Document Summary
Baker | fors 3331 | spring 2017 | lecture 2 | page 1. Muscle origin - attachment that is more stable during contraction: usually proximal (closer to trunk) in the limbs. Muscle insertion - attachment that is more mobile: moved by contraction, usually distal (away from the trunk) in limbs. Joint - connection between skeletal elements: bones articulate at joints. Ligaments - connect bone to bone at joints: cords, bands, or sheets of collagen bundles, control/limit movement at joints. Tendons - connect muscles to bone: bundles of collagen fibers. Cartilage - tough, dense, elastic, compressible connective tissue. Freely moving joint: knees, fingers, elbows, toes. Hyaline cartilage - thin layer of cartilage that occurs in synovial joints. Joint cavity - area between bones in a joint: space lined by a membrane that secretes synovial fluid (lubricant) Joint capsule - sac of connective tissue attached to articulating bones: encloses the entire joint in synovial fluid.
