reproductive system Flashcards
where are testis located
outside the abdominal cavity within the scrotum
why do testis descend out of body during fetal development
the temp is lower which is ideal for viable sperm production
what are the testis made of
sections called lobules with tightly coiled seminiferuous tubules
what do lobules contain
tightly coiled seminiferous tubules
what are seminiferous tubules
where sperm is made
what is the production of sperm called
spermatogenesis
what is the spermatogenesis process
starts with undifferentiated cells then splits into another cell and spermatogonia then secondary spermatocytes then two spermatids and then two spermatozoa
what are the parts of the sperm
head, middle piece acrosome and tail
what does the tail do
is flagella for movement ( has 9+2 pattern of microtubules)
what does head of sperm
contains nucleus
what does the middle piece do
has the mitochondria for producing energy for flagella
what does the acrosome do
has enzymes that are for penetrating outer wall of egg
what are interstitial cells
cells that produce male hormone testosterone
