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.
The muscular system. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. Exceptions to this are the action of cilia, the flagellum on sperm cells, and amoeboid movement of some white blood cells. The muscular system in vertebrates consists of three different types of muscles: cardiac, skeletal and smooth.
