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
The Human Condition (Magritte) The Human Condition (Magritte) The Human Condition (La condition humaine) generally refers to two similar oil on canvas paintings by the Belgian surrealist René Magritte. One was completed in 1933 and is in the collection of the National Gallery of Art in Washington DC. The other was completed in 1935 and is part of the Simon Spierer Collection in Geneva, Switzerland.
