Cytoskeletal parts, like microfilaments, microtubules, and intermediate filaments, are very important for how cells send and receive signals.

1. Microfilaments (Actin Filaments):

   • Made of actin proteins, these tiny strands are about 7 nanometers wide.
   • They help the cell change shape, which is important for how the cell responds to signals.
   • Microfilaments help cells move, which affects signals that rely on direct contact or short distances to nearby cells.

2. Microtubules:

   • These are thicker, about 25 nanometers in diameter, and they give the cell structure and support.
   • Microtubules are key for transporting materials inside the cell, including signaling molecules.
   • They also help with cell division and form the mitotic spindle, which plays a big part in how signals are sent during cell growth.

3. Intermediate Filaments:

   • These range from 8 to 12 nanometers wide and provide strength and support to the cell.
   • They help keep signaling groups in place, which makes the signaling pathways work better.

In short, the cytoskeleton is a flexible network that controls how cells respond and how they send messages important for cell communication.
