Oligodendrocytes
http://physrev.physiology.org/content/81/2/871
The Oligodendrocytes are located in the Central Nervous System. They are smaller than some of the other glial cells located in the Central Nervous System. They have a dense nucleus which contains dense chromatin, and dense cytoplasm and the presence of a large number of microtubules in processes to help with stability. Another unique trait of oligodendrocytes is that they lack fibrils and glycogen in the cytoplasm.
Oligodendrocytes specialize in helping to form the myelin sheath around axons in the Central Nervous System. The myelin helps regulate the axonal caliber, maintains the axons, and helps inhibit the growth and regeneration of axons. Oligodendrocytes are classified as nervous tissue because of the role that they play in the Central Nervous System.
So now I know what type of cells are responsible for making up myelin sheets that allow for signals to jump through the open spaces. Thanks! :)
ReplyDeleteI am digging the picture
ReplyDeleteAlong with your explanation, the diagram you used really helped me visualize how the oligodendrocytes function!!
