Question

place the following structures in the order that an electrical impulse would travel beginning with the post - synaptic membrane. rank the options below. internode. node of ranvier. dendrites. axon terminals. axon hillock. terminal arborization. soma

Explanation:

In a neuron, after the post - synaptic membrane, the electrical impulse first reaches dendrites which receive signals. Then it moves to the soma (cell body). From the soma, it travels to the axon hillock which integrates signals and decides whether to generate an action potential. The impulse then moves along the axon, passing through internodes (the myelinated sections of the axon) and nodes of Ranvier (the gaps in the myelin sheath). Finally, it reaches the axon terminals and terminal arborization where neurotransmitters are released.

Answer:

1. Dendrites
2. Soma
3. Axon hillock
4. Internode
5. Node of Ranvier
6. Axon terminals
7. Terminal arborization
