Muscular System

Any muscle you can control like your arm (you can control most of the muscles in your body). Any muscle you can't control is an involuntary muscle. The only one i can think of is a penis.

The muscles usually work under the the 'all or non law'.Once when your arm is in action all the muscles involved in the shoulder complex works namely,abductors,adductors,rotator cuff,forearm,core etc.And it also depends on which plane you are moving your arms.If it is in the Sagital plane then your working your upper pecs and anterior delts.When you work in the frontal plane, you work lateral delts,lats,supraspinatus etc.The muscles which I mentioned are agonists and stabilizers, and their antagonist counter-parts to play significant role in bringing back your arms down by slowing down the reverse action.And to your surprise your core is the power house to generate the power to lift your arms out.This is prominantly seen with the resisted lifts.But the core gets the energy to provide for the shoulder complex from the legs which work against the ground and utilizes the reaction from the ground efficiently.This is how the kinetic chain works in an individual to incorporate a single simple action.This kinetic chain is fully used by trained persons to do some actions and the wrong way of handling it over years and years end up in strains followed by injuries at different joints....To be simple for your question all the muscles work when you lift your arms!

Temperature affects every single aspect of the human body. Regarding your hands, cold temperatures typically cause your body to shunt blood away from the non-vital parts of your body (as the body itself sees it) which causes your hands to have decreased circulation to all the tissue, including the muscles in your hands, due to what's called vasoconstriction, or constriction of the blood vessels. To put it simply, the decreased circulation causes the muscles to grow "cold" and become stiff. Hypothermia takes this concept into a larger degree. The lower the bodies temperature, the more noticeable the effects of muscles. The muscles themselves require a reaction of calcium ions and chemical reactions at the molecular level, along with a nervous impulse from the brain to work. Since a normal healthy body operates efficiently at 98.6 degrees Fahrenheit, naturally a decrease in the bodies internal temperature would decrease this efficiency slowing the nervous impulse from the brain that is required to initiate the chemical reactions in the muscles themselves to initiate. As the body grows colder in a hypothermic environment, the impulses from the brain slow dramatically causing miscoordination, and muscle weakness. Heat causes vasodilation, or, dilation of the blood vessels resulting in increased blood flow. This is one of the mechanisms the body uses to cool itself off. If the temperature outside the body gets hot enough, the body distributes the blood which is maintained at 98.6 by the hypothalamus of the brain, throughout the body in an attempt to cool the body off. This along with sweating plays a major role in temperature regulation within the body.

The immediate pain can be relieved by stretching out the over-contracted (knotted) muscle. This can be achieved by your, or with the help of someone else, gently but firmly physically extending the limb or extremity that is cramping until the pain is relieved and holding it extended for about a minute so that the cramp does not return.

For prevention of cramps, there are all sorts of folk remedies but you would be best consulting your doctor if you are having a serious cramp problem.

The dorsiflexors include the extensorum longus, the tibialis anterior, and the peroneus.

Feet abducts, everts, and planterflexes due to the Peroneal Tendons. The tendons connects the peroneus brevis muscles and the peroneus longus to bone that when enabled, it will create movement of the feet.

i think you are thinking about the muscular system as a whole which has over 600 muscles

cardiac muscles are located in the heart only

The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.

the smooth muscles as they are located in the hollow organs such as the stomache, unrinary bladder, and respiratory system, they move substances through channels without your control and are not striated

The generic term for connective tissue surrounding muscles, muscle groups, nerves, blood vessels, and otherwise binds structures together is called a "fascia". Fascia are classified by their particular layers, functions and location.

Superficial fascia is located in the subcutis (the lowest layer of the skin, which includes hair, scales, feathers, hooves and nails as appropriate to an invertebrate animal) in most of a body, and blends with the next layer of meshed collagen fibers (the "reticular layer").

Visceral fascia (also known as "parietal fascia") surrounds organs in two layers, and suspends them layers of connective-tissue membranes.

Deep/muscle fascia is the name of the specific membrance that surrounds individual muscles and also divides groups of muscles.

Fasciae contain closely-packed bundles of collagen fibers that grow in a wavy pattern, parallel to the direction of force applied to the muscle when it's expanded or contracted.

The muscles are connected to the bones. Without the bones, the muscles would fall down in a mass of mush, but without the muscles, the bones would not be able to make our bodies move. We would always stay still.

While one muscle contracts, the other muscle in the pair returns to its original length.

The main muscle that bends your upper arm is called the Biceps brachii. The action is called flexion at the elbow. This muscle is on the "front" of the arm.

The muscle that acts against this one is called the Triceps brachii. Its' action is extension at the elbow. This muscle is on the "back" of the arm.

See the link below:

The best prevention is to avoid repetitive overhead arm movements and to develop shoulder strength.

It can but it undergoes incomplete tetanus, in this case there is a short period of relaxtion before a new contractian is initiated. The muscle contraction will go up in a wave like line..

All of them....or do you mean the autonomic nervous system?

A pneumothorax is air in the plural cavity. When a person takes a breath the lung cannot expand. This expatiation normal lowers the pressure in the lungs allowing air to move into the longs, without expatiation during inspiration the pressure does not change and air will not move in.

Three major muscles in the back are the trapezius, latissimus dorsi, and the spinal erectae.

The rotator cuff muscles:

Supraspinatus

Infraspinatus

Teres Minor

Supscapularis

Easily remembered as SITS.

Cerebellum, this area is effected when someone is intoxicated and are not able to walk straight.

The major structures of the muscular system highlight the skeletal muscles. These are the muscles involved with contracting and moving body parts. The smooth muscles are the domain of the subconscious mind, (most organs). The tendons and ligaments connect the bones together as well as the muscles to the bones. And Adipose tissue is a connective tissue that stores fat and cushions joints.

"all muscles are controlled by thought"

Is incorrect, sorry. Voluntary muscles are controlled by thoughts, the ones we don't control by thought, ie, your heart, is involuntary.

So the answer is voluntary. :)
