Microstructure of the Female Reproductive System

Question 1

CL? H? F? M? L?

Answer 1

CL = Corpus Luteum

H = Hilus

F = Follicles

M = Medulla (lots of blood vessels)

L = Ligament

Question 2

What arrests primary oocyte in meiosis I

Answer 2

by 7th month of fetal development, single layer of flattened follicular cells surround primary oocyte; this encapsulation arrests the first meiotic division until puberty

Question 3

What type of epithelium is found in follicular cells

Answer 3

simple cuboidal epithelium

NB: also called germinal epithelium; named so because originally thought to give rise to germ cells

Question 4

What kind of epithelium is found lining the ovaries

Answer 4

simple cuboidal epithelium that is continuous with meothelial lining of peritoneal cavity; egg released directly into peritoneal cavity before being swept up by fimbrae

Question 5

vagina

Answer 5

Latin, “sheath, scabbard”

Question 6

relationship between follicular cells and granulosa

Answer 6

Flattened follicular cells surrounding primary follicle are changing to granulosa cells (simple cuboidal)

Question 7

Green arrow? Blue arrows?

Answer 7

Green = primordial follicle (surrounded by flattened follicular cells)

Blue = primary follicle

Question 8

Green arrows? Blue arrow?

Answer 8

Green = primordial follicle (flattened follicular cells surround it)

Blue = primary follicle
