THE CYTOSKELETON - MICROTUBULES, INTERMEDIATE FILAMENTS, MICROFILAMENTS

The cytoskeleton of a eukaryote - specifically of an animal cell, has three kinds of cytoskeletal filaments, which provide structure, aid in movement, and help with transport within the cell. Microtubules organize the positions of organelles and direct intracellular transport. Intermediate filaments are rope-like fibers found along the inner face of the nuclear envelope, and they also build cable networks connecting the cells of epithelial sheets. These filaments provide mechanical strength. Microfilaments, or actin filaments, are most concentrated right beneath the plasma membrane, at the so-called “cortex” of the cell, and they control the outer shape of the cell and are important in locomotion. Actin can form several kinds of cell surface projections, including microvilli, lamellipodia, and filopodia. These help move cells over solid substrates.
The three kinds of cytoskeleton filaments work in concert with countless accessary proteins, which attach the filaments to each other and to other cell components and direct their assembly, distribution, and disassembly. The cytoskeleton is not a static structure, but is dynamic, able to change or persist to suit the cell’s needs. This is because the cytoskeletal structures are composed of tiny polar subunits that can rapidly assemble and disassemble thanks to weak, noncovalent linkages into “polymers”. These macromolecular components of the cytoskeleton filaments are constantly in flux.

This is a very good resource. Many thanks! It's also very good you haven't gone down the "edutainment" route, which mostly end up dumbing down the subject so much, or distracting so much, that you learn nothing at all. Biology really needs to be taught visually, especially with movement, because there are so many proceses involved. I think you guys have found the sweet spot between information and animation.

[@NeuralAcademy]

Thank you so much! :-D My aim is indeed to present as much info as possible while still keeping the videos fun and visually informative. Glad to be successful ^_^

[@tcfraser237]

These videos are among the best educational resources on the internet. Great animations throughout!

[@xoliswasokhela3627]

This work is brilliantly arranged , I just had to subscribe

[@natekat7238]

This really help meee! The ilustrations are amazing.GOOD JOB😆

[@NeuralAcademy]

I'm so glad to have helped!! :-D

[@user-cu8vc3qn4z]

Thank you. You were comprehensive without being confusing!

[@claudiasunshinetristancho5595]

thank you! A lot of good and in-depth explanations with the visuals 👍. I was able to follow although the pace was a bit fast. Good for my personal research.

[@lakshmimenon2804]

Thank you for this

[@lefterisxaleplis1174]

thanks a lot amazing video also this animation type of videos make me understand better to be honest if someone didn't understand cytoskeleton staff, function and in general how it works I recommended for sure

[@kumquats2842]

the best video ive come across for MTs. thank you

[@arashhunter]

thank you. comparatives is very good

[@davidschmid6963]

beautiful illustrations!

[@rogsang9764]

this is a masterpiece

[@niloofarkh4779]

perfect please keep up the good work

[@Techience]

You guys really need to make an Instagram/Twitter

[@NeuralAcademy]

Definitely something we'll do sometime soon!

[@andersnelson6464]

I am an engineer why am I watching this

[@the81kid]

This really helps!

[@janieli]

great video!! i was just wondering what it meant by nucleation?

[@sundew_36]

super amazing.... thanks alot

[@maryjoydatoy91]

This is so amazing!!!!

[@sophieshelley110]

this kinda gives the wrong information! for example it says how the micro tubles keeps the organelle positions when it is actually more the role of the intermediate filaments. unless this is right and my course is telling me something completely different.

[@kashishkumari9372]

👍👍

[@gracebayan6914]

I thought of it as the scaffolding

[@needy.00]

Omg bless u guys

[@needy.00]

But what does nucleate mean °^°

[@sanjaykumar-pw3oo]

👍

[@vanshmohanjha3452]

Sir what is the difference between cytosol and cytoplasm

[@nehabheemar9534]

cytoplasm is plural of cytosol

[@robindcole]

Cytoplasm is everything contained within the cell, including organelles. Cytosol is exclusively the fluid component of cytoplasm.

[@tofusuns896]

Is cytoskeleton considered an organelle?

[@bramkayser445]

Yes. Important to know it doesn't have a membrane. It is a proteinvessel.

[@SakurabaAyane]

The audio makes me super sleepy. I can't keep my attention for more than 2 min... the video seems well made otherwise. (:

[@mclee0905]

haha same

[@djtim06]

Indeed, I can't listen to such monotone voice-overs

[@lionandthecobra1]

[@FuckenMoonFace]

so fast and too much information

[@rojaslopezbernardo86]

too much info
