Florida - Agriculture. Florida's most important agricultural products, and the ones for which it is most famous, are its citrus fruits. Florida continues to supply the vast majority of orange juice consumed in the US. Florida produced nearly 80% of the nation's oranges and 79% of its grapefruits in 2002.
The cell membrane of a muscle cell is called the sarcolemma, and this membrane, like that of neurons, maintains a membrane potential. So, impulses travel along muscle cell membranes just as they do along nerve cell membranes. However, the 'function' of impulses in muscle cells is to bring about contraction.undreds or thousands of muscle fibers (cells) bundle together to make up an individual skeletal muscle. Muscle cells are long, cylindrical structures that are bound by a plasma membrane (the sarcolemma) and an overlying basal lamina and when grouped into bundles (fascicles) they make up muscle.
The minireview in this and the following issues updates our understanding of the structure and function of the basement membrane, cytoskeletal costameres, and the major trans-sarcolemma links (integrins and dystroglycan) in skeletal muscle. The basement membrane surrounds skeletal muscle fibers and is now known to be critical in muscle fiber structure and function. The skeletal muscle basement membrane is composed of the basal lamina and the reticular lamina. Basal lamina is directly linked to the sarcolemma.
