Rigor mortis is a postmortem change resulting in the stiffening of the body muscles due to chemical changes in their myofibrils. Rigor mortis helps in estimating the time since death as well to ascertain if the body had been moved after death.

Automacity is the ability to spontaneously depolarize and generate an action potential. It is usually the result of learning, repetition, and practice.

Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.

Tissue elasticity is the ability to stretch a muscle to reach its full range of movement without restriction. Tissues often become restrictive and inelastic resulting in an increase in muscle tightness and pain.

Extensibility is the ability of a muscle to be stretched. Tissue extensibility relates to tissue flexibility, which is related to the strength and power that your muscles are able to generate.

Contractility is the ability of muscle cells to forcefully shorten. Contractility allows muscle tissue to pull on its attachment points and shorten with force.

Calcium facilitates the interaction between actin and myosin in muscle contractions. Calcium's positive molecule is important to the transmission of nerve impulses to the muscle fiber.

It is known as a group of motor proteins which help with movement hence its name. They are also known for muscle contraction.

# data[].attributes.body
A protein that forms in the contractile filaments of the cell. This protein ultimately helps with the movement of muscles.

# data[].attributes.body
This is the theory that allows muscles to contract in the body. Myosin binds with actin that causes the actin filament to slide across the myosin filament.

These muscles are mostly found close to tendons which connect muscles to bone. This is the muscle that often characterizes locomotion in the body.

It is the muscle that is only found in the heart. It is involuntary and is responsible for the ability to pump blood into the body.

# data[].attributes.body
It is the muscle that is found in most internal organs such as the digestive system. It is involuntary and it contracts slowly and automatically.

# data[].attributes.body
It is a condition characterized by the cramping of muscles. It is often caused by low calcium level.

Tetanus is a painful muscle contraction that can lock up certain parts of your body. It is often caused by stepping on a rusty nail.

Tonic seizures often cause the stiffening of the muscles. Clonic seizures often cause jerking or twitching in the body.

# data[].attributes.body
It is the painful contraction and tightening of the muscles. It is all involuntary and very unpredictable.

# data[].attributes.body
It is a symptom that decreases a muscle's ability to perform certain tasks. The muscle will be very weak and it is often goes away in about 10 minutes.

5 basic functions of the muscular system

# data[].attributes.body
The 5 functions include the movement of the body, movement of food, movement o blood, production of heat, and the protection of internal organs.

It is a thin case of connective tissue that is on the outer covering of all organs. It provides shape for muscle, tissues, and organs.

A Tendon is what connects a muscle to a bone. It helps muscle move bones to allow walking and movement in your body.
