A microfilament can be found in the cytoskeleton. In the neuron, microfilaments are 5 nm in diameter and are braids of 2 actin molecules. Actin proteins are the most abdundant proteins in all cell types. They are involved in the mechanism, of muscle contraction. The assembly and dissembly of microtubules is regulated by signals in the nuron.
Microtubules run longitudinally down the core of the neurites. They are attached to the membrane by a meshwork of fibrous proteins lining the inside of the membrane similar to a spider web.

Microfilaments are well known for their role in what?
Microfilaments are well known for their role in cell movement and shape changes, such as in cell division, muscle contraction, and cell migration. They are also involved in maintaining cell structure and providing mechanical support.
What two parts make up the cytoskleton?
The cytoskeleton is composed of microfilaments (actin filaments) and microtubules. These components provide structure and support to cells, as well as playing a role in cell movement and intracellular transport.
What is the role of microfilaments is cell division?
They Split The Cel During Cytokinesis
what is the role of microfilaments?
Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
The cytoskeleton helps give a cell shape What structures plays this role?
Microfilaments and microtubules
What is the main function of microfilaments?
Microfilaments are responsible for providing structural support and maintaining cell shape. They also play a key role in cell movement, such as muscle contraction and cell division. Additionally, microfilaments are involved in intracellular transport and cellular signaling.
Why is microfilaments important?
Microfilaments are important because they play a key role in cell structure and movement. They are involved in maintaining cell shape, cell division, and cell migration. Microfilaments are also crucial for various cellular processes such as muscle contraction and cell signaling.
What is the role microfilaments in call division?
Microfilaments, primarily composed of actin, play a crucial role in cell division by facilitating cytokinesis, the final stage of mitosis. During this process, microfilaments form a contractile ring at the cell's equator, which constricts and ultimately divides the cytoplasm into two daughter cells. This action helps ensure that each new cell receives an appropriate share of cellular components. Additionally, microfilaments contribute to the overall shape and mechanical stability of the dividing cell.
Long threads made of actin?
Microfilaments.
What are the tiny strands called that are in a cell?
Microfilaments
What is the role of microfilaments incell division?
Microfilaments and microtubules that make up the cytoskeleton in the cell move/push the chromosomes and organelles into place for the various phases of cell division. (in metaphase, for example, they are moved to the metaphase plate (the center of the cell)) The organelles don't just randomly think "I think I'll move now." So I guess that would be the main role of microfilaments in cell division. :-)
What roles of microfilaments in cell division?
During cytokinesis the microfilaments form a contractile ring around the plasma membrane. The ring of filaments is equidistant from the two spindle poles, and it contracts eventually pinching the cell in two.
