WebFeb 28, 2024 · The synapse or “gap” is the place where information is transmitted from one neuron to another. Synapses usually form between axon terminals and dendritic spines, but this is not universally true. There are also axon-to-axon, dendrite-to-dendrite, and axon-to-cell body synapses.

There are two fundamentally different types of synapses: • In a chemical synapse, electrical activity in the presynaptic neuron is converted (via the activation of voltage-gated calcium channels) into the release of a chemical called a neurotransmitter that binds to receptors located in the plasma membrane of the postsynaptic cell. The neurotransmitter may initiate an electrical response or a secondary messenger pathway that may either excite or … WebCompare a contrast chemical vs electrical synapses: Electrical Chemical Faster speed of transmission Slower speed of transmission Bidirectional transmission Unidirectional transmission Impulse is transmitted through gap junctions or low resistance bridges Uses neurotransmitters (chemical mediators) for the transmission of an impulse They are ... numbers psychostick
