THE MAIN PURPOSE OF THE REPRODUCTIVE SYSTEM FOR MEN AND WOMEN IS
TO?
Produce offspring
WHAT ARE GAMETES(SEX CELLS)
They are produced by men in the testes and women in the ovaries.
WHAT IS THE GAMETE FOR MEN?
Sperm
WHAT IS THE GAMETE FOR WOMEN?
Ova(egg)
HOW MUCH GENETIC MATERIAL DOES A GAMETE CONTAIN TO PRODUCE A
HUMAN BABY?
One half
,WHAT IS THE MANS CONTRIBUTION TO CHILDBIRTH?
His genetic material not only determines the sex of the unborn child, but also
influences numerous other inherited traits. The reproductive anatomy of men consist
of external and internal reproductive organs. The purpose of the reproductive tract of
men is to allow for sexual intimacy and reproduction of offspring and provide a
conduit for urinary elimination.
WHAT IS THE SCROTOM?
An external sac that houses the testes.
WHAT ARE THE MAIN FUNCTIONS OF THE SCROTOM?
To protect the testes from trauma and to regulate the temperature within the testes.
WHAT IS THE IDEAL TEMPERATURE WITHIN THE SCROTUM?
96 F just slightly lower then normal body temperature.
WHAT TWO IMPORTANT FUNCTIONS DO THE TESTES SERVE?
Production of androgens (sex hormones for men) and formation and maturation of
sperm
THE PITUITARY GLAND GOVERNS REPRODUCTIVE HORMONE PRODUCTION AND
FUNCTION
Luteinizing Hormone(women)
Interstitial Cell Stimulating Hormone(men)
WHAT ARE SEMINIFEROUS TUBULES?
, Tiny coils of tissue in which production of sperm occur
SPERMATOGENESIS
production of sperm
WHAT SURROUNDS THE SEMINIFEROUS TUBULES AND PRODUCE THE ANDROGEN
TESTOSTERONE, WHICH IS NECESSARY FOR MATURATION OF SPERM?
Interstitial Cells
EPIDIDYMIS
An intricate network of coiled ducts on the posterior portion of each testis. It is here
where the sperm matures.
VAS DEFERENS
The muscle tube in which sperm begin their journey out of the man's body.
WHAT HAPPENS IN THE SPERMATIC CORD AND VAS DEFERENS CONTAINED
WITHIN IT WHEN IT LEADS INTO THE ABDOMINAL CAVITY?
It Leads i to the abdominal cavity through the inguinal canal, arches over the urinary
bladder, and then curves downward on the posterior side of the bladder. It is at this
point that the vas deferens joins with the ejaculatory duct. The paired ejaculatory
ducts then connect with the urethra, which transports the sperm out of the man's
penis during ejaculation.
ANOTHER HORMONE THAT MAKES THE LH BE SECRETED FROM THE ANTERIOR
PITUITARY IS?
GNRH (Gondotropic Releasing Hormone)
