The length of the axon between each gap, which is wrapped in myelin, is referred to as an axon segment. At the end of the axon is the axon terminal, where there are usually several branches extending toward the target cell, each of ...
WebThese molecules are unconventional in that they are not stored in synaptic vesicles and may carry messages from the postsynaptic neuron to the presynaptic neuron. Also, rather than interacting with receptors on the plasma membrane of their target cells, the gasotransmitters can cross the cell membrane and act directly on molecules inside the cell.
