Cards

Term
Mesoderm
Definition
embryo's middle layer from which the first reproductive tissue arises at about 5 weeks after conception.
Term
Gonad
Definition
The sex gland; the first structure formed from the mesoderm.
Term
Spermatozoa
Definition
Sperm. Not produced in testes until puberty.
Term
Oogonia
Definition
Underdeveloped egg cells that develop into oocytes.
Term
Oocytes
Definition
Fully developed egg cells formed from oogonia. There are 2 to 4 million oocytes present in the ovary at time of birth.
Term
Vulva
Definition
(pudendum femininum) the portion of the femal external genitalia that lies posterior to the mons pubis. Consists of labia majora, labia minora, clitoris, vestibule of the vagina, vaginal opening, and Bartholin's glands.
Term
Mons Pubis
Definition
The layer of sub-q tissue anterior to the genitalia in front of the symphysis pubis.
Term
Labia Majora
Definition
Two folds of tissue that lie lateral to the genitalia and serve to protect the delicate tissues between them. They become less prominent after each pregnancy. Have an extensive lymphatic network and highly vascularized, wich leads to an enhanced capacity to spread diseases (such as cancers).
Term
Labia Minora
Definition
Two folds of tissue that lie within the labia majora and converge near the anus to form the fourchette.
Term
Fourchette
Definition
Tense fold of mucous membrane atthe posterior opening of the vagina.
Term
Prepuce
Definition
Clitoral hood; small fold of skin that partially covers the glans (head) of the clitoris.
Term
Smegma
Definition
Cheese-like fatty substance with distinctive odor secreted by clitoris.
Term
Female Circumcision
Definition
Removal of clitoris adn other external genitalia in ritualistic process in some cultures.
Term
Meatus
Definition
Urethral opening.
Term
Hymen
Definition
A connective tissue membrane that encircles the vaginal introitus.

Definition
Incision made to enlarge perineal opening to allow delivery of a fetus.
Term
Adnexa
Definition
Structures adjacent to the uterus.
Term
Ova
Definition
Female gametes prodcued by ovaries.
Term
Oogenesis
Definition
Pocess of meiosis for egg cell formation resulting in the formation of a mature eggs in ovary. Occurs at monthly intervals.
Term
Oogonium
Definition
Egg-generating cell contained within ovarian follicles.
Term
Graafian Follicle
Definition
A mature ovarian follicle containing the secondary oocyte.
Term
Uterine Tubes/Oviducts
Definition
the two fallopian tubes, each about 4 inches (10 cm) in length.
Term
Cilia
Definition
Hairlike projections (in fallopian tubes) to assist in directing the ovum toward the uterus.
Term
Tubal Ligation
Definition
Peramanent sterilization at the third division of the fallopian tube (the isthmus)--nearest the uterus.
Term
Gravid
Definition
Pregnant
Term
Dysmenorrhea
Definition
painful menstruation
Term
Myometrium
Definition
Middle layer of the uterus composed of layers of smooth muscle that extend in three directions (important in facilitatng effective uterine contractions during labor and birth).
Term
Cervix
Definition
"Neck" of uterus; the lower, narrow end.
Term
Fundus
Definition
Uppermost section of the uterus.
Term
Operculum
Definition
Mucus plug in cervix to protect the pregnancy from outside pathogens.
Term
Squamocolumnar Junction
Definition
The junction of the vaginal portion of the cervix and the cannal portion.
Term
Rugae
Definition
small ridges thatline the vagina
Term
Linea Terminalis
Definition
the pelvic brim that divides the "false pelvis" and the "true pelvis"
Term
Pelvic Outlet
Definition
The lowest portion of the true pelvis.
Term
Pelvimetry
Definition
Measurement of the pelvis to predict the feasiblity of a vaginal birth.
Term
Trial of Labor
Definition
Allowing uterine contractions in order to evaluate labor progress and assess feasibility of vaginal birth.
Term
Obstetrical Conjugate
Definition
The narrowest portion of the pelvic inlet adn should measure at least 4.5 inches (11.5 cm). Once the fetus has passed this landmark it is "engaged" in the pelvis.
Term
Spermatogenesis
Definition
the process of meiosis in the testes to produce sperm cells.
Term
Gonadotropins
Definition
Gonad-stimulating hormones; include Follicle-Stimulating hormone (FSH) and Luteinizing hormone (LH). Help regulate menstrual cycle.
Term
Trophoblast
Definition
outermost layer of the developing blastocyst. Produces human chorionic gonadotropin (hCG). hCG levels are measured to diagnose pregnancy. Also keeps progesterone and estrogen elevated until placenta has developed enough to assume that function.
Term
Corpus Luteum
Definition
Remainder of ovarian follicle after ovulation and maintained by trophoblast.
Term
Thelarche
Definition
Appearance of breast buds. First stage of sexual maturity in girls.
Term
Menarche
Definition
First menstrual period.
Term
Ovulation
Definition
release of ovum from ovary
Term
Corpus Luteum
Definition
"yellow body" that remains in ovary after ovulation and produces progesterone.
Term
Menstruation
Definition
periodic discharge of bloody fluid from the vagina during woman's reproductive years.
Term
Menstrual Cycle
Definition
Changes in uterus, cervix, and vagina associated with menstruation and the intermenstrual period.
Term
Spinnbarkheit
Definition
the elasticity of cervical mucus that a woman can assess by stretching the mucus between her fingers. (Fun!) :P Increases during ovulation.
Term
Ferning Capacity
Definition
crystallization of cervical mucus. Increases during ovulation.
Term
Climacteric phase
Definition
decline in ovarian function and associated loss of estrogen and progesterone production.
Term
Anovulatory
Definition
No ova are released from ovary.
Term
