junctions coordinate activity.

26

Seminiferous tubules epithelium

sustentacular or Sertoli cells, which are tall, columnar type cells that line the tubule.

27

primary spermatocyte divides meiotically into …

two secondary spermatocytes. Each secondary spermatocyte then completes meiosis as it divides into two spermatids which developninto mature spermatozoa (sperm cells).

29

Seminiferous (germinal) epithelium:

spermatogenic cells and sustentacular cells

30

most resistant to BPH, prostatitis, & cancer

Central zone
