Biomechanics is a field that examines the mechanics of biological structures, including bones, joints, and various forms of motion such as walking, swimming, and flying. It also involves studying the mechanics and movement of cells, particularly the cytoskeleton. Key clinical applications include the development of prosthetic materials and understanding how cancer cells navigate in and out of the bloodstream. The discipline encompasses a wide range of topics, highlighting its relevance in both health and biological research.
