osteoclast
osteoclasts
The cell that breaks down bone is called the osteoclast.
Osteoclasts are the cells responsible for breaking down bone tissue in a process known as bone resorption. They secrete acid and enzymes that degrade the bone matrix, allowing for the remodelling and repair of bones.

When a bone breaks, the body initiates a process called bone remodeling. Osteoclasts are cells that break down and remove the damaged bone tissue, while osteoblasts come in to build new bone tissue to repair the fracture. This process helps to remodel and strengthen the bone at the site of the break.
There is not a particular "cell" that breaks down the nucleus during the cell process of mitosis. However, the nucleus does begin to break down in the phase known as prophase/prometaphase.
