Chapter 15: Reproduction Flashcards
Haploid cell that fuses with second haploid cell to effect fertilization and create a zygote.
Gamete
Gamete producing organ.
Gonads
Male gonads.
Testes
Specific location of sperm production.
Seminiferous tubules
Gametes that upon fertilization supply chromosomes but not much else.
Sperm
Tubes that rhythmically delivers sperm from the epididymis to the urethra during ejaculation.
Vas deferens
Source of yellowish fluid that aids in sperm post ejaculation survival and functioning.
Seminal vesicle
Contributor of white, alkaline fluid that makes up one half or more of the volume of semen.
Prostate gland
Semen delivery organ.
Penis
Egg containing spherical clusters of cells where many of these clusters together make up ovaries.
Follicle
An unfertilized egg cell that is receptive to fertilization.
Ovum
Connecting organ between the ovary and the uterus.
Fallopian tube
Location in mammals where fetus gestation occurs.
Uterus
Muscular canal separating the lumen of the uterus from that of the vagina.
Cervix
The mucous membrane lining of the uterus.
Endometrium
Internal female structure directly involved in sexual intercourse and into which sperm is deposited in the course of male ejaculation.
Vagina
Female external genetalia.
Vulva
Well defined sequence of modifications to the egg-producing anatomy of sexually mature but not pregnant females.
Ovarian cycle
Progesterone-secreting structure that is present within ovaries during the secretory phase of the ovarian cycle.
Corpus luteum
Well defined sequence of modifications to the embryo-nourishing anatomy of sexually mature but not pregnant female mammals.
Uterine cycle
Blood discharge from the vagina associated with shedding of the endometrium.
Menses
Time during the uterine cycle of endometrium shedding.
Menstrual phase
Time during the uterine cycle of endometrium regeneration.
Proliferation phase
Time during the uterine cycle when the corpus luteum is producing progesterone.
Secretory phase
Diploid product of gamete fusion.
Zygote
Mitotic division during early animal embryonic development.
Cleavage
Embryonic product of cleavage that consists of a solid ball of cells.
Morula
Hollow ball of cells that forms from the morula during the early embryonic development of mammals.
Blastocyst
Blastocyst attachment to the uterine lining.
Implantation
The transition from antepartum to postpartum.
Parturition
Milk producing organ associated with mammals.
Mammary gland
