separated by connective tissue. For structural reason the relative length of the cells has been somewhat reduced in the model. C . End view, showing cells in cross section 1. Capillary. The blood supply of smooth muscle is scanty compared to that of skeletal and cardiac muscle. The prominence of the vessels on the model is due to the selection of a location near a capillary junction to show the manner of branching. The capillaries appear larger in this than in the other two models because of the difference in magnification. 2. Connective tissue. Here seen between the muscle cells. This consists of elastic and reticular fibers. Its quantity varies greatly in different organs. 3. Connective tissue, seen here partly ensheathing a cell. The connective tissue actually encloses all the muscle cells throughout their length, binding them into a tissue. 4. Nucleus of a connective tissue cell. In some layers of smooth muscle connective tissue cells are either lacking or difficult to demonstrate 5. Motor end-plate of autonomic nerve fiber 6. Smooth muscle cell, cut away longitudinally to show myofibrils. A sarcolemma is lacking. 7. Nucleus of a smooth muscle cell 8. The same in transverse section 6

CARDIAC MUSCLE CELL A, B : Surface views of model from opposite sides, showing syncytial arrangement of fibers. Sarcolemma partly removed in A. Purkinje cell and three heart muscle cells cut away to level of nuclei in B. C. View of model from upper end, showing cross section of three heart muscle cells. D. Lower end of model, showing cross sections of three heart muscle cells, one passing through nucleus. 1. Cardiac m. cell, showing superficial arrangement of fibrils in B and C 2. Nucleus of Purkinje cell 3. Sarcoplasm (abundant in Purkinje cells, scant in heart muscle cells) 4. Myofibrils (evenly distributed in heart muscle cells, peripheral in Purkinje cells) 5. Nucleus of heart muscle cell 6. Intercalated discs 7. Sarcolemma 8. Area of heart muscle cell with sarcolemma removed to show myofibrils 9. Sympathetic nerve fiber 10. Nerve ending on myofibrils 11. Connective tissue, envelops all fibers and serves as a matrix for the nerves and blood vessels 12. Nucleus of a connective tissue cell 13. Longitudinal vessel of capillary network 14. Capillaries 7
