Occurrence depends on overall health and diet
Menarche,
12
__________ is the end of a woman’s reproductive phase, commonly occurs between ages __ and __
Menopause
45 and 55
Age of menopause is largely the result of __________
genetics
Menstrual cycle can be divided into 3 phases:
- __________ phase
- proliferative / ________ phase (estrogen)
- secretory / _______ phase phase (progesterone)
- menstrual
- follicular
- luteal
Menstrual cycle can be divided into 3 phases:
- menstrual phase
- proliferative / follicular phase (estrogen)
- secretory/luteal phase (progesterone)
Physiological changes during menstrual cycle can be observed at three different levels:
- ne____docrine level
- ov___s
- u___s
- neuroendocrine
- ovaries
- uterus
Physiological changes during menstrual cycle can be observed at three different levels:
- neuroendocrine
- ovaries
- uterus
FOLLICULAR PHASE
The rise of _______1._____ (FSH) during the first days of the cycle, stimulate several ovarian follicles
The follicle that reaches maturity is called a _______ follicle
The follicles secrete ________ , which thickens the new functional layer of endometrium in the uterus
Estrogen also stimulates crypts in the cervix to produce fertile __________ _______
At the end of this phase _________ occur
LH is necessary for follicular growth and ovulation.
- Follicle Stimulating Hormone (FSH)
- Graafian
- estrogen
- cervical mucus
- ovulation
In the Follicular Phase there is an increase in _____________ (FSH)
Follicle Stimulating Hormone
The follicle that reaches maturity is known as _____________
Graafian Follicle
Estrogen can be secreted by:
- The ______ Follicle (second)
- ____ Luteum
- Ovarian
2. Corpus
Estrogen can be secreted by:
- The Ovarian Follicle (second)
2. Corpus Luteum
___________ LH is necessary for follicular growth and ovulation.
luteinizing hormone
OVULATION
During the follicular phase, estrogen ______1___ production of luteinizing hormone (LH)
When the ovum has nearly matured, estrogen ___2_____ production of LH (positive feedback loop)
The release of LH causes the fully developed follicle to release its ____3____ oocyte
After being released from the ovary, the ovum is swept into the ________ tube
- suppresses
- stimulate
- secondary
- fallopian
luteinizing Hormone is ______1_____ in the Follicular phase
while
luteinizing Hormone is ______2______ on the Ovulation Phase
- Suppressed
2. Stimulated
LUTEAL PHASE
______1______ is a solid body formed in an ovary after the ovum has been released into the fallopian tube
Produces significant amounts of progesterone, which make ______2______ receptive to implantation of the blastocyst
High levels of Estrogen and Progesterone _____3_____ production of FSH and LH
Low levels of progesterone trigger menstruation and the beginning of the next cycle
- Corpus luteum
- endometrium
- suppress
High levels of of Estrogen and Progesterone Suppress production of ____________ FSH and ____________ LH
Follicle Stimulating Hormone and luteinizing hormone
___________ is a solid body formed in an ovary after the ovum has been released into the fallopian tube
Corpus luteum
progesterone aid to :
- Maintain the __________ layer of the uterus
and
2, makes the endometrium layer receptive to __________ of the blastocyst
- endometrium
2. implantation
Low levels of _________ trigger menstruation and the beginning of the next cycle
Nb: this is because progesterone maintains the layer of the uterus thus low levels of it means the endometrium degrades and causing discharge of blood
progesterone
Nb: this is because progesterone maintains the layer of the uterus thus low levels of it means the endometrium degrades and causing discharge of blood
Menstruation lasts __ days
3-5 days
