The two layers of the endometrium
|
BASILAR LAYER: permanent , vascular but very thin
FUNCTIONAL LAYER: regenerated and lost during each menstrual cycle |
|
FUNCTIONAL LAYER of endometrium
|
Regenerated and lost during each menstrual cycle
Under influence of estrogen & progesterone from ovaries from ovaries, the growth of blood vessels preps it for embryo |
|
What does the endometrium form during pregnancy?
|
The maternal portion of the placenta
|
|
Phase of MENSTRUAL CYCLE in which each takes place:
1) Rupture of mature follicle 2) Loss of the endometrium 3) the corpus luteum develops 4) Several follicles begin to develop |
1) Follicular phase (2nd phase)
2) Menstrual phase (1st) 3) Luteal phase (3rd) -- or is it secretory phase?? |
|
Without ____ , the endometrium cannot be maintained.
|
Progesterone
|
|
What produces (menstrual cycle)
1. FSH 2. LH 3. Estrogen 4. Progesterone |
1. Anterior Pituitary
2. Anterior Pituitary 3. Ovarian follicle 4. Corpus Luteum |
|
MENSTRUAL CYCLE (28 day cycle)
Includes FSH, LH, Estrogen, Progesterone, and changes in the ovaries and endometrium. --- general outline of phases |
1. MENSTRUAL- loss of the endometrium
2. FOLLICULAR- several ov follicles develop; ovulation is the rupture of a mature follicle; blood vessels grow in he endometrium 3. LUTEAL- the ruptured follicle becomes the corpus luteum ; the endometrium continues to develop 4. If fertilization does not occur, decreased progesterone results in the loss of endometrium in menstruation. |
|
Endometrium
|
A specialized mucosa that varies in thickness and composition through the menstrual cycle. Covering the surface are ciliates cells interrupted at intervals by the offices of mucous glands
|
|
Thickness & appearance of endometrium during:
1. Menstrual phase 2. Postmenstrual phase 3. Proliferative phase 4. Secretory phase |
1. (days 1-5). <0.5 mm Thin echogenic line
2. (days 6-9) 1-2 mm Mostly anechoic 3. (days 10-13) 2-4 mm Slightly echogenic 4. (days 14-28) 5-7 mm Highly echogenic |
|
During the menstrual cycle, the endometrial lining is primarily estrogenic or more progestational?
|
Estrogenic
|
|
During ovulation, the balance shifts to that of a more estrogenic or more of a progestional state?
|
Progestational
|
|
Sonographically, how does the endometrium appear...
1). During menstrual cycle 2) Post ovulation to menses 3). from menses to ovulation (proliferative phase) |
1)
2) the entire endometrium is echogenic 3) thickened and hyperechoic at the periphery and the endometrial line is echogenic |
|
Endometrial thickness
1. Pre-Menopausal 2 Post-Menopausal 3. Post spontaneous Abortion |
1. 2-18 mm ... Varies with menstrual cycle
2. < 5 mm ... May be up to 8mm if on HRT 3. Less than or equal to 5 mm Thicker measurements post spontaneous abortion indicate retained products of conception |
