Definition:Muscle tissue which is unstriated, composed primarily of smooth muscle fibers surrounded by a reticulum of collagen and elastic fibers. Smooth muscle 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[GO].
Comment:[homology-note] "(...) the first bilateral animals possessed only smooth muscles with the molecular repertoire necessary to build a striated muscle. (...) it is more parsimonious to regard striated muscle cells as a sister cell type to the smooth muscle cells. In this scenario, striated and smooth muscles would have arisen in the stem lineage that led to the Nephrozoa (i.e. all Bilateria exclusive the acoelomorphs) (Hejnol et al., 2009), from an 'acoel-like' smooth muscle, by segregation and divergence of functions and through differential recruitment of additional genes[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0001246", ontology="VHOG", source="DOI:10.1002/jez.b.21416 Chiodin M, Achatz JG, Wanninger A, Martinez P, Molecular architecture of muscles in an acoel and its evolutionary implications. Journal of Experimental Zoology (2011)", source="http://bgee.unil.ch/"}; [terminology-note] "GO uses visceral and smooth interchangeably. However visceral can also be used in the sense of the viscera. Many fly annotations to smooth muscle terms. If we want to be inclusive of insects have to have a general definition of tissue that includes cells."
