The three basic components of all connective tissues are :

Options

A. free exposed surface, exocrine secretions, endocrine secretions
B. fluid matrix, cartilage, osteocytes
C. specialized cells, extracellular protein fibers, ground substance
D. satellite cells, cardiocytes, osteoeytes

Answer

To answer the question about the three basic components of all connective tissues, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Connective Tissue**:
- Connective tissue is one of the four main types of tissues in the body (the others being epithelial, muscle, and nervous tissues).
- It is known for its role in binding and supporting other tissues, providing strength, protection, and insulation.

2. **Identifying the Components**:
- Connective tissues are primarily composed of two main elements: cells and the extracellular matrix.
- The extracellular matrix itself can be further divided into two components: protein fibers and ground substance.

3. **Listing the Basic Components**:
- The three basic components of all connective tissues can be summarized as:
- **Specialized Cells**: These are the various types of cells found in connective tissues, such as fibroblasts, adipocytes, and immune cells.
- **Extracellular Protein Fibers**: These fibers provide strength and support to the tissue. The main types include collagen, elastin, and reticular fibers.
- **Ground Substance**: This is the non-cellular material that fills the space between the cells and fibers. It can be liquid, gel-like, or solid, depending on the type of connective tissue.

4. **Conclusion**:
- Therefore, the three basic components of all connective tissues are specialized cells, extracellular protein fibers, and ground substance.

### Final Answer:
The three basic components of all connective tissues are:
1. Specialized Cells
2. Extracellular Protein Fibers
3. Ground Substance
