Identify the incorrect statement

Options

A. tendons connect skeletal muscle with bones
B. ligaments connect bones with bones
C. adipose tissue stores fat
D. matrix of cartilage is filled with mast cells and macrophages

Answer

To identify the incorrect statement from the provided options, we will analyze each one step by step.

### Step-by-Step Solution:

1. **Option 1: Tendons connect skeletal muscle with bones.**
- This statement is correct. Tendons are indeed connective tissues that connect skeletal muscles to bones.

2. **Option 2: Ligaments connect bones with bones.**
- This statement is also correct. Ligaments are connective tissues that connect one bone to another.

3. **Option 3: Adipose tissue stores fat.**
- This statement is correct as well. Adipose tissue is composed of adipocytes, which store lipids (fats) in the form of triglycerides.

4. **Option 4: The matrix of cartilage is filled with mast cells and macrophages.**
- This statement is incorrect. The matrix of cartilage is primarily composed of chondrocytes and extracellular matrix, not mast cells or macrophages. Mast cells and macrophages are typically found in areolar connective tissue, not in cartilage.

### Conclusion:
The incorrect statement is **Option 4: The matrix of cartilage is filled with mast cells and macrophages.**
