Histology

Question 1

what are seminiferous tubules surrounded by?

Answer 1

tunica albergia

Question 2

what are the endocrine glands of the male reproductive system?

Answer 2

seminal vesicles and prostate

Question 3

what are the exocrine glands of the male reproductive system?

Answer 3

Lydia cells - between the seminiferous tubules

Question 4

what is the prostate gland composed of? what are the zones it is split into?

Answer 4

glandular tissue and stroma

peripheral zone -70%
transitional zone
central zone

Question 5

what type of cancer is most common in the prostate - why? how does it appear under the microscope?

Answer 5

§adenocarcinoma = tumorous malignancy of the glandular tissue - prostate is made of glandular tissue

appears as closely packed abnormal small glands

Question 6

what are the two types of erectile tissue? where are they located?

Answer 6

dorsal paired corpus cavernous

single mental corpus spongiosum

Question 7

what is the structure of erectile tissue?

Answer 7

irregular and interconnected vascular channels

Question 8

what type of cells surround the scrrotum? why?

Answer 8

mesothelium

collected as the testes descend from the peritoneal cavity

Question 9

what are three reasons for male infertility?

Answer 9

abnormal sperm formation
poor motility
aberrant number of chromosomes in the sperm head

Question 10

what is the structure of the ovary?

Answer 10

inner cortex - contains the follicles - embedded in storma - spindle like fibroblast cells

outer medulla - loose CT and the hilum

Question 11

what type of cells coat the ovary?

Answer 11

cuboidal (germinal) epithelium

continuous with the peritoneal epithelium

Question 12

what is the structure of the primordial follicle?

Answer 12

oocyte coated in a single layer of flattened follicular cells
embedded within the cortex

Question 13

what is the structure of the primary follicle?

Answer 13

stratified follicular cells
granulated cytoplasm
thick layer of glycoproteins - form the zona pellucida
stromal cells become the Theca

Question 14

what is the structure of the secondary follicle?

Answer 14

cells proliferate - forming the fluid filled antrum
follicular cell become flattened with growth
genulosa cells become the thickened cumulus ooporus
theca splits into the theca externa and theca interns - which produces oestrogen

Question 15

what is the structure of the tertiary follicle?

Answer 15

GRAFFIAN FOLLICLE - buldges from the ovary - surrounded by the cumulus oophorus
ruptures from the ovary to release oocyte into the peritoneal cavity - close to the fallopian tubes

Question 16

what is the structure of the cells of the cervix?

Answer 16

endocervix - columnar cells - secrete mucus
ectocervix - stratified squamous cells - protects uterus from vagina acid. connective tissue layer allows expansion during childbirth

Question 17

what are the parts to the fallopian tubes?

Answer 17

vibrate, infundibulum, ampulla, isthmus

Question 18

what are the fallopian tubes line by?

Answer 18

muscularis - smooth muscle

ciliated columnar epithelium

Question 19

what type of cells line the vagina

Answer 19

non-keratinising stratified squamous epithelium to protect the walls
connective tissue wall with fibrous and elastic tissue and smooth muscle - allow distension during pregnancy
