Slide9Spermatogenesis
Starts with 1 “spermatocyte”Primary germ lineEnd up with 4
spermatidsHow many chromosomes are in 1
spermatocyte?How many chromosomes are in 1 spermatid?
Slide10This meiosis happens in seminiferous tubules
Slide11Seminiferous tubules
Lumen surounded by Sertoli Cells
Help maintain liquid environment of lumen for sperm to developPrevent blood from traveling to lumen
Slide12Slide13Slide14Gap Junctions of sertoli cells
Mitosis of primary spermatocye happens above gap junction
Meiosis happens below gap junction between cell membranes
Slide15Hormones involved
Sertoli cells release messengers in responseTestosterone (T)Follicle Stimulating Hormone (FSH)
Luetenizing Hormone (LH)Gonadotrpoin
Releasing Hormone (GnRH)
Slide16Leydig Cells
The ones that generate and release Testosterone (T)T essential for proliferation and differentiation of sperm
Slide17Hypothalamus – Pituitary Gland
Slide18Slide19Quick write: How does the hypothalamus affect the testis?
Slide20Spermatogenesis
Must be cooler than body temperature
