Ch. 28 Vocab Flashcards
reproductive organs that produce gametes and hormones
gonads
the fluid ejaculate that contains spermatozoa and the secretions of accessory glands of the male reproductive tract
semen
a cell whose meiotic divisions will produce a single ovum and three polar bodies
oocyte
the functional product of meiosis II, produced after the fertilization of a secondary oocyte
ova/ovum
a male gamete; aka sperm
spermatozoa
the loose-fitting, fleshy pouch that encloses the testes of the male
scrotum
spermatozoon production
spermatogenesis
a muscular tube that carries urine from the urinary bladder to the exterior
urethra
an accessory gland of the male reproductive tract, contributing roughly one-third of the volume of semen
prostrate gland
a component of the male external genitalia; a copulatory organ that surrounds the urethra and serves to introduce semen into the female vagina
penis
the stiffening of the penis due to the engorgement of the erectile tissues of the corpora cavernosa and corpus spongiosum
erection
ovum production
oogenesis
the release of a secondary oocyte, surrounded by cells of the corona radiata, after the rupture of the wall of a tertiary follicle
ovulation
the muscular organ of the female reproductive tract in which implantation, placenta formation, and fetal development occur
uterus
the inferior portion of the uterus
cervix
a muscular tube extending between the uterus and the vestibule
vagina
the mucous membrane lining the uterus
endometrium
the ejection of semen from the penis as the result of muscular contractions of the bulbospongiosus and ischiocavernosus muscles
ejaculation
the failure of one or both testes to descend into the scrotum by the time of birth
cryptorchidism
painful menstruation
dysmenorrhea
the growth of endometrial tissue outside the uterus
endometriosis
the failure of menarche to appear before age 16, or a cessation of menstruation for six months or more in a female of reproductive age
amenorrhea
the inability to achieve or maintain an erection
impotence
the use of X-rays to examine breast tissue
mammography
the surgical removal or part or all of a breast containing cancerous glandular tissue
mastectomy
the surgical removal of a testis
orchiectomy
the surgical removal of a segment of each ductus deferens, making it impossible for spermatozoa to reach the distal portions of the male reproductive tract
vasectomy
intensely pleasurable sensations
orgasm
the time that ovulation and menstruation cease; decline in circulating concentrations of estrogens and progesterone and a sharp and sustained rise in the production of GnRH, FSH, and LH
menopause
an elastic epithelial fold of variable size that partially blocks the entrance to the vagina
hymen
the process of endometrial sloughing
menstruation
reproductive cells that contain half the normal chromosome complement
gametes
