Endocrine System and Reproductive histology Flashcards

Question

Straight tubules

Answer 1

Lined with only Sertoli cells Open into RETE testis Cuboidal epithelium with under lying DCT

Answer 2

Network of channels Lined with cuboidal epithelium with DCT Single apical cilium and few Microvilli

Answer 3

Leads to head of epidymis Lined with psuedostratified columnar epithelium, cilia With groups of nonciliated cuboidal cells with Microvilli Some smooth muscle

Answer 4

``` Highly coiled tube Pseudo stratified columnar epithelium -rounded basal cells - columnar cells with Stereocilia or principal cells Smooth muscle surrounds 4-5 meters Maturation of sperm occurs ```

Answer 5

Psuedostratified columnar epithelium with sparse Stereocilia 3 layers of smooth muscle, longitudinal circular longitudinal Ampulla- dilated area where epithelium is thicker and folded Ejectulatory duct- ductus deferens in prostate gland after seminal vesicles join, no muscular layers

Answer 6

Prostatic- transitional epithelium Membranous- stratified columnar or pseuodo Spongy or penile- psuedostratified or stratified squamous

Answer 7

Seminal vesicles Prostate glands Bulbourethral glands

Answer 8

``` Simple columnar epithelium or pseudo Rich in secretory granules Joins with ampulla to make ejactulatory duct Folds in lumen increase surface area 2 smooth muscle layers Make 60% of fluid which is sugar based ```

Answer 9

30-50 tubuloaveolar glands in a muscular fiber stroma Empties into prosthetic urethral Contains prostatic concretions- deposited gags and glycoproteins Fluid will activate sperm Simple or pseudo stratified columnar epithelium

Answer 10

Cowper's glands Compound tubuloaveolar glands Mucous secreting simple columnar epithelium Empty into proximal penile urethra

Answer 11

Paired corpora cavernosa Single corpus spongiosum Lined with psuedostratified columnar Surrounded with DCT or the tunica albuginea

Answer 12

Estrogen : growth | Progesterone : prepares the uterus for pregnancy and mammary glands for milk

Answer 13

Produce ovum

Answer 14

Germinal epithelium Tunica albuginea Cortex- ovarian Medulla- blood vessels and nerves

Answer 15

First month of fetal development migrate to gonadal ridge Divide via mitosis

Answer 16

Proliferate via mitosis Undergo meiosis at third month Enter prophase of meiosis one, stop Arrested cells are primary pockets

Answer 17

Surrounded by flattened cell called follicular cell Creates primordial follicle

Answer 18

``` Primordial follicles Growing follicles - primary follicle: unilaminar or multilaminar -secondary follicle Mature or Graafian follicles -will ovulate secondary oocytes ```

Answer 19

Make up the stratum granulosum Stratified epithelium around a Late or Multilayered primary follicle Zone Pollucida forms at this point

Answer 20

Is a sheath of connective tissue from strongly cells Theca interna: secrete estrogen Theca external: smooth muscle exterior Both of these sit a top the basal lamina which is atop the follicular cells

Answer 21

Follicular growth continued and a ANTRUM IS MADE ANTRUM FOLLICLE At this point granulosa cells form the corona radiata Still has a primary oocyte arrested in prophase one

Answer 22

Mature follicle 10 mm in diameter to 30 mm Largest secondary follicle Only 1 or 2 produces per month Ovulation next to come Will finish meiosis to become the secondary oocyte after ovulation

Answer 23

Will form when the Graafian follicle ovulated the oocyte The oocyte will finish meiosis 1 and arrest at metaphase of meiosis 2

Answer 24

Granulosa cells after ovulation will grow Form a blood clot Begin to produce progesterone

Answer 25

Increase only slightly in size Come from theca interna Continue to produce estrogen

Answer 26

Made of granulosa lutein cells and theca lutein cells Basically a follicle after ovulation Initially a corpus hemorrhagicum= blood clot Degenerate in 10 days with no pregnancy Degenerates in 9 months with pregnancy

Answer 27

Wall is folded mucosa and thick muscularis SM with serosa Simple columnar epithelium 2 cells: Ciliated columnar cells move oocyte Secretory cells- peg cells produce nutritive fluid covering epithelium

Answer 28

``` 1. Perimetrium Outermost serosa or adventitia 2. Myometrium Middle smooth muscle 3. Endometrium -Simple columnar epithelium with ciliated and pegg cells -basal deep layer -functional layer handles ovarian hormones ```

Answer 29

Narrow end of uterus ``` Endometrium differences: Not sloughed in menstration Contains cervical glands Transformation zone- simple columnar to non keritanized squamous =squamocolumnar junction ```

Answer 30

Wall has mucosa, muscular, and adventitia Nonkeritanized stratified squamous Inner circular and out longitudinal muscle

Answer 31

Modified tubuloaveolar sweat glands Secrete milk Merocrine and apocrine mechanisms
