Reproductive System
Events of female Hormones
Follicle phase
stimulates the growth of the egg about 15-20 eggs in ovaries
ovulation
release of an egg after it is released, it travels down the fallopian tube, where fertillization by a sperm
luteal phase
it starts before eriod statrs the loning of your uterus normally gets thickeer to prepare for possible pregnancy
Mensrtration
decline of estrogen and progesterone cause the spiral arteries to constrict
proliferative phase
estrogen causes the uterus to grow or proliferate,during this thing ,as they mature
secreatory phase
the relaease od=f a mature egg from the ovary
Hormones of reproductive system
leutinizing hormone (LH)
anterior pituitary hormone that stimulates the production of testosterone
gonadotropin releasing hormone (GnRH
hypothalamus hormone that triggers the anterior pituitary to release FSH and LH
estrogen
primary female sex hormone released by follicle; responsible for thickening of uterine wall
progesterone
second female sex hormone produced by corpus luteum
follicle stimulating hormone (FSH)
hormone responsible development of primary follicle into secondary follicle
Anatomy of male & female reproductive system
Female
Ovaries
produces oocytes and production of hormones
Endometrium
inner most linning layer of the uterus
Cervix
allow flow of menstrual blood from uterus to the vagina
Uterus
hollow organ houses the developing embryo and fetus until birth; site of implantation
Vagina
A muscular, elastic passageway that extends from the uterus to the outside of the body; birth canal or receptacle for penis during intercourse
Uterine tube
also known as oviducts or Fallopian tubes, are the female structures that transport the ova from the ovary to the uterus; site of fertilzation
lobule of mammary gland
A breast lobule is a gland that makes milk. Enlarge. Anatomy of the female breas
lactiferous ducts
milk ducts which carry milk from the mammary glands to the nipple
The 15-24 milk ducts that collect milk from ductules and carry it to the nipple. If the alveoli are the "grapes" these structures would be the "stems"
milk ducts which carry milk from the mammary glands to the nipple
The 15-24 milk ducts that collect milk from ductules and carry it to the nipple. If the alveoli are the "grapes" these structures would be the "stems"
nipple
the protuberance of a mammary gland upon which in the female the lactiferous ducts open and from which milk is drawn.
areola
a small circular area, in particular the ring of pigmented skin surrounding a nipple.
round ligament
connects lateral uterus to lateral pelvic wall obliquely
ovarian ligament
anchors the ovary medially to the uterus
suspensory ligament
anchors the ovaries to the lateral walls of the pelvis.
broad ligament
The ligament extending from the lateral margins of the uterus to the pelvic wall; keeps the uterus centrally placed and provides stability within the pelvic cavity
Male
Testes
primary male sex organs
sperm
male gametes
seminiferous tubules
where sperm are produced in the testes
epididymis
the first part of the male duct system; site of sperm maturation; temporary storage site for immature sperm
urethra
part of the male duct system that both sperm and urine travel through out of the body
urethra
seminal vesicles
produce thick, yellow fluid (60% of semen) that nourishes the sperm and helps activate it
prostate
a doughnut shaped gland that wraps around the urethra and secretes a milky fluid that activates sperm
bulbourethral glands
produce a thick, clear mucus that cleanses the urethra of any traces of acidic urine before ejaculation and acts as a lubricant for sexual intercourse
semen
mixture of sperm and accessory gland secretions
Scrotum
a sac of skin that surrounds the testes
penis
organ designed to deliver sperm into the female reproductive tract
erectile tissue
the spongy tissue inside the penis that fills with blood during an erection
spermatogenesis
production of spermatids
spermatogonia
male reproductive stem cell; divides rapidly at birth
primary spermatocyte
the cell that undergoes meiosis to form the spermatid
spermatid
immature sperm cell
acrosome
covering over the head of the sperm cell that contains enzymes to help the sperm penetrate through the capsule that surrounds the ovum
vas deferens
another term for the ductus deferens
Major Functions
Male
to produce and dismantle large quantity of male gamete
Female
prepare for implantation and prepares for developing during pregnancy
