Chapter 16 Notes

Front 1

days 1-5 of the menstrual cycle

Back 1

functional layer of the endometrium is sloughed

bleeding occurs for 3-5 days

by day 5, growing ovarian follicles are producing more estrogen

Front 2

days 6-14 of the proliferative stage

Back 2

regeneration of functional layer of the endometrium

estrogen levels rise

ovulation occurs in the ovary at the end of this stage

Front 3

days 15-26 of the secretory stage

Back 3

levels of progesterone rise and increase the blood supply to the endometrium

endometrium increases in size and readies for implantation

Front 4

what do follicle cells produce

Back 4

estrogen

Front 5

estrogen causes what secondary sex characteristics

Back 5

enlargement of accessory organs

development of breasts

appearance of axillary and pubic hair

widening and lightening of the pelvis
