Reproductive System Flashcards
_ (hormone) is responsible for maintaining pregnancy by maintaining the corpus luteum
human chorionic gonadotropin
_ maintains pregnancy by secreting estrogens and progesterone which in term prevent menstruation
corpus luteum
_ happens when levels of progesterone and estrogen levels drop
menstruation
chromosome number [is] _ from one generation of humans to the next
consistent
_ leads to production of testosterone and estrogen; also triggers ovulation
luteinizing hormone (LH)
rising and falling levels of hormones in ovaries ensure uterus is prepared incase of _ (in uterine tubes)
fertilization
_ is involved in arousal
nervous system
erection is under _ control; orgasm and ejaculation are under _ control
parasympathetic; sympathetic
_ (in gastrulation) epithelium and neural structures
ectoderm
_ (in gastrulation) involve motion, such as skeletal muscle, bones etc.
mesoderm
_ (in gastrulation) internal structures, such as GI, urinary and respiratory
endoderm
estrogen and progesterone levels _ throughout pregnancy
increase
development of the primary germ layers is _
gastrulation
_ involves scrotum, testis, epididymis, vas deferens, urethra, seminal vesicles, prostate and bulbourethral gland
male reproductive system
_ is production of sperm
spermatogenesis
_ involves follicles
oogenesis
_ produces clear mucus to neutralize acid
bulbourethral gland
_ is a mucosal, incomplete partition in distal vaginal orifice
hymen
_ includes mons pubis, labia, clitoris
vulva
_ (on breasts) are under ANS
areola
_ (follicular phase) is shedding of functional layer of endometrium
menstrual phase
_ (follicular phase) is rebuilding of functional layer of endometrium
proliferative phase
_ (luteal phase) begins after ovulation; enrichment of blood supply to prepare endometrium for embryo
secretory phase
interstitial endocrine cells (Leydig cells) make _
testosterone
