| Question | Answer |
|---|---|
| Hormone released by the hypothalamus that stimulates the anterior pituitary to secrete LH and FSH. | Gonadotropin-releasing hormone |
| Hormone from the anterior pituitary that stimulates testosterone secretion in males and causes ovulation/corpus luteum formation in females. | Luteinizing hormone |
| Hormone from the anterior pituitary that supports spermatogenesis in males and causes follicles to begin development in females. | Follicle-stimulating hormone |
| Hormone produced by ovarian follicles and corpus luteum that causes proliferation of endometrial cells and development of secondary sexual characteristics. | Estrogen |
| Hormone secreted by the corpus luteum that causes enlargement of endometrial cells, secretion of fluid from uterine glands, and maintenance of the pregnant state. | Progesterone |
| Hormone from the posterior pituitary that causes contraction of uterine smooth muscle and milk letdown. | Oxytocin |
| Hormone secreted by the placenta that maintains the corpus luteum during the first trimester of pregnancy. | Human chorionic gonadotropin |
| Uses constant levels of estrogen and progesterone to prevent the release of FSH and LH, thus preventing ovulation. | Hormonal Birth Control |
| The stage of development at which individuals become sexually mature. | Puberty |
| Traits that develop at puberty, such as breast development in females or increased larynx size in males. | Secondary Sex Characteristics |
| Triggered by contact with the zona pellucida, causing sperm to secrete digestive enzymes that break down the zona pellucida glycoprotein membrane. | Acrosome reaction |
| An assisted reproductive technology ("in glass") where fertilization takes place outside of the body. | In vitro fertilization |
| The stage of development involving cleavage from fertilized oocyte to blastocyst. | Pre-embryonic development |
| A pre-embryonic stage consisting of 16 cells. | Morula |
| A pre-embryonic stage (70–100 cells) that hatches and implants into the endometrium. | Blastocyst |
| The outer layer of the blastocyst. | Trophoblast |
| The cluster of cells inside the blastocyst that will become the embryo. | Inner cell mass |
| The process where the blastocyst rotates and implants into the endometrium of the uterus. | Implantation |
| A temporary organ that mediates diffusion of nutrients, respiration, and hormone secretion during pregnancy. | Placenta |
| Finger-like projections of the chorion that extend into the maternal blood supply for nutrient and gas exchange. | Chorionic villi |
| Connects the fetus to the placenta, containing the umbilical artery and vein. | Umbilical cord |
| The fluid surrounding the embryo/fetus. | Amniotic fluid |
| An embryonic germ layer formed from the epiblast. | Ectoderm |
| An embryonic germ layer formed by displacement of hypoblast cells. | Mesoderm |
| A fetal shunt connecting the aorta with the pulmonary artery, shunting blood away from the lungs. | Ductus venosus |
| Stage involving the dilation of the cervix (to $>10~cm$)120120120120. | Stage 1 of Childbirth (Dilation) |
