Limestone Coal Formation

The Limestone Coal Formation (see Browne et al., 1999, fig. 4) comprises sandstone, siltstone and mudstone, mostly in repeated upward-coarsening cycles, though some fine-upwards. The cycles are usually capped by seatearth and coal. The siltstone and mudstone are usually grey to black, while the sandstone is usually fine- to medium-grained and ...

Which effect results from activation of beta2 receptors?

Vascular and nonvascular smooth muscle relaxation is results from activation of beta2 receptors.. Smooth muscle relaxes when these receptors are stimulated, which may lead to peripheral vasodilation, which then produces hypotension and reflex tachycardia.The desired therapeutic outcome is bronchodilation, which is induced by stimulation of beta-2 receptors in the lungs.
