What type of cell produces connective tissue fibers?Multiple ChoiceMast cellOsteoclastMacrophageFibroblast

To determine which type of cell produces connective tissue fibers, let's analyze each option:

1. Mast cell: These cells are involved in the immune response and release histamine and other chemicals during inflammatory and allergic reactions. They do not produce connective tissue fibers.

2. Osteoclast: These are large cells that break down bone tissue. They are involved in bone resorption, not in the production of connective tissue fibers.

3. Macrophage: These are cells that engulf and digest cellular debris, foreign substances, and pathogens. They are part of the immune system and do not produce connective tissue fibers.

4. Fibroblast: These are the primary cells responsible for producing and maintaining the extracellular matrix and connective tissue fibers, such as collagen and elastin.

Based on this analysis, the correct answer is:

Fibroblast
