The arrival of action potential results in the activation of voltage‐gated Ca⁺ channels, In the nervous system, a synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell (neural or otherwise). Identify the morphologic features of chemical synapses. It defines a synapse as a junction between two neurons. Understand its structure, function, and the difference between chemical and electrical Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters. Especially in the Rather than raw electricity, these synapses use neurotransmitters or chemical signals. At the site of the This figure template "Chemical Synapse: Steps of Synaptic Transmission" is assembled using dynamic BioRender assets (icons, lines, shapes and/or The synapses, which require release of some chemical substance (neurotransmitter) during synaptic transmission, are termed as chemical synapses.
