Female Reproductive 15 Flashcards
(275 cards)
breasts; mammary glands
modified sweat glands that produce milk
areola
pigmented area around the breast nipple
lactiferous ducts
channels that carry breast milk to the nipple
lactiferous sinuses
expanded chambers that converge on the nipple surface
lobes of mammary gland
15-20 separate portions of the mammary gland that radiate from the central area deep to the nipple-like wheel spokes and comprise the body of the mammary gland; each is drained by a single lactiferous duct
lobules of mammary gland
subdivisions of the lobes of the mammary gland that make breast milk
nipple
projection on the breast surface through which milk can be secreted
genitalia
external and internal organs of reproduction
ovaries
pair of oval reproductive glands that produce hormones and release oocytes
oocyte
female gamete or sex cell; when fertilized by a sperm, it develops into an ovum and is capable of developing into a new individual
corpus luteum
temporary endocrine gland formed in the ovary that secretes the hormone progesterone during the second half of the menstrual cycle
menstrual cycle
period of time in which an oocyte matures, is ovulated, and enters the uterus through the uterine tubes; during this time, ovarian hormonal secretions effect endometrial changes; if fertilization does not occur, the endometrium is shed and menstrual flow begins; the cycle lasts about 28 days
vesicular ovarian follicles; graafian follicles
fluid-filled sacs in the ovaries in which the primary oocyte matures
ovum; ova
oocyte that has been fertilized by a spermatozoon; an egg cell
uterine tubes; salpinges, fallopian tubes
tubular structures that carry the oocyte from the ovary to the uterus
fimbriae
finger-like extensions of each uterine tube that drape over each ovary
uterus; womb
pear-shaped organ located in the middle of the pelvis that supports a growing embryo and fetus and is the site of menstruation
adnexa
appendages or adjunct parts; the adnexa of the uterus consist of the uterine tubes, the ovaries, and the ligaments that hold them together
endometrium
inner layer that lines the uterus; this layer is shed during menstruation
myometrium
thick, muscular middle layer of the uterus
perimetrium
outer layer of the uterus that covers the body of the uterus and part of the cervix
cervix
tubular, lower portion of the uterus that opens into the vagina
cervical os
vaginal opening of the uterus, also called external os of uterus
fundus
dome-shaped top portion of the uterus that lies above the entrance of the uterine tubes
