Term
| Gonadotropic releasing hormone (GnRH) |
|
Definition
| Source: Hypothalamus, Stimulates the release of anterior pituitary hormones FSH and LH |
|
|
Term
| Follicle stimulating hormone (FSH) |
|
Definition
| Source: Anterior pituitary gland, Stimulates follicle growth in the ovaries |
|
|
Term
|
Definition
| Souce: Anterior pituitary gland, 1)supports maturation of follicle 2)LH surge triggers ovulation 3)supports maturation of corpus luteum by stimulating production of progesterone |
|

Term
|
Definition
| Source: Follicular cells or fat, Stimulates proliferative phase of endometrium, which means estrogen regenerates of the functional layer of the endometrium after menstruation-responsible for the development of secondary sexual characteristics in females |
|
|
Term
|
Definition
| Source: Corpus luteum, 1)stimulates the secretory phase of the endometrium 2) affects other parts of the reproductive system (e.g. maintains uterine lining) |
|
|
Term
| Human chorionic gonadotropin (HCG) |
|
Definition
| Source: Placenta (chorion/trophoblast), Maintains the corpus luteum, therefore high levels of progesterone persist and the functional endometrium is maintained. The corpus luteum of pregnancy secretes progesterone until the end of the 4th month of pregnancy-note: in absence of developing embryo the corpus luteum degenerates to form corpus albicans, progesterone declines and the endometrium is shed and menstruation occurs |

Term
| Oxytocin "love hormone" source |
|
Definition
| Source: posterior pituitary gland – the synthetic form is PITOCIN (doctors give this to induce labor) |
|
|
Term
| Oxytocin "love hormone" action |
|
Definition
| Letdown reflex – in lactating (breastfeeding) mothers, oxytocin acts on the mammary glands; Uterine contraction – important for cervical dilation before birth and causes contractions during the second and third stages of labor. |
|
|
Term
|
Definition
| Produced by the corpus luteum of the ovary, the breast, and during pregnancy by the placenta/ chorion |
|
|
Term
|
Definition
| In animals, relaxin widens the pubic bone and facilitates labor; it also softens the cervix (cervical ripening), and relaxes the uterine musculature (thus inhibits uterine contractions). |
|
|
Term
| Human placental lactogen (HPL) |
|
Definition
| Source: placenta, Its structure and function is similar to that of human growth hormone. Stimulates breast development and it modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus |

Term
|
Definition
| Internal organs well developed, the brain can signal for muscles to move, heart development ends, external sex organs begin to form (but the good stuff doesn’t happen until weeks 12-14). |
