 18. There are actually three types of muscle in the human body, which are skeletal, cardiac, and smooth. The skeletal muscles are, as you would have guessed, are attached to the bones by tendons. The role of these guys is to move the skeleton (i.e. walking, swinging your arms, or turning your head), to help us maintain posture while sitting or standing, and in a general sense, to create force through movement. These muscles can be controlled both consciously and unconsciously, and make up about 42% of the average man's body mass and 36% of the average woman's.

19. The cardiac muscles are found only in the heart (hence the name). Although these muscles resemble skeletal muscles in structure, they operate on a completely involuntary basis, which is why we don't have to command the heart to beat--it just does! And last, but not least, we have the smooth muscles, which are contained mostly in the walls of organs. This type of muscle also moves on an involuntary basis. For instance, when food is pushed along through the intestines, these muscles are working within the intestines and without our conscious effort.

20. Although most of us have heard that the tongue is the strongest muscle in the human body, this is simply not true. 1) Because the human tongue consists of sixteen different muscles, not just one, and 2) because there are simply too many different ways to determine "strength". If we were to try to determine the strongest muscle based off of the amount of work that the muscle does over its lifetime, the heart would take first place. However, if we were to say that strength should be measure on a "pound for pound" scale, the uterus would likely take the gold. But, if we want to determine the strongest muscle in terms of how much raw force it can exert, it would be the jaw muscle.

21.  The biggest muscle is the GLUTEUS MAXIMUS in the buttock:

22.  The smallest the STAPEDIUS deep in the ear. It is thinner than cotton thread.

  4. 27. 5 more facts about muscles

  They are made of muscle cells called myofibers. Each myofiber is covered in fascia.   

  Muscles use calcium to trigger contractions. They use ATP for energy. They have  

  contractile units called sarcomeres.
