What are the two types of synapses?

The action potential is generated in response to a stimulus and travels along the length of the axon, transmitting the nerve impulse. The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane..A synapse is a junction between two neurons that allows the transmission of a nerve impulse from one neuron to anotherImpulse transmission across an electrical synapse is always faster than that across a chemical synapse because electrical current can flow directly from one neuron into the other. Chemical synapses, on the other hand, rely on the release of neurotransmitters to transmit impulses.
