Your teacher asks you to describe the sequence of parts of a neuron that the impulse travels to during neural conduction. There is a small gap between two synapsed neurons, where neurotransmitters are released from one neuron to pass the signal to the next neuron. Axons : there is only one per neuron and they are a long and thin process and that carry impulses away from cell body. A hermit who lived in a tree. This figure depicts what a dendrite looks like in a neuron: The functions of dendrites are to receive signals from other neurons, to process these signals, and to transfer the information to the soma of the neuron. The cell is now hyperpolarized. Careers. Some types of neurons have dendritic spines on the dendrites, which are small protrusions that project from the dendrites and which have neurotransmitter receptors that increase the detection of neurotransmitters. Examples of neurotransmitters are dopamine, serotonin, norepinephrine, GABA and glutamate. 13. . There are numerous spines on dendrites that provide the surface for other nerve cells to synapse on or to form a neuronal junction (the platform of transmission of an electric nerve between two neurons).
