Explain the differences between osteoporosis osteoclasts and osteocytes. How do these cells work together to remodel bone? What happens if the activities of osteoblasts and osteoclasts are imbalanced

Osteoporosis is a condition when bones get porous and break easily, while

Osteocytes are what people call virgin bone cells (or osteoblasts) once they become hardened into place.

Osteoclasts break down bone when it grows beyond where it needs to be.

Explanation:

Throughout our lives, bone is deposited, broken down, and replaced. When an arm or leg is broken, the blood vessels at the area have the ability to increase calcium phosphate deposition to help heal the break. Newly trapped osteoblasts, called osteocytes, form the new bone framework. These cells can no longer produce new bone and become the basic framework for the new bone.

Osteoclasts, the second type of bone cell, are specialized to dissolve bone. As bones grow, they need to be reshaped. Simply add- ing layer upon layer of calcium phosphate would not maintain the proper shape of the bone. Therefore, as bones grow, the osteoclasts secrete enzymes that help dissolve certain areas of the bone.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
