Structurally, neurons are unique because they are the only cells in the body that have :

Options

A. lacunae and canaliculi
B. axons and dendrites
C. satellite cells and neuroglia
D. soma and stroma

Answer

### Step-by-Step Solution:

1. **Understanding Neurons**: Neurons are specialized cells in the nervous system responsible for transmitting information throughout the body. They have a unique structure that distinguishes them from other cell types.

2. **Identifying Unique Structures**: The question asks what makes neurons structurally unique. We need to identify specific structures that are characteristic of neurons.

3. **Examining the Options**:
- **Reukinone**: This term refers to a space in bone tissue (the lacunae) where osteocytes reside. It is not related to neurons.
- **Axons and Dendrites**: These are specialized structures of neurons. Axons transmit signals away from the cell body, while dendrites receive signals from other neurons. This is a key feature that makes neurons unique.
- **Satellite Cells**: These are glial cells that support neurons but are not unique to neurons themselves.
- **Soma and Stoma**: The soma refers to the cell body of the neuron, but "stoma" refers to the supportive framework in tissues and is not specific to neurons.

4. **Conclusion**: Based on the examination of the options, the correct answer is that neurons are unique because they have axons and dendrites.

### Final Answer:
Neurons are unique because they are the only cells in the body that have axons and dendrites.
