one axon

  • The soma may give rise to numerous dendrites, but never to more than one axon.
  • Multipolar neurons, such as the one shown in the image, are composed of one axon and many dendritic trees.
  • While each neuron only has one axon, it can branch into several telodendria and form presynaptic vesicles for neurotransmission at each branch.
  • Bipolar neurons have one axon and one dendritic tree at opposing ends of the cell body.
  • By definition, a pseudounipolar neuron has one axon with two branches: central and peripheral.
  • However, unlike oligodendrocytes, each myelinating Schwann cell provides insulation to only one axon (see image).
  • The cell body of a neuron frequently gives rise to multiple dendrites, but never to more than one axon, although the axon may branch hundreds of times before it terminates.
  • No neuron ever has more than one axon; however in invertebrates such as insects or leeches the axon sometimes consists of several regions that function more or less independently of each other.
  • Myelination of the axons are highly important for signalling as this improves the speed of conduction of action potentials from one axon to the next.
  • Each ommatidium is innervated by one axon bundle (usually consisting of 6-9 axons, depending on the number of rhabdomeres) and provides the brain with one picture element.
