a microscopic contractile filament of STRIATED MUSCLE, made up of a series of SARCOMERES. The myofibril is made up of numerous longitudinal filaments of two forms, thick (MYOSIN) and thin (ACTIN). See MUSCLE, I-BAND. Relatively little is known of the contraction of smooth muscle, where contractile elementsâ are thought to contain both actin and myosin.
Posted April 25 2011 - 3:53 PM. How long will a whole fish (with guts and everything) last in the fridge? About 3 days, depending on the size and type of fish.......smaller fish, shorter time..... I have kept a whole un-gutted bass on ice in a cooler for 4 days with no issues. SOL Member #174.
