terminally differentiated cells such as neurons and muscle?

Cyclin

A patient with cancer possesses cells that are undergoing mitosis at a very rapid rate. The contractile
rings that are formed during cytokinesis are composed of

thin filaments

intermediate filaments

thick filaments

microtubules

neurofilaments - Correct Answer The answer is thin filaments. Contractile rings, composed of thin
(actin) filaments form around the site where the cleavage furrow forms during telophase. Just prior to
complete separation of the two daughter cells, the midbody forms, which is then incorporated into one
of the two cells. Intermediate filaments, thick filaments, and neurofilaments (intermediate filaments of
neurons) do not participate in the formation of contractile rings. The midbody is composed of polar
microtubules and a bridge of cytoplasm.
