Cytoplasmic intermediate filaments
WebNeurofilaments (NF) are classed as type IV intermediate filaments found in the cytoplasm of neurons.They are protein polymers measuring 10 nm in diameter and many micrometers in length. Together with microtubules (~25 nm) and microfilaments (7 nm), they form the neuronal cytoskeleton.They are believed to function primarily to provide structural … WebNo. Within the cytoplasm, there would still be ions and organic molecules, plus a network of protein fibers that help maintain the cell's shape, secure some organelles in specific positions, allow cytoplasm and vesicles to move within the cell, and enable cells within multicellular organisms to move. ...
