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.
Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis. Muscle fibres are cylindrical, and multinucleated.keletal muscle is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system.
