Document Summary
Atlas of skeletal muscles by robert j stone. Movement = anchoring of muscles to generate movement around joints (provide levers) Support = provides shape (allows adapting and navigation of environment) Ca2+ regulation (nervous response e. g. muscle contraction) Relatively rigid objects that may be made to rotate about an axis by the application of force. Effort (applied force in order to generate movement) = muscle. 1st class lever system = axis in the middle, resistance at one end and force at the other (seesaw or tucking the chin) 2nd class lever system = axis at one end, resistance in the middle and force at the opposite end to the axis (going up onto tiptoe) 3rd class lever system = axis at one end, resistance at the other and force in the middle. Bone is made up of organic (35%) and inorganic components (65%) Matrix = mostly type 1 collagen to provide elasticity. Cells = osteoblasts, lining cells, osteocytes and osteoclasts.
