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

The question asks for the three basic components of all connective tissues. To answer this, we can break it down into steps:

### Step-by-Step Solution:

1. **Understanding Connective Tissue**: Connective tissues are one of the four main types of tissues in the body (the others being epithelial, muscle, and nervous tissues). They play a crucial role in supporting, binding, and protecting other tissues and organs.

2. **Identifying the Components**: The three basic components of connective tissues are:
- **Cells**: These are the living components of connective tissue. Different types of cells are present depending on the specific type of connective tissue (e.g., fibroblasts, adipocytes, macrophages).
- **Fibers**: These provide strength and support to the tissue. There are three main types of fibers found in connective tissues:
- Collagen fibers (provide tensile strength)
- Elastic fibers (allow for stretch and recoil)
- Reticular fibers (form a supportive mesh)
- **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. The ground substance contains various molecules, including glycoproteins and proteoglycans.

3. **Conclusion**: The three basic components of all connective tissues are:
- Cells
- Fibers
- Ground Substance

### Final Answer:
The three basic components of all connective tissues are cells, fibers, and ground substance.
