Reproductive
Term | Definition |
---|---|
Progesterone | endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. |
Estrogen | the primary female sex hormone. It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. |
Ovulation | the release of egg from the ovaries. |
Implantation | the attachment of the fertilized egg or blastocyst to the wall of the uterus at the start of pregnancy, often delayed in some mammals by several months. |
Uterus | the organ in the lower body of a woman or female mammal where offspring are conceived and in which they gestate before birth; the womb |
Cervix | the narrow passage forming the lower end of the uterus |
Vagina | the muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals |
Testosterone | a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex |
Fetus | an unborn offspring of a mammal, in particular an unborn human baby more than eight weeks after conception |
Vas deferens | the duct which conveys sperm from the testicle to the urethra. |
Semen | the male reproductive fluid, containing spermatozoa in suspension |
Oviduct/Fallopian tube | the tube through which an ovum or egg passes from an ovary |
Epididymis | a highly convoluted duct behind the testis, along which sperm passes to the vas deferens |
Placenta | a flattened circular organ in the uterus of pregnant eutherian mammals, nourishing and maintaining the fetus through the umbilical cord |
Menopause | Ovaries stop producing reproductive hormones gradually, when women are in their 40's -50's. |
Menstruation | also known as a period or monthly, is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. |
Cleavage | indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division |
Differentiation | normal process by which a less specialized cell undergoes maturation to become more distinct in form and function. |
Gestation | the carrying of an embryo or fetus inside female |
Embryo | an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus) |
