Electrical vs Chemical Synapse Explained (Gap Junctions) | Clip

Welcome to Science With Tal!

In this clip of the The Neuromuscular Junction as the model of the chemical synapse video, we will cover the difference between electrical and chemical synapses. To understand them, I will present a holistic view of both and then compare them to one another based on synaptic delay, synaptic mechanism, cytoplasmic continuity, etc.

To improve the quality of my content, I highly value the feedback from the viewer so do not hesitate to give any feedback in the comment section.
