Definition
An electrical synapse is a type of synapse in which electrical current freely flows from one cell into another through structures called gap junctions.
This is a type of synapse where information (in the form of neurotransmitters) is transferred from one neuron to another across a small gap.
Gap Junction: These are specialized intercellular connections that directly connect the cytoplasm of two cells, allowing various molecules and ions to pass freely between cells.
Neuroglia: Also known as glial cells, these are non-neuronal cells in the nervous system that support neurons. They provide nutrition, insulation, and help with signal transmission in the nervous system.
