Question:
The most common cell of connective tissue is
The most common cell of connective tissue is
Show Hint
The terms Fibroblast (active form) and Fibrocyte (inactive/resting form) represent different functional states of the same cell type, which is the most abundant cell in general connective tissues.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Connective tissue proper consists of cells, fibers, and ground substance.
The cellular population is divided into fixed (resident) cells and transient (wandering) cells.
Step 2: Detailed Explanation:
Let us evaluate the abundance of the resident cell types in connective tissue proper:
- Fibroblasts and Fibrocytes:
These are the most numerous and widely distributed cells in connective tissue proper.
They are responsible for synthesizing the extracellular matrix, including collagen, elastic, and reticular fibers, as well as the glycosaminoglycans of the ground substance.
The term "fibroblast" refers to the metabolically active, spindle-shaped cell with abundant rough endoplasmic reticulum.
The term "fibrocyte" refers to the mature, quiescent (inactive) state of the cell, which is smaller, spindle-shaped, and has condensed chromatin.
Because most connective tissue in a mature animal is in a resting, maintenance state, fibrocytes represent the most common cellular component.
- Reticular cells:
These are specialized fibroblasts that produce reticular fibers (collagen type III) and are restricted primarily to lymphoid organs and bone marrow.
- Macrophages:
These are phagocytic cells derived from monocytes, less numerous than fibroblasts under normal non-inflammatory conditions.
- Mesenchymal cells:
These are multipotent embryonic stem cells that are abundant in developing embryonic tissue but rare in mature adult connective tissues.
Step 3: Final Answer:
The most common cell of connective tissue is the Fibrocyte (or Fibroblast).
