Which of the following descriptions highlights how conduction of a message from one neuron to another (synaptic transmission) most often takes place? The dendrite of one neuron connects to the axons of the other and chemical stimulation is carried across the membrane. The neurons form a temporary axon-dendrite bond. An electrical spark jumps from the axon to the dendrites across the synapse. A chemical is released from the axon terminals and crosses the synaptic gap to the dendrite of another neuron.

The messages in the brain are sent and received from various parts of body and the central nervous system through electric current. These electric currents, when transmitted between the nerve cells, allow humans to sense the world, think and control different parts in their body. Nerve conduction is the general term that is used for electrical signals that are carried by neurons. To understand the process of nerve conduction, it is important to understand the structure of a neuron. The neurons have majorly have four sections, Dendrites, which are long branches that receive impulse from other neurons; Cell Body, that helps in nutrition of the neuron; Axon, which stimulates the signal generation; and Axon terminal, which passes the information to the next neuron. The process of nerve conduction is as following: When there is no stimulation from the impulse, a neuron is said to be in resting phase. The nerve cells possess a potential difference along the axon which is known as resting potential. The resting potential of a neuron is -70 mV. The membrane is negatively charged because there is lower concentration of potassium ions inside whereas it is charged positively outside because there is higher concentration of sodium ions. When a neuron receives stimulation from an impulse, an action potential is generated. Now, the membrane becomes permeable which results in negative charge outside and positive charge inside of the membrane. This potential generated at this phase is called action potential. As the action potential reaches the maximum value, the potential of the membrane reverses. By this process, the impulse reaches to the nerve ending where chemicals called neurotransmitters are released from axon terminal. These neurotransmitters cross the synapse and reach the dendrite of the next neuron.Answer: A chemical is released from the axon terminals and crosses the synaptic gap to the dendrite of another neuron. As explained above, a chemical called neurotransmitters are released from the axon terminals after the sequential process of nerve conduction. These neurotransmitters cross the synapse and reach to the dendrite of the next nerve cell where the nerve conduction takes place again.
