Animal Reproduction And Development

Front 1

gametogenesis

Back 1

oogenesis+spermatogenesis

Front 2

human chorionic gonadotropin (hCG)

Back 2

implanted embryo secretes to produce estrogen and progesterone to maintain the endometrium. pregnancy tests check for this

Front 3

luteal phase

Back 3

3rd and last phase of ovarian cycle. secretion of estrogen and progesterone from corpus luteum after ovulation

Front 4

gray crescent

Back 4

in a frog egg, each individual cell could develop into a normal frog only if it contained a portion of this

Front 5

morphogen

Back 5

proteins whose asymmetrical distribution in the cytoplasm of the oocyte determines the anterior/posterior and dorsal/ventral axes of the cell. Later acts as transcription factors

Front 6

homeotic genes

Back 6

master genes that specify the developmental patterns of groups of cells.

Front 7

homeobox

Back 7

180 nucleotide sequence found in all homeotic genes

Front 8

hox genes

Back 8

genes that contain the homeobox and direct the development if a specific body part. codes for transcription factors that control gene expression

Front 9

ovarian cycle

Back 9

follicular phase -> ovulation -> luteal phase

Front 10

acrosome

Back 10

contains enzymes that are used to transverse the outer coating of the egg

Hint 10

Front 11

epididymis

Back 11

where sperms become motile and are stored prior to ejaculation

Front 12

prostate gland

Back 12

produces a thin, slightly alkaline fluid that helps maintain sperm motility and counteract the acidity of the female reproductive tract

Hint 12

Front 13

seminal vesicle

Back 13

secretes a protein and sugar rich fluid that makes up most of the semen and provides energy for sperm motility

Hint 13

Front 14

bulbourethral gland

Back 14

produce a clear fluid that lubricates the urethra for passage of sperm

Hint 14

Front 15

vulva

Back 15

female external genitalia
