The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks which part is NOT found in a unipolar neuron. The options given are cell body, dendrites, axon, and none of these. 2. **Identifying Neuron Types**: There are three main types of neurons: multipolar, bipolar, and unipolar. Each type has a different structure. 3. **Characteristics of Unipolar Neurons**: - Unipolar neurons have a single process that extends from the cell body, which then divides into two branches. - They typically consist of a cell body and an axon, but they lack dendrites. 4. **Analyzing the Options**: - **Cell Body**: Present in unipolar neurons. - **Dendrites**: Absent in unipolar neurons. - **Axon**: Present in unipolar neurons. - **None of these**: This option suggests that all parts are present, which is incorrect. 5. **Conclusion**: Since unipolar neurons do not have dendrites, the correct answer is that they are composed of all the following parts except dendrites. ### Final Answer: The part that is NOT found in a unipolar neuron is **dendrites**. ---
