Spermatogenesis and Oogenesis Flashcards
Where does spermatogenesis happen
Seminiferous tubules
When does spermatogenesis start
Puberty
What are the three stages of spermatogenesis
Proliferation
Meiosis I and II
Differentiation/maturation
What happens during proliferation - spermatogenesis
formation of spermatogonia and then into spermatocyte
When does oogenesis start
Before birth
What are the 3 stages of oogenesis
Proliferation
Development
Resumption of meiosis
Definition of Folliculogenesis
Growth and development of follicles
Where does Folliculogenesis occur
Primary oocyte
What are the 3 types of follicles
Primordial
Primary
Antral/Graafian
Where does primordial follicle develop
Primary oocyte
What does a primordial follicle look like
Primary oocyte surrounded by single layer flattened pre granulosa
What happens to the granulosa cells in primary follicles
Turn cuboidal + increase in number
What’s a polar body
Haploid cell with half genetic but doesn’t have enough cytoplasm to become oocyte
What happens to follicle at graafian follicles
Fluid fills between granulosa cells - antrum
