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.
It is through this connective tissue that the force generated by the individual cells is transmitted to the bone. A group of muscle cells are bundled together by collagen to form a fascicle. Since muscle cells are elongated and cylindrical, each muscle cell is usually called a muscle fiber.In skeletal muscle, the muscle fibers are very large, multinucleated, and up to several millimeters in length.he contraction of a muscle fiber is triggered by an action potential conducting over plasma membrane of the muscle fiber. The action potential conducts from the surface of the muscle fiber into the interior via transverse tubules (T tubules).
