In skeletal muscle, the role of the voltage-gated na + channel is to:
a. propagate the action potential from the neuromuscular synapse over the sarcolemma
b. open ligand-gated ionotropic channels at the neuromuscular synapse
c. provide the increase in positive charge that removes the dhp block from the ryr receptor
d. provide the positive charge that moves the tropomyosin molecule on the actin thin filament
e. a and c are correct

The correct option here is e) both a and c are correct

Explanation:

The voltage gated Na+ channel that is present in the skeletal muscle plays a very important role in both -

a) helps in initiating the action potential from the neuro muscular synapse over the sarcolemma and,

c) helps in increasing the  positive charge that removes the DHP block from the RYR receptor

These channels helps in initiating the action potential of a person and also in the propagation of the cells.
