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 terms are:
- genic
The osteogenic process begins with osteoblasts, which produce the matrix of new bone tissue. “Osteogenic” means the formation or creation of bone. - blast
Osteoblasts are the cells that produce the matrix of new bone tissue. The term “blast” refers to immature cells that are actively involved in the creation or production of a substance, in this case, the bone matrix. - genesis
Osteogenesis has begun. “Osteogenesis” refers to the process of bone formation. The suffix “-genesis” means the process of formation or creation. - cyte
Once osteoblasts incorporate into new bone, they are termed osteocytes. “Osteocytes” are mature bone cells that maintain the bone matrix. The suffix “-cyte” refers to a mature, differentiated cell. - clast
Osteoclasts are produced by bone marrow. Osteoclasts are cells responsible for breaking down and resorbing bone tissue. The suffix “-clast” refers to cells that break down or destroy substances. - porosis
If more matrix is removed than produced, osteoporosis will result. “Osteoporosis” is a condition where bone density decreases, making bones more fragile and prone to fractures. The suffix “-porosis” refers to a condition characterized by porous or weak bones.
Explanation:
Bone formation and resorption involve a delicate balance between different types of cells:
- Osteoblasts are responsible for building the bone matrix.
- Osteocytes are mature bone cells that maintain the matrix.
- Osteoclasts break down bone tissue for remodeling and repair.
- If the activity of osteoclasts exceeds that of osteoblasts, it can lead to osteoporosis, where bones become weak and brittle.
The suffixes indicate the role or status of the cells involved in the process of bone remodeling.
