1)stiffening of the joints and muscles of a body a few hours after death,

2)the third stage of death,

3)caused by chemical changes in the muscles post mortem,

# data[].attributes.body
1)occurring in cells that do not normally possess that property

2)automaticity occurring in cells

3)cells with this capability are called automatic cells

# data[].attributes.body
1)its cells must be stimulated

2)the muscle cell is then "excited" from an electrochemical standpoint.

3)This results in an influx of positively charged sodium ions into the muscle cell

# data[].attributes.body
1)it can be stretched or contracted by some amount above or below

2)Your muscles require the property of elastic recoil for them to be able to do their jobs.

3)recoil to their resting length after being stretched during a series of curling exercises

# data[].attributes.body
1)the capacity to lengthen.

2)Your muscle cells can be stretched to about three times their contracted length without rupturing.

3)Muscle cells contract, and in order for them to retain this ability

# data[].attributes.body
1) it is also the foundation for smooth muscle contraction

2)Contractility is the ability of muscle cells to forcefully shorter

3)Contractility refers to the ability for self-contraction,

# data[].attributes.body
1)When the brain signals the muscle to contract, the body pulls calcium from the blood into the muscle cells.

2)The calcium binds with the troponin and draws it out of position

3)calcium is released into the fiber

# data[].attributes.body
1)fibrous protein that forms (together with actin) the contractile filaments of muscle cells

2)involved in motion in other types of cells.

3)They are ATP-dependent

# data[].attributes.body
1)protein that forms (together with myosin)

2)also involved in motion in other types of cells.

3)forming filaments that make up a main component of the cell's supporting matrix or cytoskeleton

# data[].attributes.body
1)filaments of muscle fibers slide past the actin (thin) filaments during muscle contraction,

2)fibres bind to create cross-bridges and slide past one another, creating a contraction.

3)The breakdown of ATP releases energy which enables the Myosin to pull the Actin filaments inwards and so shortening the muscle

# data[].attributes.body
1)is one of three types of vertebrate muscles

2)voluntary

3) separated and flat with many little  nucleus inside

# data[].attributes.body
1)anchored by tendons

2) voluntary muscle

3)tubular and located all around the body

# data[].attributes.body
1)muscle tissue in which the contractile fibrils are not highly ordered, very smooth and flat

2) occurring in the gut and other internal organs

3)involuntary

# data[].attributes.body
1)medical sign consisting of the involuntary contraction of muscles,

2)caused by disease or other conditions that increase the action potential frequency of muscle cells

3)Tetany can also be caused by magnesium deficiency or too little potassium.

# data[].attributes.body
1)serious bacterial infection that causes painful muscle spasms and can lead to death.

2)tetanus appear anytime from a few days to several weeks after tetanus bacteria enter your body through a wound

3)Spasms and stiffness in your jaw muscles (trismus)

# data[].attributes.body
clonic
1)A type of seizure that involves a loss of consciousness and violent muscle contractions.

2)Clonic means sustained rhythmical jerking
tonic
1)continuous tension or contraction of muscles

2)producing or adapted to produce healthy muscular condition and reaction of organs

# data[].attributes.body
1)Involuntary contractions of a muscle, typically harmless and temporary, but can be painful.

2)Muscle spasms can have causes that aren't due to underlying disease

3)include extreme fatigue from overexertion, not using the muscle enough, low magnesium, or low potassium.

# data[].attributes.body
1)decline in ability of a muscle to generate force

2)decreases your muscles' ability to perform over time.

3)It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages

# data[].attributes.body
1)Muscles hold the body

2)Make movement possible

3)Move food through the digestive system

4)Muscle movement aids the flow of blood through veins

5)Muscle actions moves fluid through the ducts and tubes associated with other body systems

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

beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs.

interwoven system of fibrous connective tissue found throughout the body.

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

2)the hamstring of a quadruped.

3)connects muscle to bone and is capable of withstanding tension.
