What are the functions of desmosomes and gap junctions in cardiac muscle cells?

Explanation

### Step-by-Step Solution:

1. **Understanding Desmosomes**:
- Desmosomes are specialized structures that function to anchor adjacent cardiac muscle cells together. They are crucial for maintaining the structural integrity of the heart during contraction.

2. **Function of Desmosomes**:
- The primary function of desmosomes in cardiac muscle cells is to prevent the separation of cells during the mechanical stress of contraction. They achieve this by binding filaments that join the cells together, ensuring that the heart can contract effectively without tearing apart.
