POTENCIAL DE ACCIÓN MUSCULAR

Los tú bulos transversos son extensiones internas de la memnerviosas
mielinizadas grandes que excitan al músculo esquelético

Los túbulos transversos (túbulos T) siguen un trayecto transversal a
las miofibrillas. Comienzan en la membrana celular y penetran desde
un lado de la fibra muscular hasta el lado opuesto. En el punto en que
los túbulos T

La conducción de los potenciales de acción en las fibras nerviosas es
cualitativamente similar, pero no cuantitativamente similar a la de las
fibras musculares esqueléticas. Algunas de las diferencias y
similitudes cuantitativas son las siguientes:

El potencial de membrana en reposo es aproximadamente de -80 a -
90 mV en las fibras esqueléticas, similar al de las fibras nerviosas
mielinizadas grandes.

La duración del potencial de acción es de 1 a 5 ms en el músculo
esquelético, aproximadamente cinco veces mayor que en los nervios
mielinizados grandes.

La velocidad de conducción es de 3 a 5 mis, aproximadamente 1/18
de la velocidad de conducción de las fibras
