Muscles in Culture
A analysis of why muscle fibres being cultured for study in the lab deteriorate finds it's due to changes induced in the cell's inner scaffold or cytoskeleton and that keeping the cells in a fibrin-based hydrogel improves their viability

I just described the cytoskeleton as 'cell bones' fml
All of the above motors have separate head, neck, and tail domains, as does myosin XI (Figure 1.27). (...) The tail domain usually contains coiled-coil regions for dimerization, and the end of the globular tail domain binds to specific organelles or "cargo" and is called the cargo domain (see Figure 1.27B). (...) The two heads of the dimer then alternately bind to the cytoskeleton and "walk" forward while the neck flexes as ATP is hydrolyzed (see Figure 1.27C).

I'm still here (I don't have friends...or a life): @barelyacademia
so in ap bio we did a cell organelle speed dating thing, where each of us was an organelle and we had to interview each other on our jobs (functions), hang-out places (prokaryotic/eukaryotic, animal/plant), fun facts, etc. so instead of reviewing the actual info that’s gonna be on our test, I learned that:
- the cell membrane is a workaholic while the chloroplast sunbathes all day, so they’re not exactly compatible
- the cell wall is very protective, which...<3
- but it also has a drinking problem, so :/
- the cytoskeleton can casually start disease when it has an off day
- the plasma membrane has DID
- the chloroplast and the mitochondria have a rivalry, but the rough ER and the ribosomes are best buddies
- the nucleus wants to form a threesome
- and the cilia has the most concerning pick-up lines
basically, the point was that I could totally write a fic about cell organelles, but that would take too much work

Cytoskeleton

Hello Everyone!
When I was first introduced to the cytoskeleton content last year most of it went in one ear and out the other. It was such a painful topic to learn about but now that I’ve been retaught it in a new way it’s not so bad!
Happy Studying!
