Reproductive system Flashcards
composition of males testes
sperm
composition of females ovaries
eggs (ova)
different modes of reproduction in insects
sexual;
asexual;
sexual and asexual
sac like tubes where sperms are produced
follicles
a group of germ cell at the distal end of each follicle
spermatogonia
susunod sa spermatogonia;
under go meiosis (4 spermatids - mature spematozoa)
spermatocytes
where mature sperm form the testes pass out
vasa efferentia
where mature sperm collects
seminal vesicle
form a single ejaculatory duct
vasa defferentia
where sperm passes out of the body
ejaculatory duct
male copulatory organ
aedeagus
Pairs of secretory glands that are connected to the system thru short ducts;
In PERIPLANETA forms dense brunches of tubules called the “mushroom gland of Huxley”;
Manufacture seminal fluid and spermatophores
Accessory glands
sustains and nourishes the mature sperm
seminal fluid
proteinaceous pouch-like structure that encase the sperm
spermatophores
Swells with developing eggs;
Where eggs are actually produced
Pair of ovaries / ovaries
Germ cells near end of each ovariole;
Increase in size to form oocytes
Oogonia
susunod sa oogonia;
produced within each ovariole during active oogenesis;
under go meiosis (1 egg and 3 polar bodies)
oocytes
base of ovariole
calyx
common oviduct opening into a genital chamber
Bursa copulatrix
supply lubricants in the female reproductive organ;
connected by small ducts to common oviduct;
secretes chorion
female accessory glands
protein rich egg shell that surrounds the egg
chorion
male deposits spermatophore in bursa copulatrix
copulation
movement that forces spermatophore in the spermatheca
peristaltic contraction
pouch like for storage of sperm
spermatheca
