Female Reproductive
ovulation
"the pill" prevents
Meiosis I
(completed by one primary oocyte each month in response to LH surge)
secretory phase
Begins immediately after ovulation. Enrichment of the blood supply and glandular secretion of nutrients prepare the endometrium to receive an embryo.
D
During the secretory phase of the uterine cycle __________. A. the functional layer of the endometrium regenerates B. ovulation occurs C. the endometrium is shed D. the endometrium prepares for implantation
the endometrium prepares for implantation
During the secretory phase of the uterine cycle, __________.
1
How many functional gametes are produced by oogenesis?
D
In females, the _______ is (are) the homologous structure to the glans penis in males. A. vagina B. labia majora C. cervix D. clitoris
B
Ovulated oocytes enter the uterine tubes ________. A. directly, from contact with the ovary B. via undulations of the fimbriae that draw in the oocyte C. via diffusion D. via muscular contractions of the infundibulum expelling the oocyte at a rate of 200 m/s
False
Ovulation occurs near the end of the ovarian cycle.
Uterus
Receive, retain, nourish fertilized ovum
A
The _______ of the uterus receives the embryo and provides nourishment until the placenta is formed. A. endometrium B. myometrium C. perimetrium D. epimetrium
C
The __________, a layer of the endometrium, is shed during each menstruation and is then regenerated by the __________. A. stratum functionalis; myometrium B. stratum basalis; stratum functionalis C. stratum functionalis; stratum basalis D. myometrium; perimetrium
Ovulation
The follicle ruptures and the oocyte is expelled from the ovary
proliferative phase
The functional layer of the endometrium is rebuilt.
menstrual phase
The functional layer of the endometrium is shed.
D
The superior portion of the uterus is called the ______. A. isthmus B. cervix C. ampulla D. fundus
ovulation
What event coincides with the transition from the proliferative phase to the secretory phase?
fallopian tube
What part of the female duct system is the usual site of fertilization of the ovulated oocyte?
LH
Which hormone is absolutely necessary for ovulation to occur?
myometrium
Which layer of the uterine wall is made of smooth muscle?
D
Which layer of the uterus is the site for implantation of a fertilized egg? A. myometrium B. perimetrium C. stratum basalis of the endometrium D. stratum functionalis of the endometrium
B
Which of the choices below is not a function of the vagina? A. serves as the birth canal B. serves as a passageway for the primary oocyte C. serves as a passageway for menstrual flow D. receives semen from the penis during sexual intercourse
secondary oocyte
Which of the following cells is released during ovulation?
C
Which of the following is FALSE regarding the vagina of an adult female? A.The vagina is also called the birth canal. B.The vaginal mucosa lacks glands. C.The pH of the adult vagina is alkaline. D.The mucosa of the vagina is stratified squamous epithelium.
clitoris
Which structure of the female's external genitalia has erectile tissue like the penis?
progesterone
affects mood - reduces anxiety. Fall in levels toward end of luteal phase can contribute to feelings of anxiety and irritability
uterine cycle
changes in the endometrium in response to the ovarian cycle
Cervical canal
communicates with - Vagina via external os - Uterine body via internal os
Meiosis II
completed (only if sperm penetrates oocyte
Primary oocytes
develop in primordial follicles begin meiosis; stall in prophase I
Endometriosis
growth of endometrial tissue outside the uterus
ovarian cycle
hormonal interactions between the hypothalamus, pituitary, and ovaries (HPG axis!)
Prolapse
ligaments supporting the uterus weaken, uterus sags down into vagina
estrogens
maintain bone density
cervix
narrow neck, or outlet; projects into vagina
corpus luteum
produces estrogen and progesterone
oogenesis
production of ovum
cervical glands
secrete mucus that blocks sperm entry except during midcycle
Oogonia
stem cells that produce primary oocytes by mitotic division
Fibroids
tumors that grow within or outside the uterus
Ovaries
two main functions of: - Release mature oocytes (ovulation) - Produce and secrete sex hormones
Breast cancer
• Usually arises from epithelial cells of smallest ducts; eventually metastasize • Risk factors include - Early onset of menstruation and late menopause - No pregnancies or first pregnancy late in life - No or short periods of breast feeding - Family history of breast cancer
