Term Definition
fission separation of an organism into two new cells
budding splitting off of new individuals from existing ones
fragmentation single parent breaks into parts that regenerate into new individuals
parthenogenesis development of an egg without fertilization
seminiferous tubules site of sperm formation in testes
leydig cells scattered among the seminiferous tubules and produce testosterone
epididymis tube in the testes where sperm gain mobility
vas deferens duct that carries sperm during ejaclution from epididymis to penis
seminal vesicles secrete mucus, fructose sugar and prostaglandin
ovaries site where meiosis occurs and where secondary oocyte forms prior to birth
oviducts (fallopian tubes) where fertilization occurs
uterus where the blastocyst will implant and the embryo develop
endometrium lining of the uterus that thicks monthly in preparation for implantatin of the blastocyst
follicular phase growth of several follicles in the ovaries that secrete increasing amount of estrogen in response to FSH
ovulation secondary oocyte ruptures out of the ovaries in response to luteinizing hormone
luteal phase corpus luteum forms from the follice left behind and secretes estrogen and progesterone which thicken endometrium of uterus
menstruation monthly shedding of the lining of the uterus when fertilization does not occur
spermatogenesis process of sperm production; each produces 4 spermatids
spermatogonium cell first product in sperm production, divides by mitosis two.
primary spermatocytes produced from spermatogonium cell and undergoes meiosis to produce two secondary spermatocytes
spermatids formed from two secondary spermatocytes that undergo meiosis II to produce 4 of them
acrosome head of the sperm that releases hydrolytic enzymes allowing it to enter the egg
vitelline membrane membrane on the egg that contains specific recognition sites allowing only sperm from the same species to fertilize the egg
cortical reaction changing of the vitelline membrane into a hard fertilization envelope that further resists the entry of other sperm
cortical granules cause changes in the vitelline membrane that harden it; activated by signal transduction pathway that increases the amount of Ca++ in the egg
cleavage rapid mitotic division of a zygote that occurs immediately after fertilization
gastrulation process that involves rearrangement of the blastula and begins with the formatino of the blastopore
gastrula second phase of early embryonic development that results in formation of blastopore
mesoglea a noncellular embryonic layer found in some primitive animals
organogenesis process by which cells continue to differentiate
vegetal pole yolky portion of egg
gray crescent appears after fertilization of frog egg and is located at the point of entry of the sperm
archentron primitive gut in embryo development
involution process by which cells at the dorsal lip of the blastopore begin to stream over the doral lip and into the blastopore
notochord first organs that begin to form in chordates and are the skeletal rod characterisc
neural tube becomes central nervous system
blastodisc site of embryonic development in bird's eggs
primitive streak takes the place of the gray crescent in bird eggs
amnion encloses the embryo in protective amniotic fluid
chorion lies under the shell and allows for diffusion of respiratory gases between the outside and the growing embryo
allantois analogous to placenta in humans
hans spemann scientist that demonstrated the importance of the cytoplasm associated with the gray crescent in the normal development of the animal
embryonic induction ability of one group of embryonic cells to influence the development of another group
primary organizer name given to the dorsal lip by Spemann because it plays a crucial role in development
