Flashcards in Ch 4- The Reproductive System Deck (88):
New gene combinations
Testes secrete hormones...
That help shape the body as well as mental attitudes
-Cryptochildish develpos if the testes do not descend
Surface of the testes where sperm mature and are stored prior to ejaculation.
-2 degrees below body
-cremasteric and dartos muscles: contract in responses to temp
-arteries and veins
Tubes that transport the sperm during ejaculation
The cutting of the vas Deferens is a male birth control procedure.
-produced at a rate of millions per day
- sperm + additives = semen
-live 2 days in the female tract
Sertoli cell : FSH ~make sperm
Interstitial cells : LH
Conducts the sperm out into the vagina
Help make up the sperm
Also a buffer to neutralize what is in the urethra and vagina
Acts like a billow during
Neutralize the acidic conditions inside the vagina
3 glands that help with ejaculation
Why additives need to be added to the sperm
1) provide nutrients
3) neutralize the acidity
Primary sex organ
Gonads / testes- that produce sperm
Secondary sex ograns
Every thing else.
Epididymis, vas Deferens, seminal vesicles, prostate gland, Cowper's gland and penis
Inflammation of the glands penis
Removal of all or part of the prepuce
Inflammation of the testes
Inflammation of he prostate gland
Removal of a short section of the van Deferens (both) to produce sterility
Inability for a make to have an erection
Produce sperm cells
-contain 300000 follicles at birth
-decline to about 12000 at puberty
-only about 400 of these will be ovulated
-Finger like extensions off the top of the Fallopian tube
-sweep the egg into the opening of the Fallopian tube
Sperm + egg
-muscular organ about the size of a fist
Located inside the vagina
- secretes a fluid that lubricates the vagina to assist in copulation
Protective pad during colitis and contains the pubic hair
-Pubic hair is present
-other lubricating glands
Folds of skim protect the opening of the vagina
- no pubic hair or sweat glands
-folds also protect the opening of the vagina
Erectile tissue as well as a protective structure
-forms a plug during pregnancy
-2nd most common location for cancer in females
-fatty deposits & glands that secrete milk through a series of tubes to the nipple
Production of milk requires
Oxytocin is necessary for milk let down
Ovulation, fertilization, implantation, HCG, endometrium, estrogen, progesterone, FSH, LH, Fallopian tube, distal 1/3, fimbrae, ovum, follicle, corpus luteum, sperm, vagina, cervix, zygote, blastocyst, placenta, embryo, acrosome, uterus
The primary sex organs of the female
Ovaries-----which produce the ova (egg) and store till ovulation
Secondary sex organs are
Suppression or absenc of menstruation
Inflammation of the bartholins gland
Extraction of fetus through the abdominal wall
The 1st fluid secreted by the mammary glands.
Yellow, nutrients, anti body's
Removal of the vagina
due to obstructions, inflammations, and certain diseases
Implantation and development of the fetus outside the uterine wall
Incision(cut) in the vulva to help in the delivery of the baby as well as prevention of lacerations (rip)
Cut instead or rip
Normal length of pregnancy
Removal of the uterus
Removal of the ovaries
Swab cervix and endometrium for cancer
Birth of child
1st fetal movement
Jell injected into the Fallopian tubes
The beginning of menstuation and ovulation
Inhibit sensory nerve transmission during labour
4 phase of Menstrual cycle
Flow or menstrual
Flow or menstrual phase
Endometrium is shed
Ovarian follicles begin to develop
The building up of the endometrium
Estrogen received by the uterus
Day 7 to day 14
Ova burst from the ovary and is swept into the oviduct by fimbrae
After the ovary has released
Progesterone is maintaining the uterus lining
Day 15 to day 28
Tearing the lining go the uterus
Developing scar tissues
How many sperm reach the oviducts and the egg?
Only a few hundred, even tho there is between 150 and 300 million sperm cells ejaculated
The journey the zygote/blastocyst takes from the Fallopian tubes to the uterus takes.....
When the blastocyst becomes attached to the wall of the endometrium....
Amnion and chorion are formed
-the chorion develops into the placenta
A full term gestation period is ____ days from the point of fertilization.
Or counting ____ days from the start of the last menstrual cycle.
