What is responsible for muscle growth? Like after exercise what triggers the cells to produce more muscle cells. What chemicals?

That’s not settled. Right now, the leading hypothesis is that exercise damages the cells, which grow while repairing. I don’t know how much experimental support the idea has.
When you get into the fringes of sports and nutritional science, there’s a lot of "information," but not a lot of reliable research.

Skeletal muscle cell do not typically reproduce i.e. divide. The number of muscle cells do not increase however they do increase in size. There are some that indicate that they may even split but not as in mitosis. Damaged cells do repair and "over repair" thus causing an increase in muscle size. Muscle size is also inhanced by increased contracture. Hypoxic conditions in the muscle cells increase lactic acid which also stimulates the increased production of human growth hormone (HGH). The Japanese have introduced a new type of quick workout which involves the use of constriction bands on muscles to restrict blood flow and shorten the time needed to reach an anaerobic muscle environment and increase lactic acid production. Fewer reps and fewer sets are needed to tire (damage) the muscle. Have not tried it and probably won’t.
To repair damaged muscle tissue takes time, amino acids and energy. You must eat right and this is why one should not work the same muscle hard every day. A day of rest allows for repair and prevents over training.
Big muscles are found in the weight room, hideing under the big weights. You have to pick up a lot of the big weights to find them.
Shut up and lift.

Yeah I don’t think I will go into depth like the post before, but I can help you. Basically when you workout you put a strain on your muscles. This indeed causes muscle damage. As a result you body breaks down the proteins that you eat into what are called amino acids. These are the basic building blocks of your muscle.
Using these fundamental building blocks, your body begins to repair the muscle fibers that were damaged, making them bigger and stronger than they were before.

Some experts said you need more proteins for muscle growth. But some said that unecessary. I think the second are right, but when you do some research there are nothing about less protein and good nitrogen balance.
THANK YOU FOR THE ANSWER …

Hmmm… Proteins are essential for everything, such as growth and repair. With more muscles indeed comes more mass, and more proteins are needed. You do not need more proteins for muscle growth, but to maintain health, proteins must be consumed in larger amounts, that is considering you are already healthy. If proteins are severely lacking and you are suffering from severe malnutrition, protein consumption is required to grow muscles. This is because your muscles are most likely being consumed instead of proteins, because you are lacking basic amino acids for cellular processes. Therefore, of course you need proteins for anything, but if you need more proteins to grow muscles, it is unnecessary, providing you are healthy.

People grow to their normal size because of a hormone produced by the pituitary gland inside the brain. This hormone is called human growth hormone or HGH. It is involved in many bodily functions, the most important of which is the development of the muscular and skeletal system. HGH enables the muscles and bones to grow fast. It facilitates growth especially during the adolescent years when it acts as regulators for tissue and muscle growth, energy levels, repairing cells and losing fat.

What role do anabolic steroids have (apart from cheating, and leading you into dangerous health waters!), and what’s all the stuff about exercise converts fat to muscle? as in do lipids actually ‘transform’ into protein, or is it actually that the exercise calls on the energy in the fat that therefore breaks down to release it to the active muscle cells?

Well if you excercise you burn energy, which can force the body to use some of it’s fat reserves. Also you will damage and therefore force regrowth of muscle. There isn’t a direct conversion, but the end result of excercise is less fat and more muscle.
Generally speaking aerobic excercise burns more fat (jogging, swimming etc), while anaerobic excercise builds more muscle (weight training, sprinting). More muscle requires more calories to maintain, hence if you are muscle bound you need to eat more just to maintain weight.
As you seem to have an interest in cancer it’s worth bearing in mind that muscle growth requires new blood vessels, it’s as though a message goes out through the body to get the machinery in place. As you are probably aware cancer has a similar need for new blood vessels. Weight lifters tend to avoid such things as drinking green tea because it reduces blood vessel pathways whereas in some early stages of cancer it is being recommended to reduce the risk of secondary cancers. I don’t know that there is evidence that weigh lifting increases cancer risk though.
