Rigor mortis is the third stage of death. Rigor means "Stiffness" while mortis means "Of death". This is one of the recognizable stages of death, caused by chemical changes in the muscles.

Contractility of a muscle is the ability of a muscle to shorten with force. An example of this would be pulling a weight towards your chest. this is contracting your arm muscles

Automaticity is the ability to do things without occupying the mind, or without much thought. This means that the automaticity of muscles would be the ability of your muscles to work without having to think too hard about this. an example of this would be muscle memory.

The excitablity of a muscle is the capacity of a muscle to react to a stimulus. they respond to stimulus by producing electrical signals. Muscle excitability makes it possible for the nervous system and some times the endocrine system to regulate muscle activity.

Elasticity of muscles is the ability of a muscle to recoil to normal resting length after stretch. One way to think of this is like a rubber and. you stretch it, and once you let it go it returns back to its normal size. That's the same idea of the elasticity of muscles.

# data[].attributes.body
A muscle can be stretched to its normal degree and farther to a certain point being able to do this comfortably is flexibility. One way to improve your elasticity or flexibility of your muscles is to stretch,

Calcium is a mineral found inside the body. calcium is important because our muscles rely on calcium to be able to contract. long term calcium deficiencies can cause bone loss, and weakness in muscles.

Moysin is a type of dependent motor protein. Moysin is best known for its role in muscle contraction. They are also known for their involvement in a wide range of mobility processes in eukaryotes..

Actin is a family of globular multi-functional proteins that form micro filaments. It is found in essentially all eukaryotic cells.Actin participates in many important cellular processes, including muscle contraction.

# data[].attributes.body
The sliding filament theory explains the mechanism of muscle contraction. This is based on muscle proteins that slide past each other to generate movement. According to the theory the myosin filaments of muscle fibers slide past the actin filaments during ,muscle contraction.

tetany is a type of seizure, it consist of involuntary contractions of muscles. This may be caused by disease or other conditions. Muscle cramps which are caused by the disease tetanus are not classified as tetany, because they are due to a lack of inhibition to the neurons that supply muscles.

Tetanus, also known as lockjaw, is an infection with muscle spasms. In the most common type, the spasms begin in the jaw and then progress to the rest of the body.These spasms usually last a few minutes each time and occur frequently for three to four weeks.

In a tonic seizure, the body, arms, or ;legs may be suddenly stiff or tense. Tonic seizures usually begin in both sides of the brain. These seizures can occur in anyone, but are often seen in people with epilepsy syndrome.

Clonic means susatined rhythmical jerking. During a clonic seizure, the jerking of the body or parts of the body are the main symptom. Clonic seizures can affect people of all ages including newborns.

Muscle fatigue 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. There are two main causes of muscle fatigue: neural fatigue and metabolic fatigue.

A spasm is a type of voluntary muscle movement. It is a sudden, violent, involuntary contraction of one ore more muscles. This is most common in the skeletal muscles because they are responsible for motion

Cardiac muscles form the muscular walls of the heart. Cardiac muscles have the same dark and light bands as the skeletal muscles. Cardiac muscles are involuntary because they are in constant contraction and relaxation

# data[].attributes.body
Skeletal muscles are attached to the bones of the skeleton, and make motion possible. Skeletal muscle is known as voluntary muscles, because we control then according to our will. under a microscope skeletal muscle has dark and light bands.

Smooth muscles are located in the walls of the internal organs. They are also known as involuntary muscles because they are controlled automatically by your nervous system. Smooth muscle does don't have the dark and light bands that make the stripped appearance which is seen in skeletal muscle. In conclusion smooth muscle has a very smooth appearance

-holds the body erect, and makes movement possible
-generates nerly 85% of heat to keep the body warm
-moves food through the digestive system
-allows movements like walking and helps to aid the flow of blood through the veins as it returns to the heart
-helps move fluid through the body systems

Fascia is the sheet of fibrous connective tissue that covers, supports, and separates muscles. Fascia is flexible to allow muscle movements. It does not have elastic properties to accommodate the swelling of the enclosed tissue

the tendon is a narrow band of nonelastic, dense, fibrous connective tissue. The tendon attaches muscle to bone, tendons are often confused with ligaments. For example the Achilles Tendon attaches the muscles of the calf to the heel bone.
