Muscle

muscle

(Science: anatomy) tissue specialised for contraction. See twitch muscle, catch muscle: cardiac muscle (heart muscle) is a striated but involuntary muscle responsible for the pumping activity of the vertebrate heart. The individual muscle cells are joined through a junctional complex known as the intercalated disc and are not fused together into multinucleate structures as they are in skeletal muscle. Skeletal muscle is a rather non-specific term usually applied to the striated muscle of vertebrates that is under voluntary control. The muscle fibres are syncytial and contain myofibrils, tandem arrays of sarcomeres. Smooth muscle is muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle cells are found particularly in blood vessel walls, surrounding the intestine (especially the gizzard in birds) and in the uterus. The contractile system and its control resemble those of motile tissue cells (for example fibroblasts, leucocytes) and antibodies against smooth muscle myosin]] will cross react with myosin from tissue cells, whereas antibodies against skeletal muscle myosin will not.

Cancer = Mutation: Stopping Mutation Would Cure Cancer?

... typically, grow faster than normal cells in the body. Many cells do not actively divide in adult humans at all, these include e.g. neurons and muscle cells. Both irradiation and chemotherapy disrupt the cell cycle and thus mainly affect fast growing cells who are constantly dividing. Irradiation ...

Re:

... viruses would group up and attach via their tail fibers in order to change their density from gelatinous to a more elastic substance that mimics muscle tissue...which I'm not even sure is possible. Basically, on the micro scale you would have each individual virus grappling one another via these ...

Virus Questions [Science Fiction]

... through a virus that has a shape capable of assembling with others into a myriad of different shapes to form more elastic structures that mimic muscle tissue...but I'm unsure. Either way, if a fluid system of viruses being able to possess a communal consciousness is impossible...that tends to ...
