SEM 観察では,T細管は筋節の幅に一致した一定の間隔で細胞膜から内方へ陥入し,細胞に対して垂直方向に走り,Z線レベルで筋原線維の表面を横切り,細胞の中心部へ向かっていた.T細管の分岐,または縦細管は認められなかった., Bovine ventricular myocardium was observed by transnission (TEM) and scanning electron microscopy (SEM). By TEM observation, the transverse (T) tubules could be easily identified owing to their continuity with the cell membrane, relatively large diameter, retention of amorphous cell coat material in the lumina and their running transversely to Z-line levels of adjacent myofibrils. By SEM observation, T tubules were noted to invaginate inward from the cell membrane at constant intervals consistent with sarcomere length, run perpendicular to the cells and cross the surface of the myofibrils at the Z-line levels to the central region of the cells. Longitudinal tubules or branches of the T tubules could not be detected in the present SEM observations.}, pages = {33--37}, title = {ウシ心筋の横細管について}, volume = {35}, year = {1988}, yomi = {クロキ, マサコ} }
