the function of the t tubules in muscle contraction is to
transmit the action potential deep into the muscle cells
the sight where the motor nerve impulse is transmitted from the nerve endings to the skeletal muscle cell membranes are the
contraction elicited by a single brief stimulus is called
a smooth sustained contraction resulting from very rapid stimulation of the muscle in which no evidence of relaxation is seen is called
