HLSC 2F95 Lecture Notes - Activin And Inhibin, Microvillus, Plasmin
Document Summary
Accessory sex organs testes - spermatozoa androgens ovaries - ova - estrogens. The reproductive systems are structured to produce haploid gametes from each sex. The female reproductive system is structured to potentially Epididymus, ductus deferens, seminal vesicles, prostate gland, bulbourethal gland, scrotum, penis. Male reproductive system - 2 - fig. Testes (under cold temperatures & fight or flight conditions) become closer to be protected (body warmth) Different lobules contains within the testes, that have long tubule structure. We reduce the number of tubes, eventually turning into one, there is vascularization. There are cells within of the wall and periphery. Only half the cells move up, after meiosis - there is a reduction (haploid number of chromosomes) Prevents active immunological cells from attacking haploids - so they can mature into spermatozoids. Division of spermatogonia & meiosis of spermatocytes. Support for spermatogenesis (fsh & testosterone) support for spermiogenesis. Secretion of inhibin - represses production of fsh & gnrh.
