What is the cytoskeleton
In this video I will explain what is the cytoskeleton.
What is it?
- Three-dimensional lattice proteins that serve as the backbone / sub-structure of the cell.
Features
- Cell shape
- Organize organelles within the cell
- Traffic intracellular substances
- Cellular division
- Union cells
TYPES:
1. Actin filaments (microfilaments) 3-7 nm
- Quickly polymerizes and depolymerizes
- Cell periphery
- Support, stability
2. Intermediate filaments 10 nm
- Fibrous protein grouping
- Only animal cells
- Rigidity
3. Microtubules 25 nm
- Origin: microtubule organizing center. (centrioles).
- Throughout the cytoplasm
- Functions: * Vesicle displacement and substance transport * Cell division * Internal structure of cilia and flagella.
In the video you will be able to understand better what is the cytoskeleton, what are their functions, what types are there, and we will see different examples of each one. In addition, if you are not sure you can continue practicing with problems of this type you can do the printable exercises with their solutions that I have left you on the web. We hope you learn a lot from these classes!
