Answer: adenylyl cyclase inositol triphosphate mainly known as IP3 causes the release of Calcium ions directly from the inracellular stores and causea contraction.
Explanation:
IP3, inositol phosphate is a second messenger a signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by an enzyme phospholipase C.
IP3 binds to the calcium channels and opens Ca2+ channels that are embedded in the ER membrane, releasing Ca2+ into the cytosol. Calcium ions released may cause contraction and regulate the Ca2+ channels in the membranes.

Explanation:
Bone healing has three main processes and these stages are overlapping to each other. These processes are inflammation,bone production and bone remodeling.
Inflammation occurs immediately after the fracture and last several days. It enables clotting of blood. It provides initial structure stability and framework for new bone formation.
Bone production occurs when the clotted blood formed by inflammation is replaced with fibrous tissues and cartilage as soft callous.
Bone remodeling is the final stage of the bone healing and it goes on for several months. Bone continues to form and compact. Bones returns to its original shape and the blood circulation in that area improves.
