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

Electrophysiological Basis for Normal Automaticity (Impulse Formation) Automaticity is defined as the ability of heart cells to spontaneously depolarize and generate an action potential.

muscle excitability In a muscle fiber, the inducibility to contract. This is a function of the chemical and electrical state of the sarcolemma and the time since a previous stimulus was applied.

# data[].attributes.body
the quality of muscle that enables it to yield to passive physical stretch.

# data[].attributes.body
Extensibility is the ability of a muscle to be stretched or extended. Muscle cells are specialized for contraction. Muscles allow for motions such as walking, and they also facilitate bodily processes such as respiration and digestion.

The condition of being able to contract or shrink (used especially of muscles) contractility(Noun) The extent to which something contracts or shrinks. contractility(Noun) A term used in physiology to describe the performance of cardiac muscle.

Calcium assists in muscular contractions and regulating the rate of contraction of your cardiac muscle. Your muscles contract through a process known as the sliding filament theory. In this process, myofilaments inside your muscle fibers grab hold of one another and slide to produce a muscular contraction.

# 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
a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cell.

# data[].attributes.body
The sliding filament theory is a suggested mechanism of contraction of striated muscles, actin and myosin filaments to be precise, which overlap each other resulting in the shortening of the muscle fibre length. Actin (thin) filaments combined with myosin (thick filaments) conduct cellular movements.

a muscle which is connected to the skeleton to form part of the mechanical system which moves the limbs and other parts of the body.

# data[].attributes.body
Cardiac muscle tissue is able to set its own contraction rhythm due to the presence of pacemaker cells that stimulate the other cardiac muscle cells.

# 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
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.

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

# data[].attributes.body
A decrease in maximal force or power production in response to contractile activity.

5 Basic Functions of the Muscular System

# data[].attributes.body
The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation

# data[].attributes.body
Made up of sheets of connective tissue that is found below the skin. These tissues attach, stabilize, impart strength, maintain vessel patency, separate muscles, and enclose different organs.
