Reproduction Flashcards
Myometrium
muscular layer of uterus, responsible for contractions
Endometrium
inner lining of where the placenta attaches and that sheds every month
FSH (follicle stimulating hormone)- Oogenesis
hormone that triggers the development of the follicle, thickening of the follicle wall, and the secretion of follicular fluid. involved in the first part of the menstrual cycle
Estrogen- oogenesis
hormone that is released by the follicular wall that turns off the secretion of FSH, which signals to hypothalamus to release LH.
LH (leutinizing hormone)- oogenesis
hormone that stimulates the completion of meiosis 1 in the oocyte and causes ovulation and helps grow the corpus luteum
Effects of Estrogen- oogenesis
- Thickening of endometrium
- Growth of blood vessels in endometrium
- Increase in FSH receptors in follicle
- Inhibition of FSH secretion and stimulation of LH
Progesterone- oogenesis
hormone secreted by corpus luteum that maintains the endometrium and its blood vessels, and inhibits production of FSH and LH
GnRH (gonadotropic releasing hormone)
hormone that is released by the hypothalamus to trigger gametogenesis
Corpus Luteum
transformed version of the follicle that releases progesterone
Seminal vesicle
part of male reproductive system that creates prostaglandins and adds fructose to semen
Prostoglandins
chemicals that allow for small uterine contractions to help move sperm through the uterus
Prostate gland
part of the male reproductive system that releases alkaline fluid to protect sperm in acidic vaginal environment
Acrosome
part of sperm that helps it during process of fertilization to break through the membranes
Sertoli cells
cells in male reproductive system that release nutrients which help primary spermatocytes go through meiosis 1
FSH (follicle stimulating hormone)- spermatogenesis
hormone responsible for stimulating sertoli cells to release the nutrients needed to change primary spermatocytes into secondary spermatocytes
Where is all of the mitochondria in a sperm?
in the midpiece
Spermatogonia
2n germ cells that undergo mitosis to create infinite spermatocytes
