Muscular System

Rectus abdominis.

The heart is a muscle because it is it is an involuntary muscle because it keep working and never stop also it is not under our control :)

True

All muscles can move, but only skeletal muscles are voluntary. The cardiac and the smooth muscles cannot be moved by your will, but skeletal muscles can be.

MRI (magnetic resonance imaging). This imaging technique applies very high magnetic field in pulses to tissues. The magnetic field is measured in tesla. The present MRI scanners used are 1.5 to 3 teslas.The tissues align and revert back when the field is removed and the energy is released which is captured in and processed by computer in image format. This investigation does not have radiation hazard and is the investigation of choice to study soft tissues especially spinal cord and brain.

There are a number of muscles that produce inversion of the ankle.

Tibialis Anterior

Extensor Hallucis Longus

Tibialis Posterior

Flexor Hallucis Longus

Flexor Digitorum Longus

tibialis anterior

Muscles make possible every move we make, even when we are sleeping. Your muscles move according to what they are fromed. To be more specific, a muscle is made up of many bundles of muscle fibers. Each of these bundles of fibers is called a motor unit. Each unit has a motor nerve which branches out at its tip. Each muscle fiber, therefore, has its own nerve ending to stimulate it. An electrochemical impulse is transmitted by chemicals from the nerve ending to the fiber, causing the fiber in that motor unit to contract and this is how each muscle of your body moves.

dial 911. you coul be having a heart attack!

The zygomaticus is a skeletal muscle, and as such is a 'striated' muscle. It is also a parallel muscle. It functions in chewing, and is therefor one of the 'Masticating' muscles.

Muscles always contract entirely i.e. every part of the muscle which contains myosin and actin (contractile proteins) is able to contract and does contract almost simultaneously.

While they often can be used to indicate the same thing, strictly speaking, "atrophy" means a loss of function due to disuse. "Dystrophy" is more general, meaning "other than normal". The distinction usually comes down to this: something that was originally normal will waste away via atrophy, while something that was never normal to begin with may suffer dystrophy.

That would be your heart. That is my favorite treat.

Both types of muscle come in a variety of sizes. In general the larger muscles are the striated muscles. The power of a muscle is generally proportional to its cross sectional area (bigger is usually more powerful).

Squats are one of the best, if not the best, exercises you can do. This is because they work so many muscles, while forcing you to stabilize and balance your body under a heavy load. The primary muscles involved are the quadriceps, hamstrings, glutes, and adductors.

Every time you pull a muscle, it stretches it so it will hurt. Putting ice on it will help the muscles go back into its former position. You should put ice on your injured leg evey time you pull it, but it really depends on how much you have pulled it to determine whether or not to put ice on it.

Uh all of your muscles DO work together, when you move or lift things......idiot

The temporalis

The biceps femoris runs down the outside of the leg and inserts on the head of the fibula, the semitendinosus runs down the inside of the leg and inserts on the front of the tibia and the semimembranosus runs down the inside of the leg underneath the semitendinosus and inserts on the front of the tibia as well.

Muscular strength is the maximum amount of force that a muscle can exert.

The a voluntary muscle contracts involuntarily, you will see a little movement through your skin. These movements are often called Tics, Twitches, and Spasms.

If the involuntary contractions are widespread and very energetic, they may be called, "Seizures".

Muscles generally come in three flavours; Skeletal or voluntary musculature, cardiac or heart muscle and smooth muscle tissue.

You're probably looking for smooth muscle tissue- it moves food through your intestines (peristalsis) and places like that. The bodies organs generally have no need to be surrounded by muscle ( and they aren't ), in fact muscles around them might seriously impair their normal functions.

The vagal nerve stimulator has two parts: an electrode that wraps around the left vagus nerve in the neck; and a pulse generator, which is implanted under the skin below the collarbone. The two parts are connected by a wire.

Calcium ions bind to troponin, changing troponin's shape

The heel raise exercise works your calf muscles, which are two separate muscles. The first is the gastrocnemius muscle, which is the outermost calf muscle on the back of your lower leg. Your soleus muscle is the second part of your calf muscle and rests underneath the gastrocnemius. However, the soleus is slightly wider than the gastrocnemius.
