Fig. Muscles the motors of the body moving its various parts. Thus muscle can be defined as follows It is a contractile tissue which brings about the movements of organs and body as whole. . All the muscles of the body develop from mesenchyme except arrectores pilorum muscles of iris and myoepithelial cells of glands which develop from ectoderm. 120 General Anatomy TYPES OF MUSCLES On the basis of morphological and functional characteristics the muscles are classified into .
