[The activation of blood-vessel smooth muscles increases the resistance to compression deformation].
In cylindric fragments of the rat tail arteries, activation of the smooth muscle with noradrenaline was found to enhance the vessels' rigidity both in stretching and in compression, i.e., the activation of the smooth muscle layer decreased the arteries' pliability.
