Male Reproductuve Anatomy Flashcards
Follicle Stimulating Hormone(APG
Target- seminiferous tubules
Function- sperm produced
Luteinizing Hormone(APG)
target- interstitial cells
Function- testosterone produced
Inhibin(Sertoli Cell)
Targets- Hypothalamus
Function- less GnRH,less, FSH and less LH
Flagella
Sperm motility (propeller)
Midpiece (mitochondria)
Energy generator (consumes fructose)
Nucleus
Contains 23 chromosomes
Acrosome
Cap that contains enzymes to break down egg layers
Enzyme
Break egg shell, called Hyalrilidase
Sertoli Cells(nurse)
Produce fructose & Inhibin
Destroy mutated/damaged sperm
Seminiferous tubules
Produce sperm
Sperm
Male gamete
Interstitial cells
Produce testosterone
Primary spermatocytes
Become sperm
Testes
Produce sperm, testosterone, and Inhibin
Vas Deferens
Tube that leads sperm into body for ejaculation
Epididymis
Region of testes where sperm matures & learns to swim
Scrotum
Muscular sac to house the testes outside of body
Urethra
Tube that transports both urine & semen
Penis
Delivers sperm into female
Glans Penis
Nerve endings on penis end (sensation)
Prepuce
Foreskin to cover penis end
Seminal Vesicles
Base of bladder where Vas deferens enters the Prostate
Secreted fructose(food for sperm), Prostaglandins(hormone which allows the female cervix to allow Sperm in) and sodium bicarbonate(neutralize the acidic vagina)
Prostate Gland
Squeeze & Push, force behind ejaculation
Secretes- Sodium Bicarbonate(neutralize acidic vagina), Milky fluid (to aid sperm motility)
Cowpers Gland
Secretes- clear Mucus aka pre ejaculation which cleans and lubricates the acidic urethra. Cleans urethra so no sperms get damaged
