Synapse is

Options

A. junction between two axons
B. junction between two dendrites
C. junction between axon and dendrite
D. junction between cell bodies.

Explanation

**Step-by-Step Solution:**

1. **Understanding Neurons**: Begin by recognizing that neurons are the fundamental units of the nervous system. They consist of several parts: dendrites, cell body, axon, and axon terminals.

2. **Identifying the Structure**: In a typical neuron, dendrites receive signals, the cell body processes them, and the axon transmits the signals away from the cell body. The axon terminals are where the neuron communicates with other neurons.

3. **Defining Synapse**: A synapse is a specialized junction that occurs between two neurons. It is the site where the axon terminal of one neuron comes into close proximity with the dendrite of another neuron.

4. **Analyzing Options**:
- Option A: Junction between two axons - Incorrect, as synapses do not occur between axons.
- Option B: Junction between two dendrites - Incorrect, as synapses do not occur between dendrites.
- Option C: Junction between axon and dendrite - Correct, as this describes the synapse accurately.
- Option D: Junction between cell bodies - Incorrect, as synapses do not occur between cell bodies.

5. **Conclusion**: Based on the definitions and analysis of the options, the correct answer is **Option C: Junction between axon and dendrite**.
