Skeletal muscle is made up of elongated cylindrical multinucleate cells, also called muscle fibers, that span the length of the muscle. Each muscle cells is surrounded by connective tissue called endomysium. Endomysium is similar in composition to basement membrane that underlies epithelia.

So let’s start with the basic unit of a muscle cell. You have the sarcolemma which is the cell membrane, and you have the sarcoplasm which is essentially the muscle cell cytoplasm. Then you have this thing called the myofibril which is the contractile unit of skeletal muscle.

Some muscles (skeletal muscles) will not contract unless stimulated by neurons; other Myofibrils are contractile units that consist of an ordered arrangement of 24 Sep 2008 The same axon may also innervate other muscle fibers. All the fibers innervated by the same axon are called a motor unit. Motor units are small, The skeletal muscle cells are organized from contractile units know as sarcomeres, which are the structural subunits arranged in a repeated pattern, along the The sarcomere is the functional unit of a skeletal muscle cell.

Describe the mechanical properties of muscle that are characterized by the length-tension relationship and the force-velocity relationship. Myofibrils are the thin fibers made up of acti9n and myosin filaments and are present among the cytoplasm of skeletal muscle fibers. They are the contractile units that are responsible for the contraction of skeletal muscles. Each skeletal muscle fiber is innervated by a separate axon and can undergo contraction independent of other cells. As the smallest contractile unit of a muscle, a sarcomere is an important unit in a skeletal muscle. It is one of the basic structure in almost all types of muscles.
