Which is the correct direction of flow of electrical impulses?

Options

A.
B.
C.
D.

Explanation

To determine the correct direction of flow of electrical impulses in nerve cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Nerve Cells**:
- Nerve cells, also known as neurons, are the basic units of the nervous system. They consist of three main parts: the cell body, dendrites, and axon.

2. **Identifying the Components**:
- The **dendrites** are the branch-like structures that receive signals from other neurons or sensory receptors.
- The **axon** is a long, thread-like structure that transmits electrical impulses away from the cell body to other neurons or muscles.

3. **Direction of Impulse Flow**:
- The flow of electrical impulses starts at the **dendrites**, where the neuron receives signals.
- The impulse then travels through the **cell body** and down the **axon**.
- Finally, the impulse reaches the **nerve endings** at the end of the axon, where it can transmit the signal to the next neuron across a gap called the **synapse**.

4. **Conclusion**:
- Therefore, the correct direction of flow of electrical impulses is from the **dendrites** to the **axon** and then to the **nerve endings**.

### Final Answer:
The correct direction of flow of electrical impulses is from **dendrites → cell body → axon → nerve endings**.
