Repro Flashcards
Function of Sertoli Cells
protect and nurture sperm
Function of Leydig cells
testosterone synthesis
Syngamy
fusion of spermatozoa and ova
Male gametes
spermatozoa
Female Gametes
ova
Result of first meiotic division in sperm development
secondary spermatocyte
bindin
protein on surface of sperm that attaches to receptors on the zona pellucida surrounding the ovum
Acrosome
enzymes used to penetrate ovum with hydrolytic activity
What does LH do in males
tell interstitial cells to release testosterone
What does FSH do in males
Tells sertoli cells to release inhibin
Function of inhibin
reduce FSH release
Dihydroxytestosterone leads to
development of male genitalia
What does wolfiann duct become
epididymis, seminal vesicles, and vas deferens
What does mullerian duct become
uterine tubes, uterus, and vagina
What hormone stimulates release of LH and FSH
Gonadotropin releasing hormone
Function of FSH in Women
stimulates granulosa cells to secrete estrogen
What does LH do in women
Stimulate formation of corpus luteum and progesterone secretion
What are the products of first meiotic division in oogenesis
secondary oocyte and small polar body
What is the name for oocyte and granulosa cells together
follicle
Zona Pellucida
protective layer of mucopolysaccharides
Thecal Cells
Respond to LH to secrete estrogen
What is a mature follicle called
Graafian follicle
During ovulation what occurs
Graafian follicle bursts, secondary oocyte released with zona pellucida and granulosa cells into fallopian tube
Corona Radiata
The granulosa cells surrounding secondary oocyte during ovulation
