Understand that the cytoskeleton in eukaryotic cells is composed of three main types of protein filaments: microfilaments, intermediate filaments, and microtubules.
Recall that microfilaments are made of actin and are involved in cell shape and movement.
Recognize that intermediate filaments provide mechanical support and help maintain cell integrity.
Know that microtubules are hollow tubes made of tubulin that help with cell shape, intracellular transport, and chromosome movement during cell division.
Identify that tight junctions are not part of the cytoskeleton; instead, they are structures involved in cell-cell adhesion and creating a barrier between cells.
