Solution:

Structure of a skeletal muscle - Each skeletal muscle in is made of a number of muscle bundles (or fascicles) that are held together by a common fascia (collagenous connective tissue). Each muscle bundle is made up of a number of muscle fibres. Each muscle fibre is covered by a plasma membrane, known as sarcolemma. A muscle fibre is an anatomical unit of muscle. A muscle fibre is a syncytium (multinucleated condition) and is having cytoplasm (sarcoplasm), endoplasmic reticulum (sarcoplasmic reticulum - a storehouse of calcium ions) and a large number of parallelly arranged filaments in the sarcoplasm - myofilaments or myofibrils.
