Describe the organization of skeletal muscles (4)

FASCICLES: made of tightly muscular bundles (fascicles) surrounded by connective tissue (perimysium) MUSCLE FIBRES: Each bundle contains multiple muscle fibres formed from fused muscle cells (multinucleated) MYOFIBRILS: muscle fibres are made up of myofibrils which are responsible for contraction SARCOMERES: myofibrils divide into repeating sections called sarcomeres
