What does a skeletal muscle do?

Moves your skeleton apparently. It's job is to move your skeleton. The bones help structure this body so it can sustain movement.

Muscle cells undergo hypertrophy when they are exercised (resistance training).  Hypertrophy means each fibre that makes up the muscle increases in width but not in number.  The current theory is that small tears are produced in the muscle when it is worked out.  As these tears are healed during recovery (~48hrs after exercise) the muscle lays down new contractile filaments (protein) and begins to increase in diameter.  Some research does suggest that hyperplasia (increased muscle cells) can occur when the muscle reaches a very large size, but this has not been completely proven yet.  Satellite cells, which are stem-like cells in the muscle can also be stimulated by hormones produced by exercise (like IGF-2) to migrate into the muslce and join with existing muscle cells.  This adds nuclei to the existing cells along with contractile filaments allowing the muscle to increase in diameter (hypertrophy).

The skeletal system consists of about 206 bones, 26 of which are in each hand and foot, in order for the skeletal system to function and move it requires muscles to contract. Muscles can't push only pull. The muscles that contract and cause the arm or leg to lift are called flexors, the ones that cause it to extend are called extensors. there are five different types of joints, pivot, ball and socket, hinge, gliding, saddle. and a sixth one is called condyloid. the ball and socket joints are found on the shoulder and the hip and provide the body with all types of movement. the saddle joints are only on the base of the thumb. the hinge joint is found in the hip and the elbow. the gliding is found in the ankle. the pivot in only at the top of the neck. the condyloid is found at the base of the palm. fixed joints are ones that are immovable. such as on the cranium. your axial skeleton consists of your cranium,ribs and spine. the appendicular is everything else.\n\nThe skeletal system is the only thing keeping us from being a mass of flesh and muscle. It provides protection and support for our bodies. The bones also contain bone marrow which produces red blood cells. there are two types of bone. the soft inner layer called the spongy bone and the hard compact bone on the outside. hervasian canals in the bones are the ducts for blood vessels and ateries. Osteocytes are trapped bone cells inside the bones. along with the bones there are softer parts of your body that are made of cartilage. Such as your ears and parts of your ribs. the names of the bones are the cranium, spine, coccyx, ribs, humerous, radius and ulna, tibia and fibula, phalanges, tarsals, metatarsals, carpals, and metacarpals, phemur, pelvis, pubis, and the mandible and maxila. the phalanges are in the fingers and toes. the carpals are in the hand along with metacarpals and the tarsals and metatarsals are in the foot. the tibia and fibula are the shin and the radius and ulna make up the forearm. all of these make up the skeletal system and muscular.

All of the above are well understood, it's just that skeletal and cardiac mucsle are more complicated, therefore there is more information on them.  Smooth muscle contraction can function solely on its intrinsic plexus, its built-in nervous system that only receives fine tuning from the para and sympathetic nervous systems.  It even has its own immune system, Peyer's Patches for example.

Muscles are the means by which you can move bones and are usually connected across 2 bones. The parts of your body with a high number of bones are also going to have a high number of individual muscles. Depending on the way you seperate body parts, I'd go with hands or feet as having the most number of muscles.

The sets of muscles that have the finest control have the fewest muscle fibers per motor unit.  This makes sense because when a neuron depolarizes all of the muscle fibers it is connected to depolarize and contract.  This is refered to as a "All-or-None" response.  Muscle fibers don't contract half way.  So if you want precise control over your muscles you have to have a lot of neurons innervating it.

Creatine is natural in skeletal muscle and is not harmful. The "good and bad" creatines have alot to do with how much is absorb by your body as useful creatine. Check out Muscular Development, they have a website.

Yes, it does. Core muscles, leg muscles, and even arm muscles get varying degrees of a work out when you run.

The contraction of a skeletal muscle is caused by the movement of actin and myosin fibers resulting from influx of exracelluar calcium caused by surface depolarization of the cell initiated by presynaptic discharge of a motor neuron. If this is a homework question, I suppose a one word answer would depend on the nature of the course discussion to which this question is addressed.

According to the text: "Principles of Anatomy and Physiology" by Tortora and Grabowski, 7th edition,1993, there are "nearly 700 skeletal muscles in the human body." These are the named voluntary muscles and range in size from a few millimeters in length (the stapedius in a middle ear) to the massive thigh quadriceps (perhaps 45-50 cm in length in large adult males).

Skeletal Muscles, the muscles that moves your limbs, eyelids, lift your face, external sphincters of your anus and urinary bladder...\n\nHeart Muscles (Cardiac Ms) - these are also made of striated tissues

Agree with Mr. Brightside, the person before me.\n\nMuscle tissue is a group of muscle cells.\nMuscle tissue is what generally called as "meat" or "flesh".\nMuscle tissue is the most abundant tissue in the body.\nIt is composed of cells called muscle fibers.\n\n3 types of muscle tissue:\n\n1. Smooth muscle\nIt can be found in intestines, blood vessels, urinary and reproductive tracts.\n\n2. Skeletal muscle\nIt can be found in arms and legs.\n\n3. Cardiac muscle\nIt can be found in the walls of heart.\n\nSMOOTH MUSCLE\nContraction and relaxation of smooth muscles are responsible for involuntary body activities such as peristaltic movement along the digestive tract.\nSmooth muscles contract more slowly than skeletal muscles but remain contracted for a longer period of time.\n\nSKELETAL MUSCLE\nSkeletal muscles are involved in volutary movements. They contract and relax to move the bones.\n\nCARDIAC MUSCLE\nCardiac muscle contract to pump blood to all parts of the body. The contraction of cardiac muscles is involuntary.

When muscles contract they use energy that is derived from food. It is a two-step process. The first step occurs in mitochondria, where the energy from molecules like glucose or fats is locked away in ATP (adenosine triphosphate). This ATP travels from the mitochondria to sites in the muscle where energy is needed, and the energy is released and used. At both of these stages there is the possibility for energy to be lost mainly as heat, causing a big reduction in efficiency. The proportion of food energy that ends up making the muscles move varies considerably between people from 15 to 30%.

I'll try to answer this question without writing a thesis or dissertation.  Skeletal muscles have an origin, insertion, and tend to cross an axis point.  For example, the two muscle that make up the bicep originates from a point underneath the front deltoid.  They insert below the elbow and move the lower part of the arm inward to your body.  This is done through the brain sending a signal to the muscle to move.  These signals are neurons, which travel along the nerve pathways.  So the brain thinks bring the hand to the shoulder and the bicep moves your lower arm inward.  This is pretty much consistent with the other skeletal muscles in the body.  The brain sends signals that tell the muscle to contract or extend.  Well that is about as simple as I can put it.  I'm sure someone else can probably elaborate and give a better explanation.

The heart is a powerful muscle slightly larger than your clenched fist. It works as a pump to send oxygen-rich blood through all parts of your body. Blood contains oxygen and nutrients that every cell in your body needs to survive. The oxygen-rich blood travels throughout the arteries and vessels, nourishing the body so that it can function properly.\n\nYour heart will beat an average of 100,000 times per day. In that time, it pumps more than 4,300 gallons of blood throughout your entire body.

Inscrease your muscle mass.  Muscle cells use more energy than fat cells, so you'll burn more calories every day.
