Cytoskeleton.
Cytoskeleton
the microscopic nerve fibers are called chemocytes
All cells, except those of most bacteria, contain components of the cytoskeleton. They help the cell remain rigid but also help it move and change its shape when instructed to do so. Components of the cytoskeleton also enable cilia, flagella and sperm to move, cell organelles to be moved and positioned, and muscles to function. During cell division these components also assist by pulling the daughter chromosomes to opposite ‘poles’ in the dividing process. Throughout the life of the cell various molecules and cargo containing vesicles are transported around the cell by motor proteins. These move along the protein filaments using them as rail road tracts rather like a railway locomotive runs on.
The solid protein fibers, which form a mesh over wounds, are called "fibrin".
Collagen
its cytoskeleton.
Long fibers of DNA and protein are called chromatin. Chromatin is the material that makes up chromosomes in eukaryotic cells and is composed of DNA wrapped around histone proteins.
The meshlike network of protein fibers that supports the shape of the cell is either cellulose (cell wall) or the cytoskeleton (inside).
microtubules
elastic fibers
All three forms of ALX are unified by the presence of Rosenthal fibers (RF), microscopic protein aggregates that are found in astrocytes in the brain and spinal cord.
These are called kinetochore fibers. They are microtubules that attach to the kinetochore, a protein structure on the centromere of the chromosome, helping to move the chromosomes during cell division.
