BIO202H5 Lecture Notes - Lecture 6: Tibiotarsus, Skeletal Muscle, Gastrocnemius Muscle
Document Summary
Using feet to propel into an environment. Thigh and leg muscles, skeletomuscular (helps generate and control locomotion) Control of the walls of the hollow organs and passages . vessels (involuntary) In the heart for pumping blood throughout the body and maintaining blood pressure. Attach to the hard tissue (bone or exoskeleton) Muscle generates force at the insertion point. Contraction of these muscles moves parts of hard tissue to general motion. Bringing the insertion point closer to the origin point. Class 3 lever (most common lever system in body - humans) Load, and force on the same side of fulcrum. The force is the insertion point beyond the knee joint generating force to lift the leg. Force / effort closer to fulcrum than load. The load and force are on the opposite sides of the fulcrum. If comparing class 1 vs class 3.
