Contraction of these deep core muscles provides segmental stabilisation of the spine. The outer unit consists of many muscles such as the Obliquus externus, Obliquus internus, Erector spinae, Latissimus dorsi, Gluteus muscles, the Quadratus lumborum, adductors and hamstrings.
Each muscle fiber is multinucleated cylindrical cell containing groups of myofibrils. The myofibrils are in turn made up of myofilaments of three types namely actin, myosin, and tropomyosin.
