Muscular System

Electronic signals are sent through the nuerons of the brain to the sight of desired movment. When they reach this spot the signals close an electric pathway and tell to muscle to expand or contract.

Skeletal muscle

It's the muscle that surrounds the testicles and spermatic cord. It twitches involuntarily when the cremasteric reflex is stimulated, or to raise the testicles closer to the body when it's cold or the man is sexually excited. It can also be twitched voluntarily in most men using Kegels, where the muscles that tighten the anus, and stop the flow of urine, are contracted. Some men can also contract it by contracting their abdominal muscles.

torn muscle tissue

== That is actually what that muscle group is called, to the best of my knowledge. == The four muscles that make up the quadriceps group are: * Vastus Medialis (Internus) * Vastus Intermedius * Vastus Lateralis (Externus) * Rectus Femoris

if yall are wondering if ur uterus is involuntary or voluntary the answer is involuntary.

It is easiest to think of the lymphatic system as being, in many ways, analogous to the circulatory system. Both are extensive networks of tubes that go virtually everywhere in the body. But where the circulatory system moves blood around the body, the lymphatic system moves a clear liquid known as lymphthroughout the body.

Different muscles move different parts of the body.

muscles are made up of cells

In visceral organs: for example, the stomach, urinary bladder, small intestines. Smooth muscle cells are also found in arteries and arterioles

If done properly the rowing machine is primarily increases leg strength. Along with this however your lats, abs and arms may see a significant increase as well. That having been said weights will be more effective at increasing muscle mass though rowing will get you fitter as well.

Thermoreceptors

It usually takes between four and six months to fully recover from rotator cuff surgery. The first couple weeks after the surgery, the arm has to remain immobilized; after this, physical therapy begins and becomes more intense over the weeks to follow. A person's overall health, whether they smoke, and if their blood sugar is controlled (if they have diabetes) can all make a large difference on how well he or she will heal from the surgery and how quickly he or she will be able to have full use of their arm again.

Usually after the first week it starts getting better, but it depends on you following doctor's advice. I had this procedure 2 years ago, for the first week it was VERY VERY rough but the next week it was better by the third week, it was back to business as usual. the first week is important, no activity at all.

I had rotator cuff surgery and was in a sling and immobilized for 1 week. Then, went to physical therapy and was told to do a few exercises letting my arm drop down to my side and just let it move in small circles...moving it with the momentum of your body. The Dr. also told me to leave it out of my sling at home..but never to try to raise it above my shoulder height, or to try and reach my hand where I could not see it. When going out in public, to wear my sling. Every week I attend physical therapy. I am at week 4 and being able to do most normal movements..except any lifting. I had arthroscopic surgery, and I am told it is very different from the way it used to be done, which I am sure it makes a difference with your recovery.

The tibialis anterior is the name of the muscle located on the front surface of the lower leg

Disuse atrophy is degeneration and loss of muscle mass. The size, shape, tone, and strength of muscles (including the heart) are maintained with mild exercise and increased with strenuous exercise. Promoting exercise to maintain a patient's muscle tone, joint mobility, and cardiovascular function is an important nursing function.

Once you deplete the available energy reserves of a muscle it starts feeding on itself, burning protein instead of sugar. When you do that, the muscle starts to produce lactic acid as a product of converting protein to energy. The lactic acid is toxic and painful. The muscle will hurt until it is able to purge the lactic acid. Part of the process causes the muscle to enlarge and store more energy for NEXT time, resulting in larger and stronger muscles which can work for a longer time.

straited muscle are another form of skeletal muscle.

The tendon between the muscle and the bone connects the muscle to the bone.

when you breathe in the intercostal muscles and the diaphragm contract lifting the ribs up.

WRONG>>>(Tina Lockwood had the biggest biceps for a woman, but now it's probably Cornelia Brandt.)

no the largest biceps ever recorded on a woman is renee Toney 20" on her right arm and 20"1/4 on her left

There are more than four major functions of the human bodies muscles. You may be able to group them together based on what specifically is being asked of you.

Major Muscle Functions:

1.) Producing Movement

2.) Maintain Body Posture and Body Position

3.) Stabilize Joints

4.) Generate Heat

5.) Make up a layer of organs and blood vessels to dilate and constrict

6.) Contract the heart and cause blood to be pumped throughout the body.

There are unknown amounts of fibers (fibre) in muscles

Tendons are shiny white tissues at the ends of the muscles that attach muscles to bones.

Dorsiflexion of the foot uses four muscles. These are the tibialis anterior, extensor digitorum longus, extensor hallucis longus, and the peroneus tertius. The prime mover is the tibialis anterior.
