The combining form oste/o means “bone” and is the main element in each of the following terms. You choose the correct suffix to complete the term. Drag the terms to the blanks to correctly complete each statement. genic clast blast genesis porosis cyte The osteo____ process begins with osteo____, which produce the matrix of new bone tissue. Osteo____ has begun. Once these cells incorporate into new bone, they are termed osteo____. These cells maintain matrix. Osteo____ are produced by bone marrow. A delicate balance must be maintained between cells that remove matrix and cells that produce matrix. If more matrix is removed than produced, osteo____ will result.
The Correct Answer and Explanation is:
The correct suffixes to complete the osteo- terms are as follows:
- Osteogenesis: The osteo- process begins with osteoblasts, which produce the matrix of new bone tissue.
- Osteoblasts: These are the cells that begin the process of bone formation by producing the matrix.
- Osteocytes: Once osteoblasts incorporate into new bone, they are termed osteocytes. These cells maintain the matrix.
- Osteoclasts: Osteoclasts are produced by bone marrow. They are the cells that break down and resorb the bone matrix.
- Osteoporosis: A delicate balance must be maintained between osteoclasts (cells that remove matrix) and osteoblasts (cells that produce matrix). If more matrix is removed than produced, osteoporosis will result.
Explanation:
- Osteogenesis refers to the formation of bone, which is initiated by osteoblasts.
- Osteoblasts are responsible for bone formation. They secrete collagen and other proteins that form the bone matrix.
- Osteocytes are mature bone cells that develop from osteoblasts. They become embedded in the bone matrix they produced and help maintain the bone structure.
- Osteoclasts are large cells that break down the bone matrix, playing a critical role in bone remodeling by resorbing bone tissue.
- Osteoporosis is a condition characterized by weak and brittle bones, which occurs when osteoclast activity exceeds osteoblast activity, resulting in a loss of bone density.
In the healthy process of bone remodeling, osteoblasts and osteoclasts must work in harmony to balance bone formation and resorption. When this balance is disrupted, disorders like osteoporosis can develop.
