Reproductive System 1 Flashcards
Male gametes
Sperm
Female sex cells
Ova
Result of fertilization
Zygote
Male organs function
Produce, store, and introduce male sperm
Function of women’s reproductive system
Produce ova, receive sperm, permit fertilization and allows the ovums maturation
Reproductive or sex cells
Gametes
what is sometimes used to describe the dual urinary and reproductive function of the reproductive system
urogenital system
reproductive organs are classified as
essential or acessory
acessory organs in men
- A series of passagewaus or ducts that carry the sperm from the testes to the exterior
- Additional sex glands that procide secretions that protect and nurture sperm
- The external reproductive organs called the external genitals
mans gonads
testes
where are the testes located
scrotum
Why is the scrotum important
It allows that testes to be about one degree celsius cooler than the rest of the body.
each testes is surrounded by a membrane called
tunica albuginea
What does the tunica albuginea do
covers the testicle and then enters the glands to form the many septa that divide it into sections or lobules
secrete the male sex hormone
interstitial cells
cells lying near the septa that separate the lobules
interstital cells
male sex hormone
testosterone
each lobule consists of a narrow but long and coiled _____
seminiferous tubule
where do sperm develop
In the walls of the seminiferous tubule
sperm production is called
spermatogenesis
sperm stem cells
spermatogonia
hypothalamus released what hormone for both females and males that is significant for reproduction
gonadotropin releasing hormone (GnRH)
(GnRH) stimulates the release of what
follicle stimulating hormone and luteinizing hormone
speratogenium mitosis and cell division results in
speratogonium and primary spermatocyte
spermatocytes undergo what in order to form sperm>
specialized form of meiosis
daughter cells of primary spermatocytes
daughter spermatids
are among the most highly specialized and smallest cells in the body
spermatozoa
The nucleus of a sperm cell is coverd by what
an acrosome
what does acrosome do
it is a specialized structure containing enzymes that enable the sperm to break down the covering of the ovum and permit entry if contact occurs
Testosterone serves to:
1: Masculinization
2. Promotion ad maintenance of the development of the male accessory organs
3. Stimulation effect of protein anabolism
undescended testis
cryptorchidism
fist tube the sperm enters that is very coiled, in the scrotum, and approxiamately 6 M long
Epididymis
Where sperm mature and develop their ability to move or swim
epididymis
tube that permits sperm to exit the epididymis
vas deferens
the tubule after the vasdeferens joins the seminole vesicle
ejaculatory duct
what duct passes throught the substance of the prostate gland
ejaculatory duct
What permits sperm to enter into the urethra
ejaculatory duct
Mixture of sperm and fluid excreted by sex glands
Semen
Semen is the same as
Seminal fluid
What are the sex glands
Two seminal vesicles, one prostate glands, two bulbourethral glands
Contribute to about 60% of the seminal fluid
Seminal vesicles
Provides energy for highly motile sperm
Seminal vesicles secretions
Secretes yellowish, thick and rich in the sugar fructose
Seminal vesicles
Shaped like a doughnut and lies just below the bladder
Prostate gland
Secretes a thin, milk colored fluid that accounts for about 30% of semen
Prostate gland
Secretions activate the sperm and help them maintain their motility
Prostate gland
Releases preejaculate
Bulbourethral glands
Functions of the bulbourethral glands
1) neutralize any residue of sperm damaging acidic urine in the terminal urethra
2) lubricates the urethra to protect the sperm from friction damage during ejaculation
Organ that, we made stiff and direct by the filling of it spongy or tile tissue components of blood during sexual arousal, can answer and deposit sperm in the vagina during intercourse
Penis
Three separate columns of erectile tissue in the penises shaft
Corpus spongiosum, And 2 layers of corpus cavernosmu
Erectile tissue that directly surrounds the urethra
Corpus spongiosum
A sensitive part of the penis at the distal end of the shaft
Glans
A loose fitting read tractable color called blank that covers the glans
Foreskin or prepuce
Surgical removal of the foreskin
Circumcision
