Mitosis vs Meiosis review

• Meiosis • Mitosis

Describe Structure and Function of the gonads and accessories

• Testicles• Penis• Seminal Vesicles• Epididymis Seminiferous

Tubules

• Vas Deferens • Ejaculatory

Duct• Prostate Gland • Bulbourethral

gland Chapter 27

Spermatogenesis

• Starts with 1 “spermatocyte”– Primary germ line

• End up with 4 spermatids

• How many chromosomes are in 1 spermatocyte?

• How many chromosomes are in 1 spermatid?

This meiosis happens in seminiferous tubules

Seminiferous tubules

• Lumen surounded by Sertoli Cells• Help maintain liquid environment of lumen for

sperm to develop• Prevent blood from traveling to lumen

Gap Junctions of sertoli cells

• Mitosis of primary spermatocye happens above gap junction

• Meiosis happens below gap junction between cell membranes

Hormones involved

• Sertoli cells release messengers in response– Testosterone (T)– Follicle Stimulating Hormone (FSH)– Luetenizing Hormone (LH)– Gonadotrpoin Releasing Hormone (GnRH)

Leydig Cells

• The ones that generate and release Testosterone (T)

• T essential for proliferation and differentiation of sperm
