Label each statement regarding skeletal muscle contraction as true or false:
T-tubules carry the action potential of a skeletal muscle from its exterior to its interior. ◻ During skeletal muscle contraction, in order to shorten sarcomeres, the thin and thick filaments fold into tighter, smaller shapes.
◻
In skeletal muscle contraction, calcium binding to troponin is the step responsible for "coupling" excitation to contraction.
◻
A higher frequency of action potentials from a motor neuron will lead to summation of skeletal muscle twitches.
