Hormonal Control of Menstral Cycle

What is a hormone? chemicals that are produced in one part of the body and affect another
What system is responsible for the production of hormones? Glands
Sketch a picture of the female reproductive system. Include the oviduct, ovaries, uterus, cervix and vagina.
Where does the embryo undergo most of its development? uterus
What is another name for the fallopian tube? oviduct
Where does fertilization take place? oviduct
What is ovulation? the mature ovum contained in the follicle bursts out and migrates to the oviduct
What is the follicle converted to? corpus lethum
What happens during the flow phase? hormone production by the ovaries ceases and the uterine lining sloughs off
What happens during the follicular phase? developing follicle enlarges and produces a hormone which causes the uterine lining to thiken.
What happens during the luteal phase? a hormone from the pituitary converts the follicle to corpus lethum
What happens to the uterine lining during the first phase? breaks down and bleeding occurs
What are the four hormones that control the menstrual cycle? FSH, LH, progesterone, estrogen
As FSH increases in concentration in the blood , the follicle is? increasing
When the follicle ruptures it releases what? egg

What do you call a couple using the rhythm method? parents
What is menopause? when you stop having your period What causes it? loss of LH
When does fertilization occur? when the egg and sperm meet
When is a zygote formed? during fertilization
What is a placenta? the tree of life, where charlie grew

Male and Female Reproductive System

What are the two functions of the testes? production of sperm cells, and secretion of endocrine substance
What is the name of the structure where the testes are located? scrotum
Why are the testes located outside the body? by keeping them outside the body the sperm functions better
