The fine structure of the muscle-tendon junction in the rabbit

Ultra-estrutura da junçäo músculo-tendínea em diafragma de coelho. Os autores estudam, no presente trabalho, a ultra-estrutura da junçäo músculo-tendínea do diafragma de coelho. Na extremidade da fibra muscular, o sarcolema apresenta várias fendas e invaginaçöes como dedos de luva. As fibrilas colágenas do tendäo säo sinuosas e estäo inseridas obliquamente na superfície externa da lâmina basal do sarcolema. Esta disposiçäo parece estar relacionada ao mecanismo de transmissäo de tensäo. Na extremidade da fibra muscular, miofibrilas ramificam-se e prendem-se no sarcolema

The fine structure of the myo-tenden junction is studied in the diaphragm muscle of the rabbit. At the termination of the muscle fiber, the sarcolemma is thrown into a series of clefts and finger-like invagination. The collagen fibrilis of the tendon are sinnous and are inserted obliquely into the outer surface of the basal lamina of the sarcolemma. This structure appears to be related to the mechanism of transmission of tension. Myofibrilis branch over the sarcolemma (AU)n into a series of clefts and finger-like invagination.
