spermatogenesis

occurs in seminiferous tubules of testes

results in production of 4 haploid sperm that are genetically different

oogenesis

occurs in the ovaries

results in production of 1 viable egg

seminiferous tubules

(entire thing that is cut)

seminiferous tubules

________ ________ are where sperm are made (aka spermatogenesis)

interstitial cells

follicular cells

nucleus

primordial follicle

Small. Contains egg with nucleus. Single layer of flat follicular cells surrounding the egg

(questioning if there are even follicular cells around it)

primary follicle

Contains larger egg with nucleus. Single layer of cuboidal follicular cells.

secondary follicle

Contains even larger egg (with nucleus) & 2 or more layers of follicular cells

mature follicle

Egg, nucleus, follicular cells, follicle

(it's huge compared to others & has very large fluid around inner circle)

fertilized egg

Clearly define nucleus has disappeared

unfertilized egg

Clearly defined nucleus, looks like a "fried egg"

two cell stage

four cell stage

eight cell stage

morula

Solid compact ball of at least 12 cells

blastula

Appears somewhat blurry and is also darker in the perimeter than in the center. Due to it being a 3 dimensional globe that is hollow in center.

Aka blastocyst
