(34 cards)
What is the function of the male reproductive system?
To produce gametes for propagation and hormones for male sex characteristics
What spermatogenesis?
production of sperm via meiosis
What are the two rounds of cell division that turn a diploid into a haploid cell?
Meiosis
Does DNA replicate again after meiosis I?
No
When does spermatogenesis begin?
at puberty and continues throughout a man’s lifetime
What are the two parts of the sperm head?
acrosome and nucleus
What part of the sperm contains enzymes required for fertilization, as the sperm penetrates the egg?
Acrosome
What part of the sperm contains the father’s DNA?
the Nucleus
What part of the sperm contains mitochondria to provide ATP that fuels the flagella?
Midpiece
What is the part of the sperm that is made of a whip like flagella that gives the sperm motility?
the Tail
Where is the sperm produced?
Testes
What is the double membrane that covers the testes?
deep tunica albuginea and tunic vaginalis
Where does spermatogenesis specifically occur?
seminiferous tubules
How does sperm leave the testes?
efferent ductules
Where does immature sperm do?
rete testes
Where do the efferent ductules lead to?
The epididymis (head body and tail where the sperm become motile)
Where does the epididymis lead to?
the vas deferens
Where is the vas deferens enclosed within?
The spermatic cord
What empties secretions into the ejaculatory duct?
Seminal vesicles
What stimulates uterine contraction and propulsion of sperm?
Prostaglandins
What is used to make ATP?
Fructose
Where does the ejaculatory duct lead to?
the prostatic urethra
What gland contributes to seminal fluid by providing alkaline fluid?
Prostate gland
What eventually becomes the membranous urethra?
Prostatic urethra
