  • Neurotoxic damage to axon terminals has been shown to persist for more than two years.
  • It has concentric layers like an onion, which form around the axon terminal.
  • Once the action potential reaches the axon terminal, it will cause an influx of calcium ions into the cell.
  • Axons extend short axon terminal arbors toward neurons within a target area.
  • Lateral column axon terminals were found to contain noradrenaline storage granules and could be divided into four types.
  • The pruning that is associated with learning is known as small-scale axon terminal arbor pruning.
  • The toxin must get inside the axon terminals to cause paralysis.
  • They are found at axon terminals, as well as in somatodendritic areas of neurons within the central and peripheral nervous system.
  • In addition, long-term exposure to MDMA in humans has been shown to produce marked neurotoxicity in serotonergic axon terminals.
  • Full recovery takes 4 to 6 weeks because the body must regenerate destroyed nerve axon terminals.
  • Action potentials reach the axon terminal, where the action potential triggers the release of neurotransmitters from the neuron.
  • At the furthest end, the axon loses its insulation and begins to branch into several axon terminals.
  • Synapses can be classified by the type of cellular structure serving as the postsynaptic target, onto which the axon terminal projects.
  • Calcium channels are important for certain cell-signaling cascades as well as neurotransmitter release at axon terminals.
  • The heavy chain of the toxin is important for targeting the toxin to specific types of axon terminals.
  • One major model of the formation of the stripes seen in ocular dominance columns is that they form by Hebbian competition between axon terminals.
  • Although the mechanisms regulating pre-synaptic differentiation are unknown, the changes exhibited at the developing axon terminal are well characterized.
  • Motor proteins transport membrane protein-containing vesicles along cytoskeletal tracks to distant parts of cells such as the axon terminals of neurons.
  • When a muscle contracts, an action potential is propagated down a nerve until it reaches the axon terminal of the motor neuron.
  • The impulse flow is turned on and as a result 5-HT is released at the axon terminal.
