The Menstrual Cycle
The structure noted within the Graafian follicle containing the developing ovum is the:
Cumulus oophorus
Which hormone released by the ovary during the proliferative phase stimulates endometrial thickening?
Estrogen
which structure remains after the corpus luteum has regressed?
corpus albicans
which hormone maintains the corpus luteum during pregnancy?
hCG
The first menstrual cycle is termed:
menarche
what is the typical sonographic appearance of the endometrium during the secretory phase?
hyperchoic and thick
When the sonographic three line sign is present the functional layer of the endometrium typically appears:
hypoechoic
The periovulatory phase may also be referred to as the:
late proliferative phase
Which of the following could also be described as intermenstrual bleeding?
metrorrhagia
What structure produces hormones that directly act upon the endometrium to produce varying thicknesses and sonographic appearances?
ovary
When the ovary is in the luteal phase, the endometrium is in the:
secretory
The second phase of the endometrial cycle is the:
secretory phase
The arteries within the functional layer of the endometrium that are altered by the hormones of the ovary are shed with menstruation are the:
spiral arteries
The two hormones produced by the anterior pituitary gland that impact the menstrual cycle are:
LH and FSH
FSH is produced by the:
anterior pituitary gland
LH is the produced by
anterior pituitary gland
Painful and difficult menstruation is termed:
dysmenorrhea
An increase in the number of endometrial cells is termed:
endometrial hyperplasia
The first phase of the ovarian cycle is the:
follicular phase
The hormone produced by the trophoblastic cells of the early placenta is:
hCG
During which phase of the endometrial cycle would the endometrium yield the three-line sign?
late proliferative
Which of the following is said to be a common cause of DUB?
polycystic ovary syndrome
What is defined as frequent regular cycles but less than 21 days apart?
polymenorrhea
The corpus luteum primarily releases:
progesterone
What hormone maintains the thickness of the endometrium after ovulation?
progesterone
Which of the following hormones is released by the ovary during the second half of the menstrual cycle?
progesterone
The first phase of the endometrial cycle is the:
proliferative phase
The measurement of the endometrium during the early proliferative phase ranges from:
4 to 8 mm
A change in menstrual bleeding associated with lesions w/i the uterus relates to:
AUB
The temporary endocrine gland that results from the rupture of the Graafian follicle is the:
Corpus luteum
The hormone that surges at ovulation is:
LH
The second phase of the ovarian cycle is called the:
luteal phase
Ovulation typically occurs on day - of the menstrual cycle
14
The average menstrual cycle lasts:
28 days
The hormone produced by the hypothalamus that controls the release of the hormones for menstruation by the anterior pituitary gland is:
GnRH
The dominant follicle prior to ovulation is termed the:
Graafian follicle
what structure may be noted on the ovary just prior to ovulation ?
Graafian follicle
Ectopic endometrial tissue within the uterus that leads to AUB is termed:
Adenomyosis
The hormone of the pituitary gland that stimulates follicular development of the ovary is:
FSH
which of the following would not be a cause of AUB?
ovarian torsion
