Microfilaments, also known as actin filaments, are similar to microtubules in that they are protein filaments that are part of the cytoskeleton in cells. They are involved in cell structure, support, and movement.
Bacteria do not have microtubules in an eukaryotic sense since they do not have tubulin. However, they do have tubulin homologue FtsZ protein that form structures and perform functions similar to microtubules in eukaryotes. Sometimes these structures are referred to as 'bacteria microtubules'.
Yes, spindle fibers and microtubules are essentially the same in that spindle fibers are composed of microtubules. Microtubules are a component of the cytoskeleton, made of tubulin protein subunits, and they play various roles in cellular structure and transport. During cell division, specifically in mitosis and meiosis, microtubules organize into spindle fibers that help separate chromosomes. Thus, while all spindle fibers are microtubules, not all microtubules function as spindle fibers.
Microtubules
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.

The microtubules can be compared to your bones because they provide shape for the cell.
Cilia, which are similar to flagella in structure, would also show the same pattern of microtubules. Both flagella and cilia contain a 9+2 arrangement of microtubules, with nine outer doublet microtubules and a central pair of microtubules.
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
Like bones, microtubules provide a rigid structure for the cell so it is not a shapeless blob.

The Cytoskeleton is a system of microtubules, in a cell.

The bones of a lion have the same names as the bones of a domestic cat, which are very similar to a human's bones. A comprehensive list is not possible in this forum.
