82 LO82 Identify the mechanism by which neurons can transport information within the cellWhich of the following best describes an example of electrical communication neuron?Actions potentials traveling from the axon hillock through the axon reaching the axon terminal of a neuron.Opening of K+ channels causing depolarization and leading to action potentials within a neuron.A neuron responding to the release of neurotransmitters from a pre-synaptic neuron.Neurotransmitters released from pre-synaptic neurons to the post-synaptic neuron.

Neuron:- is a nerve cell, and it is an electrically excitable cell. It communicates with other cells (neurons, muscle cells, or glandular cells) via a gap junction called a synapse. An electrical charge called action potential moves along the membrane potential. It is necessary for the passage of impulses from one neuron to another. Synapses are usually located between axon terminals and dendritic nerve endings. But there are other communications as well. For example, axon-to-axon, dendrite-to-dendrite, and axon-to-cell body synapses. The neuron that passes the neuro signal is called the presynaptic neuron, and the one that receives the neuro signal is called the postsynaptic neuron. Types of synapses: chemical and electrical. Electrical synapse- In this type of synapse, the postsynaptic and presynaptic membranes lie very close. They are connected via channel proteins forming gap junctions. These gap junctions allow an electric current to pass directly from one neuron to another. The ions that carry the current, along with ions and other molecules, such as ATP, can diffuse through the large gap junction pores. Based on the above explanation, we can concludes:- Action potential traveling from the axon hillock through the axon, reaching the axon terminal. Incorrect opening of K+ channels leading to depolarisation and leading action potential within neurons. Correct; The ions are messengers in electrical transmission A neuron responding to the release of neurotransmitter from the pre-synaptic neuron. Incorrect- involvement of neurotransmitter is the chemical transmission. The neurotransmitter is released from presynaptic neuron to postsynaptic neuron- Incorrect- This is a chemical transmission
