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.
How Long does Fresh Salmon Last in the Fridge? Salmon can be kept fresh in your refrigerator for up to two days. As soon as you bring your salmon home, unwrap it and wipe it down with a damp towel then wrap it in plastic wrap and place it in the coldest area of your refrigerator.
