what does a myofibril do? -72.40.25.206
"The photo below is a high power picture (electron micrograph) of a small region of a skeletal muscle cell."
I attempted to explain the difference here, could someone go further into what we know about the difference in how the forces at action in contraction work during an eccentric movement? The heads don't move together, yet there is a force attempting to do so, right? Dictabeard (talk) 10:06, 28 January 2011 (UTC)Reply
The cited reference is an atlas, which would typically only provide diagrams and pictures. A complete definition of myofibrils should include information about the physiology (the function), in addition to the structure. While the information provided in the article is accurate, I think it needs to be expanded to include recent research of the topic and a more comprehensive definition.

The following explanation is wrong: "These Z-discs are dense protein discs that do not easily allow the passage of light. The T-tubule is present in this area. The area between the Z-discs is further divided into two lighter colored bands at either end called the I-bands, and a darker, grayish band in the middle called the A band.
The I bands appear lighter because these regions of the sarcomere mainly contain the thin actin filaments, whose smaller diameter allows the passage of light between them. The A band, on the other hand, contains mostly myosin filaments whose larger diameter restricts the passage of light. A stands for anisotropic and I for isotropic, referring to the optical properties of living muscle as demonstrated with polarized light microscopy."
This has nothing to do with light!!! All pictures about the sarcomere are made with electron microscopy... there is no possibility to observe proteins like actin with light microscopy.

Sarcostyle redirects here, but the word is not mentioned in the article. Is it just an old word for a Myofbril? Or a part of it? Would be great if somebody could add this. I came across the word in a text from the 1930ies and wonder what it is. Dietzel65 (talk) 17:27, 7 January 2021 (UTC)Reply
