Nankali's Masticatory Force Systematization force of the masticatory system and discovered the differences in the produced force, which was approximately doubled. The periodontal system controls automatically the measure of mastication force in this process and the jaw elevator muscles develop the main forces used in mastication. Dr. Weber worked out that 1 cm cross section surface area of any masticatory muscle can produce approximately 10 kg force. The following average surfaces were found: temporalis - 8 cm, masseter - 7.5 cm, and medial pterygoid - 4 cm which makes a total of 19.5cm. However, this force in some people is measured up to 3900N
In vitro muscle testing the level which ensures maximal motor unit recruitment. The servomotor can be programmed to maintain a given force while allowing the muscle to change length, vice versa, or the muscle may be subject to more complex testing, such as in work loops. When pennate muscles are used, sonomicrometry is often used to accurately determine fiber length during the test. "In vitro" muscle testing can be done on any scale of muscle organization - entire groups of muscles (provided they share a common insertion or origin, as in the human quadriceps), a single muscle, a "bundle" of muscle fibers, a single
