How does the body differentiate different muscle tissue?
Q. How does our body know to differentiate which tissue cells makeup bicep versus tricep muscles? Since the muscles are located at different parts of the body, and have different uses, how would heart muscles play into the equation? Or are specific types of tissues modified slightly by the body based on the location and need?

A. This is a very complex issue. The patterning of what goes where in our bodies (not just different muscles, but everything: blood vessels, veins, bones, intestines, organs, and so on) is done during development in the womb. The processes by which these decisions are made, and our body pattern decided is NOT well understood as yet - but there is a lot of research going on into the area. For an idea of some - try looking up the effects of retinoic acid on chick limb development.

A. what is making the heat? in Thermochemistry, there a 2 type of reaction. one is endothermic reaction & another one is exothermic reaction. exothermic reaction will produce heat when the reaction occur. well, in our body, the oxidation of glucose occur in mitochondria in order to obtain energy in form of ATP. the oxidation of glucose molecule is a exothermic reaction. this is how our body make heat! have a nice day.

A. I think you should go check out Ask your questions there and you will get a ton of useful info. I say stick to compound movements like squats, bench press, chins deadlifts. Lift with intensity. Lifting is only part of it, as diet and rest is just as important. Stick to three days a week. Tone is dictated by bodyfat not how many bicep curls you can do. Build the muscle that you want to show off and then lose the bodyfat to reveal and show it off.
