Cytoskeleton
About the Lecture
The lecture Cytoskeleton by Georgina Cornwall, PhD is from the course Cellular Structure.
Included Quiz Questions
Which of the following pairs are associated correctly?
- Actin: muscle contraction and cellular movements
- Microtubules: the smallest of the cytoskeletal elements
- Intermediate filaments: the largest of the cytoskeletal elements
- Actin: responsible for the movement of materials in the cell
- Microtubules: make up the main structural component of the cytoskeleton
Which of the following is NOT a function of the cytoskeleton?
- Synthesis of ribonucleic acid
- Cellular organization
- Cellular shape
- Anchoring the cell organelles
- Cellular movements
Which of the following statements is NOT correct regarding the cytoskeleton?
- Hair and nails have long chains of actin filaments associated with microtubules, which provide strength to the dead remnants of cells.
- The cytoskeleton has three main types of fibers: actin filaments, intermediate filaments, and microtubules.
- Intermediate filaments provide mechanical support and shape to cells owing to their extreme stability and toughness.
- Microtubules form channel-like structures inside cells for the quick transport of materials throughout the cell.
- Microtubules are essential in cell division as they anchor chromosomes and migrate them to opposite poles.

In my school we will take this lecture in 2 hours!!! Way too short and superficial
In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!
I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.
Needs more substance. This was barely long enough to be an introduction.
