7
Q

an anatomic structure on the surface of the ovary, consisting of a spheroid of yellowish tissue that grows within the ruptured ovarian follicle after ovulation; acts as a short-lived endocrine organ that secretes progesterone to maintain the decidual layer of the endometrium should conception occur

A

corpus luteum

8
Q

pain associated with menstruation

A

dysmenorrhea

9
Q

a steroidal hormone secreted by the theca interna and granulosa cells of the ovarian follicle that stimulates the development of female reproductive structures and secondary sexual characteristics; promotes the growth of endometrial tissue during the proliferative phase of the menstrual cycle

A

estrogen

10
Q

portion of the pelvis found above the brim; that portion of the abdominal cavity cradled by the iliac fossae; also called the greater or major pelvis

A

false pelvis

11
Q

a hormone secreted by the anterior pituitary gland that stimulates the growth and maturation of graafian follicles in the ovary

A

follicle-stimulating hormone (FSH)

12
Q

a hormonal substance that stimulates the function of the testes and the ovaries; in the female, FSH and LH are gonadotropins

A

gonadotropin

13
Q

a hormone secreted by the hypothalamus that stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the anterior pituitary gland

A

gonadotropin-releasing hormone (GnRH)

14
Q

paired triangular, flat muscles that cover the inner curved surface of the iliac fossae; they arise from the iliac fossae and join the psoas major muscles to form the lateral walls of the pelvis

A

iliacus muscles

15
Q

a bony ridge on the inner surface of the ilium and pubic bones that divides the true and false pelvis; also called the pelvic brim or linea terminalis

A

iliopectineal line

16
Q

one of two muscles of the pelvic diaphragm that stretch across the floor of the pelvic cavity like a hammock, supporting the pelvic organs and surrounding the urethra, vagina, and rectum; a broad, thin muscle that consists of the pubococcygeus, iliococcygeus, and puborectalis

A

levator ani

17
Q

a hormone secreted by the anterior pituitary gland that stimulates ovulation and then induces luteinization of the ruptured follicle to form the corpus luteum

A

luteinizing hormone (LH)

18
Q

the onset of menstruation and the commencement of cyclic menstrual function; usually occurs between 11 and 13 years of age

A

menarche

19
Q

the cessation of menstruation

A

menopause

20
Q

abnormally heavy or long periods

A

menorrhagia

21
Q

the periodic flow of blood and cellular debris that occurs during menstruation

A

menses

22
Q

mesosalpinx

A

the upper portion of the broad ligament that encloses the fallopian tubes

23
Q

the upper portion of the broad ligament that encloses the fallopian tubes

A

mesosalpinx

24
Q

the posterior portion of the broad ligament that is drawn out to enclose and hold the ovary in place

A

mesovarium

25
Q

a triangular sheet of muscle that arises from the anterolateral pelvic wall and surrounds the obturator foramen, passes through the lesser sciatic foramen and inserts into the medial aspect of the greater trochanter of the femur, and serves to rotate and abduct the thigh

A

obturator internus muscle

26
Q

abnormally light menstrual periods

A

oligomenorrhea

27
Q

an incompletely developed or immature ovum

A

oocyte

28
Q

a paired ligament that extends from the inferior/medial pole of the ovary to the uterine cornua; also called the utero-ovarian ligament

A

ovarian ligament

29
Q

the female egg; a secondary oocyte released from the ovary at ovulation

A

ovum

30
Q

a serous membrane enveloping the uterus; also called the serosa

A

perimetrium

31
Q

a flat, pyramidal muscle arising from the anterior sacrum, passing through the greater sciatic notch to insert into the superior aspect of the greater trochanter of the femur; serves to rotate and abduct the thigh

A

piriformis muscle

32
Q

an abnormally frequent recurrence of the menstrual cycle; a menstrual cycle of less than 21 days

A

polymenorrhea

33
Q

time period in young girls before the onset of menstruation

A

premenarche

34
Q

a steroidal hormone produced by the corpus luteum that helps prepare and maintain the endometrium for the arrival and implantation of an embryo

A

progesterone

35
Q

paired muscles that originate at the transverse process of the lumbar vertebrae and extend inferiorly through the false pelvis on the pelvic sidewall, where they unite with the iliacus muscle to form the iliopsoas muscle before inserting into the lesser trochanter of the femur; serves to flex the thigh toward the pelvis
