- Front
- Back
|
The ability of muscle to shorten forcefully.
|
Contractility
|
|
|
The capacity of muscle to respond to a stimulus.
|
Excitability
|
|
|
The ability of a muscle to be stretched beyond its normal resting length and still have the ability to contract.
|
Extensibility
|
|
|
The ability of muscle to recoil to its original resting length after it has been stretched.
|
Elasticity
|
|
|
Comprises about 40% of the body's weight and is responsible for locomotion, facial expressions, posture, respiratory movements, and other body movements. Under voluntary control.
|
Skeletal Muscle Tissue
|
|
|
Most widely distributed muscle tissue in the body with the greatest variety of functions. It is found in the walls of hollow organs and tubes, the interior of the eye, the walls of blood vessels, and other locations. Under involuntary control.
|
Smooth Muscle Tissue
|
|
|
This muscle tissue is unique in that it demonstrates autorhythmicity and is involuntarily controlled by the endocrine system and the autonomic nervous system.
|
Cardiac Muscle Tissue
|
|
|
A single, long, cylindrical cell containing several peripherally located nuclei.
|
Skeletal Muscle Fiber (Skeletal Muscle Cell)
|
|
|
The characteristic of skeletal and cardiac muscle tissue to have alternating light and dark striped appearance.
|
Striated
|
|
|
This material is critical to the proper functioning of skeletal muscle. It provides muscle fibers with a solid structure to which they attach.
|
Connective Tissue
|
|
|
The plasma membrane of a single muscle fiber.
|
Sarcolemma
|
|
|
The thick layer of connective tissue found just outside the sarcolemma of a skeletal muscle fiber.
|
Endomysium
|
|
|
The heavy connective tissue layer that bundles muscles fibers together. It is found outside the endomysium.
|
Perimysium
|
|
|
A bundle of muscle fibers held together by perimysium.
|
Fasciculus
|
|
|
The third and outermost layer of connective tissue which bundles many fasciculi together and which covers the entire surface of the muscle.
|
Epimysium
|
|
|
The general term for connective tissue sheets within the body.
|
Fascia
|
|
|
Once known as deep fascia, this forms the connective tissue sheets which separates and compartmentalizes individual muscles or groups of muscles.
|
Muscular Fascia
|
|
|
The type of neurons that stimulate muscles to contract.
|
Motor Neurons
|
|
|
The cytoplasm of a skeletal muscle cell.
|
Sarcoplasm
|
|
|
A threadlike structure approximately 1 - 3 um in diameter that extends from one end of the muscle fiber to the other.
|
Myofibrils
|
