  • There are four different ways an axon can take before reaching its terminal.
  • This process coupled with actin-associated processes result in the overall directed growth of an axon.
  • An axon cell accepts input only from this neighbor, but makes its own output available to all its neighbors.
  • Since an axon can be unmyelinated or myelinated, the action potential has two methods to travel down the axon.
  • After an axon has grown and connected with its target cell, the diameter of the axon may increase as much as fivefold.
  • Despite the appearance of attaching to an axon, cell signaling is still required for complete synaptic formation.
  • Once a neuron is in place, it extends dendrites and an axon into the area around it.
  • However, not all sensory neurons convert their external signals into action potentials; some do not even have an axon!
  • The structure of the growth cone changes whenever an axon reaches a territory not previously innervated, or if a choice in direction is required.
  • Once an axon is degenerated, it cannot regenerate like myelin, thus making research to promote remyelination that much more important.
  • The term neurite is used to describe either a dendrite or an axon, particularly in its undifferentiated stage.
  • If an axon that is not fully developed is cut, the polarity can change and other neurites can potentially become the axon.
  • The material were brought by the train to base of the hill where is situated the village of Ghelari and by there with an axon cart.
  • The most notable evidence that remyelination has taken place on an axon is its thin myelin sheath created by an oligodendrocyte.
  • Neural units The brain is made up of individual units that contain specialized features such as dendrites, a cell body, and an axon.
  • The blank neighbors, which receive a neural growth signal, turn into either an axon cell or a dendrite cell.
  • Similarly, in an axon, some of the current traveling longitudinally through the axoplasm will escape through the membrane.
  • An orthodromic impulse runs along an axon in its normal or anterograde direction, away from the soma.
  • Although it limits the frequency of firing, the absolute refractory period ensures that the action potential moves in only one direction along an axon.
  • On the left panel an axon initiates its projection within the tube.
