Multipolar neurons have

Options

A. One axon and several dendrites
B. One dendron and several axons
C. They are most common and present in brain and spinal cord
D. Both (1) & (3) are correct

Answer

### Step-by-Step Solution:

1. **Understanding Neuron Classification**: Neurons can be classified based on their shape into four main types: unipolar, bipolar, multipolar, and pseudo unipolar.

2. **Identifying Multipolar Neurons**: Among these types, multipolar neurons are the most common. They are characterized by having multiple extensions from the cell body.

3. **Structure of Multipolar Neurons**: A multipolar neuron consists of:
- **One Axon**: This is the long projection that transmits signals away from the cell body.
- **Multiple Dendrites**: These are the shorter branches that receive signals from other neurons.

4. **Location of Multipolar Neurons**: Multipolar neurons are primarily found in the central nervous system (CNS), which includes the brain and spinal cord.

5. **Example of Multipolar Neurons**: A well-known example of a multipolar neuron is the Purkinje cell, which is located in the cerebellum of the brain.

6. **Conclusion**: Therefore, the key characteristics of multipolar neurons are that they have one axon, several dendrites, are the most common type of neuron, and are predominantly found in the brain and spinal cord.

### Final Answer:
Multipolar neurons have one axon and several dendrites, and they are the most common type of neuron found in the brain and spinal cord.
