Document Summary
Body motion w/o regard to torques or forces that produce motion. Linear motion where all body part move parallel to and same direction as every other body part. Rigid body moves in circle path around pivot point. All body points simultaneously rotate in sam angular direction. Motion of bones relating to sagittal, frontal and horizontal planes. Push or pull that produces, stops or modifies movement. Gluteus max- agonist of open chain hip extension. Gluteus medius and hip abductors - neutralizers spinal/core muscles - stabilizers. Mechanical device that converts force to torque. Distal end of bone and muscle has more leverage. Elongated convex matches up with elongated surface. Convex on concave surface at right angles. Like ball and socket but shallow concave surface. Ex. hyaline cartilage flexible , maintain shape. Water saturated substance where collagen, elastin and cells are located. Capsule, ligs, high type 1 collagen, low elastin, low ground substance. Ct that surrounds bundles of muscle fibers.
