It is therefore important to understand the structure and composition of muscle. In any living system there is a basic unit of life and that is cell.
Cells having similar specialized functions form together and lead to formation of organs or tissues.
Based on such specializations there are three different types of muscles in a meat animal - 1.Striated voluntary or Skeletal muscles. Striated involuntary or Cardiac muscles. 3.Smooth muscles or involuntary muscles. Fibers are long, spindle shaped.
