In an idealized cross section of normal muscle, if all muscle fibres were of equal size each fibre would conform to a hexagonal shape (Fig. 3.1), but Type 1, Type 2A and Type 2B fibres differ somewhat in their mean diameter and so there is variation not only in size, but

These disorders usually have a genetic basis, although this may not be apparent. In most patients weakness is mild or moderate, and marked wasting is unusual. These d

The metabolic myopathies result from a biochemical defect in muscle metabolism itself, the endocrine myopathies from an abnormal hormonal environment, probably affecting muscle metabolism, and the drug-induced myopathies from a direct toxic effect of the drug on

For example, in motor neuron disease there is almost always involvement of the upper motor neuron and in peripheral neuropathies sensory fibres are also involved. In this chapter only the changes seen in muscle biopsies will be described. A general
