MICROANATOMY

Detailed explanation-1: -Microtubules help the cell keep its shape. They hold organelles in place and allow them to move around the cell, and they form the mitotic spindle during cell division.

Detailed explanation-2: -The primary types of fibers comprising the cytoskeleton are microfilaments, microtubules, and intermediate filaments. Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein.

Detailed explanation-3: -Cytoskeleton. The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move.

Detailed explanation-4: -Explanation: The cytoskeleton is made up of 3 protein filaments: actin filaments (also known as microfilaments), intermediate filaments and microtubules. The microtubules facilitate movement of vesicles between compartments.
