概要

論文の詳細を見る
This study was designed to investigate the ultrastructure of the human thyreoarytenoid muscle using both scanning and transmission electron microscopes. The specimens were prepared by the A-O-D-O method for SEM and by the ordinary method for TEM.Mitochondria vary in shape such as long, L-shaped, U-shaped or globular. Long mitochondria were observed along the myofibrils, while the globular ones were distributed under the sarcolemma. Observing by SEM, sarcoplasmic reticulum showed network-structures and formed the terminal cisterna, which were connected each other over the transverse tubules.Intracellular structures such as mitochondria, sarcoplasmic reticulum, myofibrils, could be observed by TEM. However, the stereoscopic image cannot be obtained by TEM. The A-O-D-O method made it possible to observe intracellular structures three-dimensionally using SEM. Therefore, SEM is as useful as TEM for studying the pathological changes of the laryngeal muscles.
