Structure And Function Of The Skeletal Muscle

STRUCTURE AND FUNCTION OF THE SKELETAL MUSCLENameInstitutionCourse Tutor DateStructure and Function of the Skeletal MuscleAs the name suggests, skeletal muscles are associated with the skeletal system. From a general perspective, each muscle, including the individual cells are covered by collagen. Collagen on the outer side of the muscle eventually merges to form tendons; cellular units that are attached to the bone. It is through the tendons that contractile force generated by the skeletal muscle is transmitted to the bone as a voluntary action. However, there are also instances of involuntary action associated with the skeletal muscle. Narrowing down to the specific units of the skeletal muscle, it is evident that a group of muscles linked together by collagen to form fascicle. Based on their elongated nature, each cell is referred to as a muscle fibre. Each muscle cell (fibre) is large, and this is exhibited by the several nuclei. Each muscle fibre is composed of contractile proteins known as the myofibrils. Within a single cross-section of the fibre, there are hundreds of myofibrils. Narrowing deeper to a single myofibril, it is segmented to
