A hormone that is secreted by the thyroid gland that lowers osteoclast activity in proportion to osteoblast activity.


The process of maintaining a stable internal environment.


A cell found in bones that builds bone tissue by secreting collagen into bone tissue spaces; the collagen binds to calcium and forms the tough tissue within bones.


A cell found in bones that secretes hydrochloric acid that breaks down bone the bonds between calcium and collagen; the calcium is released from bone.
