Select the incorrectly matched pair from following :

Options

A. Neutrons- Nerve cells
B. Fibroblast- Areolar tissue
C. Osteocytes- Bone cells
D. Chondrogytes - Smooth muscle cells

Answer

To solve the question regarding the incorrectly matched pair, we will analyze each option provided:

1. **Neurons - Nerve Cells**:
- Neurons are indeed known as nerve cells. Their primary function is to transmit signals throughout the body, including sending information to and from the brain. This pairing is correctly matched.

2. **Fibroblast - Areolar Tissue**:
- Fibroblasts are a type of cell found in connective tissue, specifically in areolar tissue. They are responsible for producing and maintaining the extracellular matrix and collagen, which helps keep the tissue spongy. This pairing is also correctly matched.

3. **Osteocytes - Bone Cells**:
- Osteocytes are specialized bone cells that maintain bone tissue. They play a crucial role in the formation and maintenance of bone. This pairing is correctly matched as well.

4. **Chondrocytes - Smooth Muscle Cells**:
- Chondrocytes are the cells found in cartilage and are responsible for producing the cartilage matrix, which includes collagen and proteoglycans. They are not smooth muscle cells. Smooth muscle cells are a different type of cell found in the walls of hollow organs. Therefore, this pairing is incorrectly matched.

Based on the analysis, the incorrectly matched pair is **Chondrocytes - Smooth Muscle Cells**.

### Steps:
1. Identify each pair and their definitions.
2. Verify the accuracy of each pairing based on biological knowledge.
3. Conclude which pair is incorrectly matched.
