In neuron, conversion

Options

A. cell body
B. axonal end
C. dendritic end
D. axon

Explanation

**Step-by-Step Solution:**

1. **Understanding Neuron Structure**: A neuron consists of three main parts: dendrites, cell body, and axon. The dendrites receive signals, the cell body processes them, and the axon transmits the signals.

2. **Signal Reception**: The process starts when an electrical signal (impulse) is received by the dendrites of the neuron. This electrical signal is generated due to a stimulus.

3. **Signal Transmission**: After the dendrites receive the electrical signal, it travels to the cell body. The cell body integrates the signals and prepares to transmit them down the axon.

4. **Axon Function**: The electrical signal travels along the length of the axon until it reaches the axon terminal. This part of the neuron is crucial for the next step in signal transmission.

5. **Conversion to Chemical Signal**: At the axon terminal, the electrical signal is converted into a chemical signal. This conversion occurs when neurotransmitters are released from the axon terminal into the synaptic cleft (the gap between neurons).

6. **Neurotransmitter Function**: The released neurotransmitters then bind to the receptors on the dendrites of the next neuron, allowing the signal to continue its journey. This is how the electrical signal is transmitted chemically to the next neuron.

7. **Conclusion**: Therefore, the conversion of electrical signals to chemical signals occurs at the axon terminal, where neurotransmitters are released.

**Final Answer**: The conversion of electrical signals to chemical signals occurs at the axon terminal of a neuron.
