What fluid is produced by synapse?

Synapses do not produce a fluid per se; rather, they rely on neurotransmitters, which are chemical messengers that facilitate communication between neurons. When an action potential reaches the synaptic terminal, neurotransmitters are released into the synaptic cleft, the small gap between neurons. This release allows the transmission of signals from one neuron to another, enabling neural communication. Additionally, the synaptic cleft contains extracellular fluid that helps maintain the environment for neurotransmitter diffusion.
