Medically reviewed by Huma Sheikh, MD Neurons are the cells in our body that are responsible for transmitting electrical ...

1 Interneurons Interneurons, also known as relay neurons, connect multiple regions of the ... and myelin sheaths surrounding the axon that accelerate action potential propagation. Neurons can also be ...

Forget the traditional tubular shape—researchers are investigating a pearl-on-a-string formation for axons, unlocking new ...

But neurons are not alone in the brain or elsewhere in the nervous system: Brain cells called glia play various supporting roles to keep the system running smoothly. Between the axon of a ...

but axons are generally longer and sometimes an axon can be up to a meter long.. In some neurons, axons are covered with a thin layer of fat called myelin, which acts as an insulator. It helps ...

(A, B) Neurons are specialized eukaryotic ... and determine the radius of the axon. (G) Actin filaments are arranged into networks. These networks can have many architectures, including the ...

Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.

but possibly attractant for some neurons, also a nerve growth factor Secreted and cell surface molecules Multimeric receptor complexes on axons or dendrites and can regulate gene expression ...

Axons connect neurons across great distances in the nervous system, and this distance is a fundamental vulnerability for neurons. Maintenance of functional connectivity requires robust mechanisms for ...
