Which Cell Types Have High Density of Cytoplasmic Intermediate Filaments?

In summary, the types of cells that would contain a high density of cytoplasmic intermediate filaments are nerve cells in the spinal cord of a mouse and human skin epithelial cells, as these cells need the filaments to maintain their structure and rigidity.

Which of the following types of cells would you expect to contain a high density of cytoplasmic intermediate filaments?

A) Free living amoeba (the answer is no, but why? Is it because the amoeba has to move)

B) Human skin epithelial cell

C) smooth cell in the digestive tract of a vertebrate

D) Nerve cell in the spinal cord of a mouse

E) Human sperm cell

F) Plant cell

Any help would be appreciated :smile:

First, the cytoplasmic intermediate filaments has only been isolated in on type of cell and this would help eliminate two choice.

Second, ask yourself what is the role of the cytoplasmic intermediate filaments.

Based on their function what cell type needs this function the most. That should eliminate two more choice.

The answer is bit more difficult to find. You may find what you want in the chapter.

INtermediate filaments function as tension-bearing elements to help maintain cell shape and rigidity, and serve to anchor in place several organelles, including the nucleus and desmosomes

Ok if this is true then wouldn't a nerve cell in the spinal cord of a mouse need the filaments to maintain the structure and rigidity of the cell.

Also human skin epithelial cell would need the filaments to maintain structure of human skin
 

Related to Which Cell Types Have High Density of Cytoplasmic Intermediate Filaments?

1. What are cytoplasmic intermediate filaments?

Cytoplasmic intermediate filaments are a type of structural protein found in the cytoplasm of cells. They provide mechanical support and help maintain the shape of the cell.

2. Which cell types have a high density of cytoplasmic intermediate filaments?

Cell types that require a lot of structural support, such as muscle cells and nerve cells, tend to have a high density of cytoplasmic intermediate filaments.

3. How do cytoplasmic intermediate filaments differ from other types of cytoskeletal filaments?

Cytoplasmic intermediate filaments are thicker and more stable than microfilaments (actin filaments) and microtubules. They are also less dynamic and do not participate in cell movement like the other two types of filaments.

4. What is the function of cytoplasmic intermediate filaments?

In addition to providing structural support, cytoplasmic intermediate filaments also play a role in cell signaling, cell division, and protection against mechanical stress.

5. How are cytoplasmic intermediate filaments formed?

Cytoplasmic intermediate filaments are made up of different proteins called intermediate filament proteins. These proteins form long, twisted fibers that make up the filaments. Different types of intermediate filament proteins are found in different cell types, resulting in the formation of various types of cytoplasmic intermediate filaments.
