stiffening of the joints and muscles of a body a few hours after death, usually lasting from one to four days

The heart automaticity is a fundamental physiological function in higher organisms.

Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormones

Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.

# data[].attributes.body
Extensibility is the ability of a muscle to be stretched. For instance, let's reconsider our elbow flexing motion we discussed earlier. In order to be able to flex the elbow, the elbow extensor muscles must extend in order to allow flexion to occur. Lack of extensibility is known as spasticity.

Contractility is the ability of muscle cells to forcefully shorten.

# data[].attributes.body
Because of the presence of calcium, your muscles can now contract.

# data[].attributes.body
a fibrous protein that forms (together with actin) the contractile filaments of muscle cells and is also involved in motion in other types of cells.

# data[].attributes.body
The sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement

# data[].attributes.body
It is a form of striated muscle tissue, which is under the voluntary control of the somatic nervous system.

# data[].attributes.body
another term for myocardium.

# data[].attributes.body
muscle tissue in which the contractile fibrils are not highly ordered, occurring in the gut and other internal organs and not under voluntary control.

# data[].attributes.body
a condition marked by intermittent muscular spasms, caused by malfunction of the parathyroid glands and a consequent deficiency of calcium.

# data[].attributes.body
a bacterial disease marked by rigidity and spasms of the voluntary muscles.

# data[].attributes.body
Tonic seizures involve sudden stiffening and contraction of the muscles. Clonic seizures involve rhythmic twitching or jerking of one or several muscles.

# data[].attributes.body
a sudden involuntary muscular contraction or convulsive movement.

# data[].attributes.body
is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.

# data[].attributes.body
It protects the organs. The cardiac muscle pumps blood. Smooth muscle aids digestion. Smooth muscle ensures blood flow. The muscular system creates movement.

# data[].attributes.body
a cellular protein found especially in microfilaments and active in muscular contraction, cellular movement, and maintenance of cell shape.

# data[].attributes.body
a thin sheath of fibrous tissue enclosing a muscle or other organ.

# data[].attributes.body
a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.
