In
drosophila, Physical forces drive invagination of the ventral furrow. Following
statements regarding to this process:
A. The cellularized blastoderm will begin
to activate higher levels of myosin in the cells at the ventral midline and
preferentially at their apical surface.
B. Epithelial adhesions paired with
differential activation of dynein and tissue geometry create mechanical
constraints that affect the orientation of actomyosin meshworks.
C. The A/P oriented arrays of myosin in the
cells at the ventral midline generate tension along the anterior-posterior
axis.
D. The combination of tissue geometry and
tension of these anterior-to-posterior meshworks cause the tissue to fold
outward at a right angle to the anterior-posterior axis, creating a long and
narrow ventral furrow.
