Muscle-tendon elasticity complex is the natural ability of your musculoskeletal system to 'return to its original state'. When the limb of your body is moved in any way in any direction for any purpose, musclesand tendons accommodate by elongating or shortening at various key spots.

All muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten. ... Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.

Contractility refers to the ability for self-contraction, especially of the muscles, or similar active biological tissue: Muscle contraction · Myocardial contractility . All muscle cells share several properties: contractility, excitability, extensibility, and elasticity: Contractility is the ability of muscle cells to forcefully shorten. ... Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.

Upon nervous system excitation for a contraction, calcium is released into the fiber. It binds with troponin and stimulates it to move tropomyosin, exposing the binding site for the myosin crossbridge. Because of the presence of calcium, your musclecan now contract.

Myosins are a superfamily of motor proteins . they are best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP-dependent and responsible for actin-based motility.

Actin is a family of globular multi-functional proteins that form microfilaments. It is found in essentially all eukaryotic cells . this where it may be present at a concentration of over 100 μM; its mass is roughly 42-kDa, with a diameter of 4 to 7 nm.

The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement . According to the sliding filament theory, Overlapping actin and myosin (thick) filaments of muscle fibers slide past the actin (thin) filaments during muscle contraction . while the two groups of filaments remain at relatively constant length

Skeletal muscle is one of three major muscle types, the others being cardiac muscle and smooth muscle. It is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.

Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscles . with the other two being skeletal and smooth muscles. It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.

Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically. It constitutes much of the musculature of internal organs and the digestive system. smooth muscleSmooth muscle cells. Polarlys. smooth muscleThe stomach is composed of smooth muscle cells.

a condition marked by intermittent muscular spasms, caused by malfunction of the parathyroid glands and a consequent deficiency of calcium.Tetany can also be caused by magnesium deficiency or too little potassium. ... This can lead to dramatically lowered calcium levels, which can trigger tetany.

Spores of the bacteria that cause tetanus, Clostridium tetani, are found in soil, dust and animal feces. When they enter a deep flesh wound, spores grow into bacteria that can produce a powerful toxin, tetanospasmin, which impairs the nerves that control your muscles (motor neurons).

Clonic spasms refer to alternating involuntary muscular contraction and relaxation in quick succession. Tonic spasms are rigid muscle contractions that last a period of time. both are different types of spasms .

# data[].attributes.body
A spasm is a sudden involuntary contraction of a muscle, a group of muscles, or a hollow organ such as the heart. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain.

Muscle fatigue is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise . abnormal fatigue may be caused by barriers to or interference with the different stages of musclecontraction .

The main function of the muscular system is movement. Musclesare the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the functionof movement is the muscular system's second function: the maintenance of posture and body position.

A fascia (/ˈfæʃ(i)ə/; plural fasciae /ˈfæʃii/; adjective fascial; from Latin: "band") is a band or sheet of connective tissue . it is primarily collagen . it is found beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs

A tendon or sinew is a tough band of fibrous connective tissue . they usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body.
