Muscle fatigue is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.]]> 2018-10-25 17:08:24 UTC https://padlet.com/kait0990/z34tm6z93llg/wish/297072282 kait0990 https://padlet.com/kait0990/z34tm6z93llg/wish/297072492 Muscle spasm is an involuntary contraction of a muscle that can cause a great deal of pain.

Because actin is tethered to structures located at the lateral ends of each sarcomere called z discs or "z bands," any shortening of the actin filament length would result in a shortening of the sarcomere and thus the muscle. This theory has remained impressively intact ]]> 2018-10-25 17:10:32 UTC https://padlet.com/kait0990/z34tm6z93llg/wish/297073560 kait0990 https://padlet.com/kait0990/z34tm6z93llg/wish/297073814 Actin is a spherical protein that forms filaments, which are involved in muscle contraction and other important cellular processes.
