Select correct statements about electrical synapse.

(a) Transmission of impulse is faster than chemical synapse.

(b) These are rare in our system

(c) Synaptic cleft is filled with neurotransmitters.

Electrical synapses, also known as gap junctions, allow direct electrical communication between cells. They have a faster transmission of impulses compared to chemical synapses because they permit the direct flow of ions and electrical signals between connected cells, without the need for neurotransmitters. Electrical synapses are rare in our system. they are common in some invertebrates.

In electrical synapses, the cells are connected by gap junctions, and there is no synaptic cleft filled with neurotransmitters. Instead, the gap junctions form channels that directly link the cytoplasm of the two cells, allowing ions and small molecules to pass directly from one cell to another.
