Microtubules radiate out from the Endoplasmic reticulum
Microtubules are a component of the cytoskeleton and play a crucial role in intracellular transport, cell division, and maintaining cell shape. They are not directly associated with the Endoplasmic reticulum (ER). Here is why the statement is not true:
Actin filaments in muscle bundles
- Actin filaments are indeed present in muscle bundles and are essential for muscle contraction. They work together with myosin to generate the force required for muscle movement.
Motor molecules using microtubules as tracts
- Motor molecules such as dynein and kinesin use microtubules as tracks for intracellular transport. They move organelles, vesicles, and other cellular components along microtubules to their respective destinations.
Intermediate filaments containing keratin
- Intermediate filaments are a type of cytoskeletal protein that provides structural support to the cell. They are involved in maintaining cell shape and integrity. Intermediate filaments can indeed contain keratin, which is a type of protein found in epithelial cells.
In conclusion, microtubules do not radiate out from the Endoplasmic reticulum; instead, they form a network throughout the cell and are involved in various cellular processes.

Microtubules are unbranched hollow tubules of indefinite length about 25 nm of thickness with 15 nm core and boundary formed of 13 helically arranged protofilaments of globular molecules of α and β tubulins. Microtubules grow from nucleating regions. Their tips can grow and shorten quickly.
Microfilaments are double helical cylindrical rods or filaments of actin-like protein that occur in both muscular and nonmuscular eukaryotic cells.
As microtubules do not radiate out from ER as they radiate out from the centrioles during cell division.
Microfilaments are double helical cylindrical rods or filaments of actin-like protein that occur in both muscular and nonmuscular eukaryotic cells.
As microtubules do not radiate out from ER as they radiate out from the centrioles during cell division.
So, the correct answer is option C.
