Chemicals which are released at the synaptic junction are called :

Options

A. hormones
B. neurotransmitters
C. cerebrospinal fluid
D. lymph

Explanation

### Step-by-Step Solution:

1. **Understanding the Synaptic Junction**: The synaptic junction is the point where two neurons communicate with each other. It is crucial for transmitting signals throughout the nervous system.

2. **Identifying the Chemicals Involved**: At the synaptic junction, certain chemicals are released from the axon terminal of one neuron. These chemicals play a vital role in transmitting signals to the next neuron.

3. **Function of These Chemicals**: The chemicals released at the synaptic junction act as signals that facilitate communication between neurons. They help in transferring information from one neuron to another.

4. **Naming the Chemicals**: The specific chemicals that are released at the synaptic junction are known as neurotransmitters. They bind to receptors on the dendrites of the receiving neuron, allowing the signal to continue.

5. **Evaluating the Options**: The question may provide multiple-choice answers. The correct answer to the question regarding the chemicals released at the synaptic junction is "neurotransmitters."

6. **Conclusion**: Therefore, the answer to the question is that the chemicals which are released at the synaptic junction are called neurotransmitters.
