During the phase of excitation-contraction coupling of skeletal muscle, what occurs immediately after the action potential spreads down the T tubule?

The alternating contraction and relaxation of opposing layers of smooth muscle is referred to as __________.

What is the ion released from the terminal cisternae that combines with troponin and removes the blocking action of tropomyosin, resulting in the formation of cross bridges?

The type of muscle contraction in which the muscle fibers produce increased tension although the muscle neither shortens nor lengthens is called __________.

Muscle cells initiate nerve impulses.

In the sliding filament model of muscle contraction, the myofilaments slide over each other, resulting in the overlapping of actin and __________.

Which one of the following binds calcium ions in a smooth muscle, causing contraction?

When an action potential arrives at the neuromuscular junction, the most immediate result is __________.

Continued mild or partial contraction of a muscle that keeps it healthy and ready to respond is known as muscle __________.

Which of the following allows recoil of the muscle fiber when contraction ends?

The sequence of electrical changes that occurs along the sarcolemma when a muscle fiber is stimulated is known as the __________.

Myofilament cross bridges form when which two structures bond?

The refractory period in which the muscle will NOT contract if stimulated occurs during __________ of the muscle cell.

Which of the following is NOT a characteristic of skeletal muscle contraction?
