Chapter28 Flashcards
Reproductive cells (spermatozoa or oocytes) that contain half the normal chromosome complement.
Gametes
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; also called 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 ale reproductive tract, contributing roughly one-third of the volume of semen.
Prostate Gland
A component of the male external genitalia; a copulatory organ that surrounds the urethra and serves to introduce semen into the female vagina; the developmental equivalent of the female clitoris.
Penis
The stiffening of the penis due to the engorgement of the erectile tissues of the corpora cavernous 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; in females, the periodic release of an oocyte from an ovary.
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 process of endometrial sloughing.
Menstruation
The termination of the uterine cycle. The time that ovulation and menstruation cease.
Menopause
An elastic epithelial fold of variable size that partially blocks the entrance to the vagina.
Hymen
The ejection of semen from the penis as the result of muscular contractions of the bulbospongiosus and ischiocavernosus muscles.
Ejaculation
Ejaculation is associated with intensely pleasurable sensations, and experience known as male ______.
Orgasm
The failure of one or both testes to descend into the scrotum by the time of birth.
Cryptorchidism
Painful menstruation.
Dysmenorrhea
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 growth of endometrial tissue outside the uterus.
Endometriosis
The inability to achieve or maintain an erection.
Impotence
The surgical removal of part or all of a breast containing cancerous glandular tissue.
Mastectomy
The examination of breast tissue.
Mammogram
The surgical removal of testis.
Orchiectomy
The surgical removal of a segment of each ductus deferent, making it impossible for spermatozoa to reach the distal portions of the female reproductive tract.
Vascetomy
