Broadly considered, human muscle—like the muscles of all vertebrates—is often divided into striated muscle, smooth muscle, and cardiac muscle. Since the vasoconstrictor fibres supplying the skin vessels are far less engaged in baroreceptor modulations than are those supplying the skeletal muscle vessels (LOFVING1961)14)there is a possibility of vasodilatation in the skin and, at the ( same time, of a vasocontriction in the skeletal muscles as long as the anaesthesia is not deep enough to depress the bulbar vasomotor centre also. In the human body, the limbs can each be divided into two segments – the upper limb can be divided into the arm and the forearm and the sectional compartments of both of these – the fascial compartments of the arm and the fascial compartments of the forearm contain an anterior and a posterior compartment.
