"Axon" Example Sentences
1. The axon is a long, slender process that conducts electrical impulses.
2. Damage to the axon can lead to impaired communication between neurons.
3. Myelin sheaths are fatty coatings that insulate axons and facilitate rapid conduction.
4. Axon terminals release neurotransmitters from the presynaptic neuron to the postsynaptic neuron.
5. Axons can vary in length from a few micrometers to over a meter in length.
6. Some neurons have unmyelinated axons, which conduct impulses more slowly.
7. Axon growth cones extend from the tip of developing axons and guide their path to target cells.
8. The myelin sheath is produced by glial cells called Schwann cells in the peripheral nervous system.
9. The axon hillock is the initial segment of the axon where action potentials are generated.
10. Axonal transport allows proteins and organelles to be transported between the cell body and the axon terminals.
11. Axons can branch and form multiple axon terminals to communicate with different target cells.
12. Axonal degeneration occurs in many neurodegenerative diseases, leading to loss of function.
13. Action potentials are propagated down the axon by the opening and closing of ion channels in the membrane.
14. Electrical synapses allow for direct communication between neurons through gap junctions in their axons.
15. Axons are part of the efferent division of the nervous system, carrying signals away from the central nervous system.
16. Membrane potential changes in the axon can be detected using electrodes placed on the axon surface.
17. The size and shape of the axon affect its resistance to electrical current and conduction velocity.
18. Axonal sprouting can occur after injury to the nervous system, as the axons attempt to regenerate.
19. The axon cytoskeleton is composed of microtubules and intermediate filaments that provide structural support.
20. Fast axonal transport is driven by motor proteins called kinesins and dyneins that move along microtubules.
21. Voltage-gated ion channels in the axon membrane are important for generating and propagating action potentials.
22. Retrograde transport allows for signaling proteins and other molecules to be transported from the axon terminals to the cell body.
23. Axon guidance molecules, such as netrins and semaphorins, play a critical role in directing axonal growth.
24. Axons can form connections with other axons, allowing for complex neural networks to be formed.
25. In demyelinating diseases, such as multiple sclerosis, the myelin sheath is damaged, leading to impaired axon function.
26. The all-or-none principle applies to action potentials in the axon, meaning that they either occur fully or not at all.
27. Saltatory conduction occurs in myelinated axons, where the action potential jumps from one node of Ranvier to the next.
28. An axon injury can lead to axonal swelling and degeneration, as well as activation of the immune system.
29. Axons can release neuropeptides, such as enkephalins and endorphins, which modulate pain perception.
30. Axon collaterals can form synapses with other neurons, allowing for amplification of signals and computation.
