What roles do the dendrites, cell body, and axon play in communication of signals?

Explanation

### Step-by-Step Solution:

1. **Understanding the Structure of a Neuron**:
- Neurons are specialized cells that transmit signals in the nervous system. They consist of three main parts: dendrites, cell body (soma), and axon.

2. **Role of Dendrites**:
- Dendrites are branch-like structures that extend from the cell body. Their primary role is to receive incoming signals from other neurons or sensory receptors. They act as the input zone of the neuron.
