Flashcards in Mammalian Test #1 Deck (25):
1

Tbx and Pitx1

transcription factors resulting in Fgf10 expression in LPM over 5 somite domain

2

Fgf10

factor stimulating Apical Ectodermal Ridge (AER)

3

Fgf8

Expressed by AER, stimulates proliferation of LPM and Fgf8 formation (positive feedback limb bud formation)

4

Walk on plantar surface of foot

5

Digitigrade

Walk on digits

cursorial advantages

-feeding/foraging over long areas
-migrating
-can overtake prey/run from predators
