What is synapse and name the elements that are present in it?

Explanation

**Step-by-Step Solution:**

1. **Definition of Synapse**: A synapse is defined as the junction or connection point between two nerve cells (neurons). It is the site where the transmission of nerve impulses occurs from one neuron to another.

2. **Function of Synapse**: The primary function of a synapse is to facilitate the transmission of impulses. When a nerve impulse reaches the end of a neuron, it triggers the release of neurotransmitters that cross the synapse to transmit the signal to the next neuron.

3. **Elements of a Synapse**: A synapse is composed of three main elements:
- **Pre-synaptic Membrane**: This is the membrane of the neuron that sends the signal. It contains vesicles filled with neurotransmitters.
