In bipolar neuron, 1 axon and 1 dendrite directly arise from 

Options

A. cyton
B. ganglion
C. 1 & 2
D. none

Answer

To solve the question regarding the origin of 1 axon and 1 dendrite in a bipolar neuron, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Neuron Structure**:
- Neurons are specialized cells that transmit nerve impulses. They consist of three main parts: the cell body (cytone), dendrites, and axon.

2. **Identifying Bipolar Neurons**:
- Bipolar neurons are a specific type of neuron that has two distinct processes: one axon and one dendrite. This distinguishes them from other types of neurons, such as unipolar or multipolar neurons.

3. **Location of Axon and Dendrite**:
- In bipolar neurons, both the axon and the dendrite directly arise from the cytone (cell body). The cytone contains the nucleus and is the metabolic center of the neuron.

4. **Exclusion of Other Options**:
- The term "ganglion" refers to a collection of neuron cell bodies in the peripheral nervous system. While ganglion cells may receive signals from bipolar neurons, they do not give rise to the axon or dendrite of bipolar neurons.

5. **Conclusion**:
- Therefore, the correct answer to the question is that in a bipolar neuron, 1 axon and 1 dendrite directly arise from the **cytone**.

### Final Answer:
**Cytone**
