Interneuron

As interneurons, also switching between neurons or neurons, nerve cells are called, with all its Endknöpfchen ( extensions ) in a specifically defined area of ​​the central nervous system (CNS ) and are connected there between two or more neurons. In contrast to the projection neurons, they do not have long axons that extend to distant regions of the CNS. Enter received pulses directly to adjacent nerve cells. Interneurons are inhibitory and GABAergic usually.

In a narrower sense are interneurons neurons that are connected in mehrsynaptischen reflex arcs between sensory and motor neurons, especially in invertebrates. Several interneurons can be arranged in functional chains.

Are also called interneurons connecting nerve cells in the spinal cord run through the reflex arcs. The Renshaw inhibition is through these interneurons.

In the brain, the term interneurons for nerve cells with relatively short axons called ( type II Golgi cells). These are compared with the projection neurons with long axons.

Also in the ENS ( Enteric nervous system) sensory interneurons occur as descendants of the neural crest and form here with excitatory and inhibitory motor neurons and sensory neurons of a complicated system, the ENS.
