Identify the character which is not related to mesenchymal connective tissue 

Options

A. Irregular shaped mesenchymal cells
B. Semifluid matrix
C. Presence of reticular fibres
D. It is refered to as Wharton's jelly in umbilical cord

Answer

### Step-by-Step Solution:

1. **Understanding Mesenchymal Connective Tissue**:
- Mesenchymal connective tissue is a type of loose, undifferentiated connective tissue found in embryos. It consists of mesenchymal cells that can differentiate into various types of cells, including those that form blood, bone, and muscle.

2. **Identifying Characteristics of Mesenchymal Connective Tissue**:
- Mesenchymal cells are irregularly shaped.
- They have a semi-fluid matrix, which is a gel-like substance that serves as the ground substance in the extracellular matrix.
- They contain reticular fibers, which form a supportive meshwork in soft tissues.

3. **Analyzing the Options**:
- **Irregular shaped mesenchymal cells**: This is a characteristic of mesenchymal connective tissue.
- **Semi-fluid matrix**: This is also a characteristic of mesenchymal connective tissue.
- **Presence of reticular fibers**: This is another characteristic of mesenchymal connective tissue.
- **Referred to as cotton jelly in umbilical cord**: This statement is incorrect because "cotton jelly" refers to Wharton's jelly, which is a type of mucoid connective tissue found in the umbilical cord, not mesenchymal connective tissue.

4. **Conclusion**:
- The character that is not related to mesenchymal connective tissue is the last option: "referred to as cotton jelly in umbilical cord."

### Final Answer:
The character which is not related to mesenchymal connective tissue is: **"referred to as cotton jelly in umbilical cord."**
