1 through 5
With menarche what may be influenced?
Environment and diet
Primary amenorrhea may be caused by what
congenital abnormalities or congenital obstruction such as imperforate hymen

Endocrinologic abnormalities or pregnancy, secondary amenorrhea that is not associated with pregnancy is characteristically diagnosed and the postmenarcheal woman who has had at least 12 months without a menstrual cycle
What is the responsibility of the hypothalamus?
Regulate and release of hormones by the anterior pituitary gland the hypothalamus achieves this function by releasing its own hormone gonadotropin-releasing hormone which in turn stimulates the release of hormones by the anterior pituitary gland
The pituitary gland AKA? Located where? Responsible for?
Master gland, endocrine gland located within the brain that consists of an anterior and posterior lobe, anterior lobe responsible for the release of two hormones follicle-stimulating hormone and luteinizing hormone, FSH causes the development of multiple follicles in the ovaries, LH surges around day 14 of the menstrual cycle which results in ovulation
The ovary produces what two hormones during the menstrual cycle?
Estrogen and progesterone
Estrogen is produced throughout the menstrual cycle it is initially produced by what?
Theca internal cells of the secondary follicles during the first part of the menstrual cycle, during this phase estrogen initiates the proliferation and thickness of the endometrium by encouraging the growth and expansion of spiral arteries and glands within the functional layer of the endometrium, oxygen has many other important functions, regeneration of the endometrium after Menses and induction of salt and water retention, simulates contractile emotions within the uterine myometrium and Fallopian tubes, during second half dimensional cycle following ovulation progesterone is produced by the corpus luteum of the ovary, progesterone is responsible for maintaining the thickness of the endometrium and inducing its secretory activity as it is prepared for implantation

FSH
Around what day is LH produced by the anterior pituitary gland which stimulates ovulation at which time the graafian follicle which is grown ruptures and expels a small amount of fluid and the ovum into the peritoneal?
14
The second phase of the ovarian cycle days 15 to 28 is termed what phase?
Luteal
The basal layer is slightly altered during the menstrual cycle and consist of what?
Dense cellular stroma
The endometrial cycle consists of what two phases?
