hormonal cycle and ovarian cycle are related
H derived from growing follicle in ovary
growing follicle produces hormones
ovulation = the big spike in LH
estrogen v progesterone graph
thickness of uterus, needs strogen as primer and progesterone increases the endometrium of the uterus
estrogen causes synthesis of prog receptors, no estrogen = no prog
estrogen has proliferatice effect
ovarian cycle, primary follicles grow under FSH (FSH causes them to grow)
LH causes ovulation itself
LH then causes glutimization of corpus lucium that remains in the ____
corpus ludium produces prog, req’d fo ruterine lining for pregnancy,
no progesterone = corpus involutes and creates scar tissue
follicles all present at birth, set at fetal growth, grow in response to FSH
inc in granulosa cells, thecal cells
hostilogical prep of oocyte image
folliculum epithelium is the granular cell
thecal cells outside of granulosa cells (internal and external types)
thecal cells are making steroids
LH stimulates estrogen production from thecal cells
FSH stimulates granulosa cells and LH stimulates thecal cells*** to make hormone
