Muscular System
The muscular system allows humans to move. Muscles also provide strength, balance and heat.

What are three facts about muscles?
There are 600 muscles in your body which do everything from pumping blood throughout your body to helping you lift your heavy backpack.
Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands or even tens of thousands, of small fibres make up each muscle.
You have three different types of muscles in your body: smooth muscle, cardiac muscle, and skeletal muscle.
You control some of your muscles, while others --- like your heart --- do their jobs without you thinking about them at all.
Smooth muscles --- sometimes also called involuntary muscles --- are usually in sheets, or layers, with one layer of muscle behind the other. You can't control this type of muscle. Your brain and body tell these muscles what to do without you even thinking about it. You can't use your smooth muscles to make a muscle in your arm or jump into the air.
Smooth muscles are at work all over your body.
In your stomach and digestive system, smooth muscles tighten up and relax to allow food to make its journey through the body.
Your smooth muscles help if you're sick and you need to throw up the muscles push the food back out of the stomach so it comes up through the esophagus and out of the mouth.
Smooth muscles are also found in your bladder.
When they're relaxed, they allow you to hold in urine until you can get to the bathroom. Then they contract so that you can push the urine out. These muscles are also in a woman's uterus, which is where a baby develops. There they help to push the baby out of the mother's body when it's time to be born.
Smooth muscles work behind your eyes; these muscles keep the eyes focused.Just like smooth muscle, cardiac muscle works all by itself with no help from you.
The muscle that makes up the heart is called cardiac muscle. It is also known as the myocardium The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body.
Skeletal muscles are voluntary muscles, which mean you can control what they do. Your leg won't bend to kick the soccer ball unless you want it to.
These muscles help to make up the musculoskeletalsystem --- the combination of your muscles and your skeleton, or bones.
Tendons are cords made of tough tissue, and they work as special connector pieces between bone and muscle.
The tendons are attached so well that when you contract one of your muscles, the tendon and bone move along with it.
Some of your biggest and most powerful muscles are in your back, near your spine. These muscles help keep you upright and standing tall.
The tendons are tough bands of connective tissue that attach muscles to bones.
The quadriceps are the part of muscle that straightens the knee.
Muscle is the contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells.
Muscle cells contain contractile filaments that move past each other and change the size of the cell.
The function of muscles is to produce force and cause motion.
Muscles can cause either locomotion of the organism itself or movement of internal organs.
Cardiac and smooth muscle contraction occurs without conscious thought and is necessary for survival.
Voluntary contraction of the skeletal muscles is used to move the body and can be finely controlled.
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
Various exercises require a predominance of certain muscle fiber utilization over another.
Your quadriceps, or quads, are the muscles on the front of your thighs. Many people who run, bike, or play sports develop large, strong quads
Your heart is as big as your fist.
NO. its full of chemicals like acesulfame potassium and its primarily a soy protein base. use a natural whey based shake or onesource optimal nutrition shake and stay away from anything in a plastic bottle because its full of chemical preservatives and cheap ingredients.
Haha yeah it works as for what its used for. As for above Muscle milk is actually a milk protein base with calcium casseinate as well as milk protein isolate so get your facts straight before you answer questions. It is a healthy combination of proteins, fats, and carbohydrates that should be used post workouts because proteins are absorbed better when they are combined with carbohydrates.
What is the strongest in your body?
The proper term is "Calcaneal Tendon" (the anatomical name). The common name is "Achiles Tendon", which is the strongest tendon in the body.

Compare and contrast between skeletal muscles and smooth muscles?
Skeletal muscles look like long muscle fibers with a nuclei in each one, looks striated or striped. Compared to a smooth muscle that looks like sheets of thin cells each have a nucleus as well but looks smooth.
How long does it take for a strained rotator cuff to heal?
A rotator cuff surgery can have you out for about 6 weeks before you are functional again. Just do as the doctor says after surgery, take you pain medicines and therapy if needed and you will be fine.

What connects to your muscles?
Muscles are attached by tendons (with a few exceptions). The muscles are attached to the tendons by a musculo-tendonious junction. The tendons are a part of the muscle that tapers off to a strong tendon. These tendons are what makes the fingers move and are so important in all movement of the body, ie, foot, mouth, elbow, hand and wrist.,,what makes these tendons work are impulses from the brain that sends a message to the muscle that the tendon is attached. This is called a motor function........makes sense doesn't it.
What are bundles of muscles fibers within a muscle called?
In forming whole muscles, individual muscle fibers are arranged in bundles, or fascicles, held together by fibrous connective tissue.
Answer is Fascicles.
How does the skeletal muscle function affect the maintenance of body temperature?
Muscle activity produces heat so that exercise creates a heat surplus that can actually be fatal. In response to exercise the body has to redirect blood flow to the skin to facilitate heat transfer out of the body.
What is the function of the sartorius muscle?
The sartorius muscle - the longest muscle in the human body - is a long thin muscle that runs down the length of the thigh in the anterior compartment. Its upper portion forms the lateral border of the femoral triangle.
Can you name two parts in a human body that the involuntary muscles control?
The heart and bowel are two parts that are are under involuntary muscle control. The uterus and the gallbladder would be others. All organs having smooth muscle are controlled involuntarily. All blood vessels, bronchi, and Oddi's sphincter are additional examples. The voluntary control of muscles concerns striated muscle, grossly meaning all of those things you can consciously move such as arms, legs, torso and abdomen neck and face.
What muscle flexes the shoulder joint?
1) pectoralis major 2) anterior fibers of deltoid 3) biceps brachii 4) corachobrachialis 1) pectoralis major 2) anterior fibers of deltoid 3) biceps brachii 4) corachobrachialis 1) pectoralis major 2) anterior fibers of deltoid 3) biceps brachii 4) corachobrachialis
Its the Triseps Branchii. Retard. That's the answer!
no need to be a dick. and you're calling him a retard, while you can't spell triceps or brachii right.

What is a cardiac blood pool scan?
A normally functioning left ventricle will contract symmetrically, show even distribution of the radioactively tagged protein, and eject about 55-65% of volume of blood it holds on each contraction.
The characteristic reddish brown color of skeletal muscle comes from which substance?
myoglobin gives the muscles the reddish brown color
Which organs muscles move food back into the pharynx?
The tongue pushes food to the back of the mouth.
Are there over 600 muscles in our body?
Yes, there are way more than 300 muscles in the human body. The minimum number of muscles in the human body is 639 muscles with a maximum pushing 850.
