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.
Fresh, whole flaxseed generally lasts for up to a year in an opaque, airtight container kept in the refrigerator. In the same type of container, ground flaxseed usually lasts for about six months in the freezer. You should always keep flaxseed oil in an opaque bottle and store it in the refrigerator.
