Myelin, isolerar axon och möjliggör saltatorisk fortledning av aktionspotentialer. Bipolär neuron, har två utskott: en dendrit och ett axon.

Nervous system - Nervous system - Axon: The axon arises from the soma at a region called the axon hillock, or initial segment. This is the region where the plasma membrane generates nerve impulses; the axon conducts these impulses away from the soma or dendrites toward other neurons. Large axons acquire an insulating myelin sheath and are known as myelinated, or medullated, fibres. Myelin is

By smFISH analysis we find that prde-1 transcripts are present in neurons, as well as germ cells. Neural stem cells directly or indirectly generate all neurons and macroglial cells and guide migrating neurons by using a palisade-like scaffold made of their radial fibers. Here, we describe an unexpected role for the radial fiber scaffold in directing corticospinal and other axons at the junction … Axon definition, the appendage of the neuron that transmits impulses away from the cell body.

Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.. Depending on the type of neuron, axons greatly vary in length - many are just a millimetre or so, but the longest ones, such as

Er ændringen i membranpotentialet tilstrækkelig stor, genereres en (alt-eller-intet) elektrokemisk puls kaldet et aktionspotentiale, som bevæger sig hurtigt langs cellens axon og aktiverer synaptiske forbindelser til andre celler. "Metamorphosis" is Axon-Neuron's third studio album.

Primär-afferenta/sensoriska neuron är delvis belägna i PNS (dendrit-träd, cellkropp och delar av axonet) och delvis i CNS (axon, axongrenar, boutonger, synapser)
