List the cellular structures over which an action potential travels starting at the dendrites and traveling to where neurotransmitter molecule are released

Answer;

-Dendrites

-Axon

-Synaptic vesicle

-Synapse

Explanation;

-The nervous system is made up of neurons, the specialized cells that can receive and transmit chemical or electrical signals, and glia, the cells that provide support functions for the neurons.

-Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.

-Neurons contain unique structures, dendrites and axons, for receiving and sending the electrical signals that make neuronal communication possible. Action potential travels starting from the dendrites, axon, synaptic vessicle, and then to the synapse where neurotransmitter molecules are released.

The correct answer will be

spine of dendrite→dendrite→soma, cell body→axon→axon terminal→Ion channels→ligand receptor

Explanation:

A neuron acts as an electrical device as it transmits the signals in the form of action potential from one neuron to another neuron.

Two neurons communicate with each other at the synaptic junction where signals from the presynaptic axon terminal are transferred to the postsynaptic dendrite.

The synapse, the spine protrusions of the dendrite receive a signal from the axon in the form neurotransmitters. This cause generation of the action potential which is transferred to the soma cell body of the neuron.

From soma, the impulse travels through a long tubule structure called axon with nodes of Ranvier and reach the axon terminal.

At axon terminal, the potential leads to the opening of the ion channels which leads to the release of the neurotransmitter. The neurotransmitter then binds to the ligand-receptor of the next dendrite and the process continues.

Thus, the cellular structure arranged in sequence will be the spine of dendrite→→soma, cell body→axon→ axon terminal→Ion channels→ligand receptor
