MICROANATOMY

Detailed explanation-1: -What Do Intermediate Filaments Do? Intermediate filaments come in several types, but they are generally strong and ropelike. Their functions are primarily mechanical and, as a class, intermediate filaments are less dynamic than actin filaments or microtubules.

Detailed explanation-2: -Microtubules are also highly dynamic, undergoing rapid cycles of polymerization and depolymerization in a process known as dynamic instability.

Detailed explanation-3: -Intermediate filaments are generally more stable than actin filaments or microtubules and do not exhibit the dynamic behavior associated with these other elements of the cytoskeleton (e.g., the treadmilling of actin filaments illustrated in Figure 11.4).
