Option: 4

Synchronization of action potentials

Answers (1)


The main characteristic of synapses between neurons is chemical transmission. Synapses are specialized junctions that allow communication between neurons. When an action potential (electrical signal) reaches the presynaptic neuron, it triggers the release of chemical neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential and, if the signal is strong enough, the generation of an action potential in the postsynaptic neuron. This chemical transmission is essential for transmitting information between neurons in the nervous system. Therefore, option 3 is the correct answer.
