A bipolar neuron has

Options

A. Two axons and two dendrons
B. One axon and one dendron
C. Two axon and one dendron
D. One axon and two dendrons.

Answer

**Step-by-Step Solution:**

1. **Understanding Neurons**: A neuron, or nerve cell, is the fundamental unit of the nervous system. It consists of three main parts: the cell body (cyton), the axon, and dendrons.

2. **Identifying Neuron Types**: Neurons can be classified based on their structure. Bipolar neurons are one such type, characterized by having two distinct processes extending from the cell body.

3. **Structure of Bipolar Neurons**: In bipolar neurons, there is one axon and one dendron. The axon is the long branch that transmits signals away from the cell body, while the dendron (or dendrite) receives signals and brings them toward the cell body.

4. **Function of Bipolar Neurons**: These neurons are specialized sensory neurons involved in transmitting sensory information. They play a crucial role in sensory pathways related to smell, sight, touch, balance, and hearing.

5. **Choosing the Correct Option**: Given the options:
- Two axons and two dendrons
- One axon and one dendron
- Two axons and one dendron
- One axon and two dendrons

The correct answer is "one axon and one dendron," as this accurately describes the structure of a bipolar neuron.

6. **Final Answer**: Therefore, the answer to the question "A bipolar neuron has" is: **one axon and one dendron**.
