GENERAL HISTOLOGY

Detailed explanation-1: -The cytoskeleton is the network of cytoplasmic protein filaments, composed of microtubules (MTs), actin filaments, and intermediate filaments, that provides an internal scaffold to give the cell shape.

Detailed explanation-2: -Definition. Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Detailed explanation-3: -The cytoskeleton is a network of protein fibers that help with cellular movement and maintaining its structure/shape. One main function of cytoskeleton is to provide mechanical support to the cell and its functions.

Detailed explanation-4: -Three major types of filaments make up the cytoskeleton: actin filaments, microtubules, and intermediate filaments. Actin filaments occur in a cell in the form of meshworks or bundles of parallel fibres; they help determine the shape of the cell and also help it adhere to the substrate.
