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.

muscle that make up your heart.The thick muscle of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body.

Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs. It is considered smooth because it does not have the microscopic lines.

Overly stimulated nerves cause involuntary muscle cramps and contractions, most often in the hands and feet.

Tetanus is a serious bacterial disease.tetanus affects your nervous system, leading to painful muscle contractions, particularly of your jaw and neck muscles.

Otherwise known as muscle cramps, spasms occur when a muscle involuntary and forcibly contracts and cannot relax.he most common sites for muscle spasms are the thighs, calves, foot arches, hands, arms, abdomen and sometimes along the rib cage.

Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time.Exercise and other physical activity are a common cause of muscle fatigue.

5 basic functions of the muscular system

1. The muscular system creates movement.                                2.protects organs              3.cardiac helps pumps blood      4. produce heat/regulate body temperature                                        5. to breathe

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

a thin sheath of fibrous tissue enclosing a muscle or other organ.it provides a framework that helps support and protect individual muscle groups, organs, and the entire body unit.it is found surrounding individual muscle

automaticity. a property of specialized excitable tissue that allows self-activation through spontaneous development of an action potential, as in the pacemaker cells of the heart.

the ability of the cardiac muscle to respond to a stimulus of adequate strength & duration by generating and AP

Muscle-tendon elasticity complex is the natural ability of your musculoskeletal system to 'return to its original state'.

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.

When the brain signals the muscle to contract, the body pulls calcium from the blood into the muscle cells.

# data[].attributes.body
a molecule that uses chemical energy to perform a deliberate motion. Myosin captures a molecule of ATP, the molecule used to transfer energy in cells, and breaks it, using the energy to perform a "power stroke."

# data[].attributes.body
is the ability of muscle cells to forcefully shorten. For instance, in order to flex your elbow you need to contract  the biceps brachii and other elbow flexor muscles in the anterior arm. Notice that in order to extend your elbow, the posterior arm extensor muscles need to contract.

a protein that forms the contractile filaments of muscle cells, and is also involved in motion in other types of cells.

A fibrous connective tissue which attaches muscle to bone.   A tendon serves to move the bone or structure.Also connects other structure like an eye ball to a muscle.

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.
