Malformation of the which cytoskeleton linked to an inability to contract a muscle?

The correct answer is: Microfilaments

• Malformation of microfilaments results in an inability to contract the muscles. 
• The contraction of muscles is the phenomenon that ensures the movement of these muscles. When we move our muscles, certain proteins interact that cause contraction and relaxation and help in the desired movement. 
• As we know that for this contraction, actin and myosin filaments are crucial. And actin filament being an important part of microfilaments can make sure that this process happens with ease. 
• If there would be no microfilaments present in the cytoplasm, then there will be no presence of actin too. This will cause a harmful situation where we will be unable to move our muscles. 

The actin filament slides over the myosin which causes a series of chemical reactions, resulting in the contraction of the muscles.
