Reproductive Phys Flashcards
Gonads produce
Gametes and sex hormones
What are the gametes
Ovary-female
Testes-male
Tissues that have the potential to diffrentiate into male and female tissues
Bipotential tissues
This protin directs development as a male
SRY protein
Urethral folds and groove produce
Urethra
Labia minora
Vagina opening in female
Shaft of penis in male
Genital tubercle produces
Clitoris in female
Glans penis in male
Urethral folds and groove in both
Gonadal cortex
Produces ovary in female
Degenerates in males
Labioscrotal swellings produce
Shaft of penis and scrotum in male
Labia majora in female
Gonadal medulla
Forms testis in males
Degenerates in female
Wolfian duct becomes
Epidydimis,seminiferous tubules and vas deferens in males when testosterone is produced.
Regresses in female
Mullerian duct becomes
Upper half of vagina
Fallopian tube
Uterus
Cervix
Mullerian duct regreses in
males
MIF function
Inhibits formation of mullerian duct
Gmetogenesis begins at this time
in utero
Germ cells are present in embryonic gonad
true
Mitotic divisions in embryonic gonad
Increases the number of germ cells
Meiosis in embryonic gonad leads to
The differentiation of primary ,secondary and haploid gamete
Gonads produce
The main source of peptide hormones and steroids
Main source of sex steroid hormones
Gonads
Why hypothalamus is said to be a pulse generator
Because it produces GnRH
Pattern for hormonal control of reproduction
Hypothalamus —>releases GnRH—->.Anterior pituitary gland–>Produces LH and FSH—>Acts on gonads—>Steroid, peptide hormones and gametes produced
Peptide hormones produced include
Inhibin and activin
