The largest number of cell bodies of neurons in our body is found in :

Options

A. brain
B. tongue
C. kidneys
D. stomach

Explanation

### Step-by-Step Solution:

1. **Understanding Neurons**: Neurons are the fundamental units of the nervous system, responsible for transmitting information throughout the body. Each neuron consists of a cell body (soma), dendrites, and an axon.

2. **Identifying the Options**: The question provides four options: brain, tongue, kidneys, and stomach. We need to determine which of these contains the largest number of neuron cell bodies.

3. **Analyzing Each Option**:
- **Brain**: The brain is the central organ of the nervous system and contains a vast number of neurons, including their cell bodies. It is known to have billions of neurons, making it the most significant site for neuron cell bodies.
- **Tongue**: The tongue primarily consists of muscle tissue and epithelial cells. While it does have some sensory neurons (like taste receptors), it does not contain a large number of neuron cell bodies compared to the brain.
- **Kidneys**: The kidneys are primarily involved in filtering blood and do not contain neuron cell bodies. They are made up of nephrons, which are functional units for filtration, not neurons.
- **Stomach**: The stomach is involved in digestion and contains various types of cells, including parietal cells, but it does not have a significant number of neuron cell bodies.

4. **Conclusion**: After analyzing all the options, it is clear that the largest number of cell bodies of neurons in our body is found in the **brain**.

### Final Answer:
The largest number of cell bodies of neurons in our body is found in the **brain**.
