Loading flashcards...
1
Fetal membrane that forms a fluid-filled sac around the embryo.
Amnion
2
Stage of early embryonic development; the product of cleavage.
Blastocyst
3
Outermost fetal membrane; helps form the placenta.
Chorion
4
Developmental stage extending from fertilization to the end of the eighth week.
Embryo
5
Mucous membrane lining of the uterus.
Endometrium
6
That portion of the male duct system in which sperm mature. Empties into the ductus (or vas) deferens.
Epididymis
7
Fusion of the sperm and egg nuclei.
Fertilization
8
Developmental stage extending from the ninth week of development to birth.
Fetus
9
Sex or germ cell.
Gamete
10
Primary reproductive organ; i.e., the testis of the male or the ovary of the female.
Gonad
11
Production and secretion of milk.
Lactation
12
Nuclear division process that reduces the chromosomal number by half and results in the formation of four haploid (n) cells; occurs only in certain reproductive organs.
Meiosis
13
Period of life when, prompted by hormonal changes, ovulation and menstruation cease.
Menopause
14
The mulberry-like solid mass of blastomeres resulting from cleavage in the early conceptus.
Morula
15
Immature female gamete.
Oocyte
16
Female reproductive organ in which ova (eggs) are produced; female gonad.
Ovary
17
Culmination of pregnancy; giving birth.
Parturition
18
Temporary organ formed from both fetal and maternal tissues that provides nutrients and oxygen to the developing fetus, carries away fetal metabolic wastes, and produces the hormones of pregnancy.
Placenta
19
Adenohypophyseal hormone that stimulates the breasts to produce milk.
Prolactin
20
External sac enclosing the testes.
Scrotum
21
Fluid mixture containing sperm and secretions of the male accessory reproductive glands.
Semen
22
Highly convoluted tubes within the testes; form sperm.
Seminiferous tubule
23
The process of sperm (male gamete) formation; involves meiosis.
Spermatogenesis
24
Male gamete.
Sperm
25
Male primary reproductive organ that produces sperm; male gonad.
Testis
26
Structure bearing arteries and veins connecting the placenta and the fetus.
Umbilical cord
27
Mature ovarian follicle.
Vesicular (Graffian) follicle
28
Female external genitalia.
Vulva
