#1
Front (Question)

Which direction does the primitive streak FIRST develop in?

Back (Answer)

Anteriorly

#2
Front (Question)

Which tissues etc do the somites give rise to?

Back (Answer)

Cartilage and bone

#3
Front (Question)

Which direction does mesoderm segmentation occur in?

Back (Answer)

Anterior to posterior fashion

#4
Front (Question)

What is the tissue called before it forms somites?

Back (Answer)

Presomitic mesoderm

#5
Front (Question)

What is the clock and wavefront mechanism?

Back (Answer)

Clock ‘ticks’ in posterior presomitic mesoderm-> wave front passes thru psm until it hits boundary between somites and psm-> these cells receive a signal in the form of oscillating gene expression-> commits them to form a somite

#6
Front (Question)

What signalling is involved in boundary formation? And what do boundary cells do?

Back (Answer)

Notch signalling Boundary cells instruct anterior cells to form a boundary

#7
Front (Question)

Which 2 opposing gradients positions the determination front?

Back (Answer)

Retanoic acid FGD

#8
Front (Question)

Which 2 signals initiate the wave front?

Back (Answer)

C-hairy 1 Lunatic fringe

#9
Front (Question)

What does notch activation do?

Back (Answer)

Down regulates notch ligands (delta)

#10
Front (Question)

What is somitogenesis?

Back (Answer)

Epithelialisation of somites

#11
Front (Question)

When does somite formation occur in regards to FGF/WNT?

Back (Answer)

When FGF/Wnt falls below a threshold level
