Muscle fibres. Confocal light micrograph of muscle fibres. Muscle is formed from bundles of muscle fibres. Running the length of each fibre are thin threads called myofibrils. Myofibrils contain alternating bands of the proteins actin and myosin (green),which give the fibres their striped appearance. The proteins slide over each other during muscle contraction | |
