    Microscopic muscle structure:- Muscles are made up of the following components (from largest to smallest): Muscle belly Fasciculi - a group of muscle fibres that are surrounded by connective tissue Perimysium - the name given to the connective tissue that surrounds the fasciculi Epimysium - encases the muscle to hold everything together. As it nears the end of the muscle it thickens to eventually become the tendon Myofibrils - muscle fibres are made up of myofibrils and are similar to the many wires that make up a cable Sarcomere - myofibrils have many units known as sarcomeres. These are arranged end to end for the entire length of the fibre Z lines - These lines mark where one sarcomere starts and another finishes. Myofilaments - Myofibrils can be further divided into myofilaments. There are two types of myofilaments - actin (thin filaments) and myosin (thick filaments) Sarcolemma - the cell membrane that surrounds the muscle fibre Sarcoplasm contains the following: Mitochondria Myoglobin Fat, glycogen, ATP, PC Enzymes
