The epimysium also separates muscle from other tissues and organs in the area, allowing the muscle to move independently. Inside each skeletal muscle, muscle fibers are organized into individual bundles, each called a fascicle, by a middle layer of connective tissue called the perimysium. This fascicular organization is common in muscles of the

Excitation-contraction coupling. Although the term excitation-contraction coupling confuses or scares some students, it comes down to this: for a skeletal muscle fiber to contract, its membrane must first be "excited"—in other words, it must be stimulated to fire an action potential. The muscle fiber action potential, which sweeps along the sarcolemma as a wave, is "coupled" to

6 FAQs about [Muscle energy storage principles include]

Why is elastic energy storage important in muscle and tendon?

Elastic energy storage in muscle and tendon is important in at least three contexts (i) metabolic energy savings derived from reduced muscle work, (ii) amplification of muscle-tendon power during jumping, and (iii) stabilization of muscle-tendon force transmission for control of movement.

What is muscle and tendon energy storage?

Muscle and tendon energy storage represents the strain energy that is stored within a muscle-tendon complex as a muscle and tendon are stretched by the force developed by the muscle when it contracts. This energy may be subsequently recovered elastically when the muscle relaxes.

Why is elastic energy stored within a muscle when it contracts?

Elastic energy that can be stored within a muscle when it contracts is generally associated with its passive force-length properties, because these depend on the amount of non-contractile connective tissue within the muscle.

Do parallel-fibered muscles have elastic energy storage?

For parallel-fibered muscles that have little or no tendon in series with the muscle's fibers, elastic energy storage is limited to parallel and series elastic elements within the muscle, which include the cross-bridges themselves.

How is energy stored in biological materials?

For pure elastic elements, all of the energy that is stored during loading is returned during unloading. However, most biological materials are non-linearly elastic and exhibit some degree of inelastic or viscous energy dissipation, which is ultimately lost as heat (Fig. 1c ). Muscle and Tendon Energy Storage. Figure 1

What energy is needed for muscle activity?

Energy drawn from high-energy phosphate bonds is needed for muscle activity. The cell stores a small amount of ATP near the contractile proteins . The use of this ATP is not dependent on a supply of oxygen, and, therefore, the energy is available as soon as the muscle requires it.
