Give scientific reasons:
Synapse acts as a one-way valve

Explanation

### Step-by-Step Solution:

1. **Definition of Synapse**: A synapse is the junction between two neurons where communication occurs. It consists of a synaptic knob (the end of the neuron) and the dendrites of the adjacent neuron.

2. **Role of Neurotransmitters**: At the synapse, neurotransmitters are released from the synaptic knobs of the presynaptic neuron. These are chemical signals that facilitate the transmission of information.

3. **Transmission of Information**: When neurotransmitters are released, they bind to specific receptors on the dendrites of the postsynaptic neuron. This binding generates an electrical signal (action potential) in the postsynaptic neuron.
