Green lumber would contract, pulling away from the mortar and leaving air gaps.
With the tip acting as an anchor, the longitudinal muscles then contract, pulling the body down to the anchored foot.
Platelets play an important role in the formation of a blood clot by aggregating to block a cut blood vessel and provide a surface on which strands of fibrin form an organized clot, by contracting to pull the fibrin strands together to make the clot firm and permanent, and, perhaps most important, by providing or mediating a series of clotting factors necessary to the formation of the clot.
We discovered that whereas single cells generate tension by contracting and pulling on the matrix, the contraction of multicellular tissues can also push against the matrix, causing emergent compression.
"The situation has obliged them to contract and pull back the rockets," said Jeremy Issacharoff, the Israeli deputy chief of mission in Washington.
Such springs exert forces that push when contracted, or pull when extended, in proportion to the displacement of the spring from its equilibrium position.
Majno also proposed a mechanism of protein leakage, namely that histamine and other vascular permeabilizing agents induced endothelial cells to contract and pull apart to form intercellular (paracellular) gaps of sufficient size to permit plasma-protein extravasation.
