Each skeletal muscle consists of two kinds of tissue: connective tissue, and muscle tissue
Connective tissue of skeletal muscle contains:

Layers of connective tissue
Tendon, and sometimes aponeurosis
The layers of connective tissue have a major role in protection and covering of muscle fibers, muscle fascicles, and an entire skeletal muscle. Tendons attach the skeletal muscles to bones. Aponeurosis is structurally as tendon that connects the muscles together, or to bon

the two divisions: the sympathetic division and the parasympathetic division

the left, is the emergency system. It prepares the body to put out energy and to protect it from effects of injury. It shuts the gut down, speeds up the heart, increases blood pressure, dilates (makes bigger) the pupils of the eyes, makes more glucose (blood sugar) available in the blood for energy, etc. Cannon described these reactions as preparation for fight or flight (running away).

The parasympathetic division, , is the "housekeeping" division. It acts to replace and recover from the activities of living. Its action is (almost always) the opposite of the sympathetic division. It activates the gut for digestion, slows the heart rate, decreases the blood pressure, etc.
