5th week
chromatin is located in
diploid cell
chromatin turns into?
chromosomes
the spindle fiber disappears and the nuclear membrane reforms around the chromosome
telophase 1
the sister chromatids of each chromosome separates and move to opposite poles.
anaphase II
produced by the Leydig cells which causes wollfian duct to develop into sperm transport system epididymis, vas deferens and seminal vesicle
Tesrosterone
Both boys and girls begin dramatic development and maturation of reproductive organs at approximately
12 – 13 years
serves as gonadostat or is set to “turn on” gonad functioning.
hypothalamus

occurs approximately two years after thelarche
Menarche
are the hormones responsible for muscular development, physical growth, and the increase in sebaceous gland secretions that cause typical acne in both boys and girls during adolescence.
Androgenic Hormones
In males, androgenic hormones are produced by the ?
Adrenal Cortex and testes
In females, androgenic hormones are produced by the ?
adrenal cortex and ovaries
The level of the primary androgenic hormone, testosterone, is low in males until puberty (between ages 12 and 14 years) when it rises to influence pubertal changes in the testes, scrotum, penis, prostate, and seminal vesicles; the appearance of male pubic, axillary, and facial hair; laryngeal enlargement with its accompanying voice change; maturation of spermatozoa; and closure of growth plates in long bones
adrenarche
When triggered at puberty by FSH, ovarian follicles in females begin to excrete a high level of the hormone
estrogen
