Question

Which of the following sequences accurately describes the pathway of communication between neurons?

a) Axon terminal, dendrite, cell body
b) Dendrite, axon, cell body
c) Cell body, axon, dendrite
d) Dendrite, cell body, axon

Answer 1

The pathway of communication between neurons follows this sequence: dendrite, cell body, axon. Dendrites receive signals, which move to the cell body for processing, and then the axon carries the signal away from the cell body to the axon terminals and onto the next neuron.

Step-by-step explanation:

The correct sequence that accurately describes the pathway of communication between neurons is 'd) Dendrite, cell body, axon'. Here is a step-by-step breakdown of this pathway:

1. Dendrites are the structures on a neuron that receive signals from the axon terminals of other neurons.
2. After receiving a signal, the dendrites convey this electrical impulse to the cell body (also known as the soma), which contains the nucleus and is responsible for processing the information.
3. Once integrated in the cell body, the signal reaches the axon hillock at which point it can trigger an action potential if the threshold is reached.
4. The axon then transmits the electrical signal away from the cell body towards the axon terminals. The axon may be covered with a myelin sheath, which helps to speed up signal conduction.
5. Finally, the axon terminals release neurotransmitters into the synapse, thereby communicating with the dendrites of the next neuron in the chain.
