A spike in the release of LH causes this to happen in females
Ovulatory phase.
What are the 4 phases of the menstrual cycle?
Flow phase
Follicular phase
Ovulation
Luteal phase
Structure made of the follicle cells of the ovary after ovulation. that secretes estrogen and progesterone
Corpus lutuem
How many follicles develop during each female cycle?
only 1 reaches maturity
An increase in estrogen mid cycle causes
AN INCREASE IN LUTEINIZING HORMONE (+ FEEDBACK)
What turns off GnRH production in males? In females?
INCREASED LEVELS OF TESTOSTERONE AND ESTROGEN (NEGATIVE FEEDBACK LOOP)
Reproductive hormone released from the hypothalamus in males and females?
GnRH (Gonadotropin-releasing hormone) GnRH stimulates your pituitary gland to make and release follicle-stimulating hormone and luteinizing hormone.
Structures in the ovary that contain the egg; secrete estrogen.
Follicles
The lining of the uterus that receives and nourishes the embryo
endometrium
The female gonads that produce estrogen and progesterone.
ovaries

oviducts
A muscular band that must dilate for the baby to pass out of the uterus
cervix
The muscular birth canal
Vagina
Contains the urethra; deposits sperm into the vagina during ejaculation.
Penis
Testes are located here due to the cooler temperature.
Scrotum
The ends of the oviducts that sweep the egg inside
fimbria
Gland that contributes mucus-rich fluid to cleanse urethra of acid.
cowpers gland
Gland that contributes buffers to protect sperm from vaginal acids
Prostate Gland
Gland that contributes fructose and prostaglandin to seminal fluid.
seminal vesicle
Coiled tubes in the testes that produce immature sperm cells
Seminiferous tubules
The tube that carries sperm to the urethra
vas deferens
The male gonads which produce hormones and sperm.
Testes
Also known as the womb; baby develops here.
Uterus
Sperm cells are stored and mature here on top of the testes.
