The heft tissue has four main properties; Excit baron, Contractibility, Extensibility and snap. Excitpower; The ability to answer to stimuli. Contractibility; The ability to contract. Extensibility; The ability to stretch without causing a tear. Elasticity; The ability to be able to return to typical shape. small-arm contraction is taking place the muscular corpse performs 3 functions; Motion, Heat Production and Maintenance of posture. Motion; The ability of be able to move e.g. walking or running. However, with head you mustiness know about levers. The framework of the personate is cover in muscle which permits movement. When moving or lifting a intemperate load, its easier to use levers, and in the body its the rent alike(p). each levers use 5 diametrical parts; Lever, Fulcrum, ponderousness squelch, resistant wildness and Torque. Lever; almost always the bone Fulcrum; the stick point of the lever in which is usually the joint. Muscle deplumate; the pull up that drives the opposite ends of the muscles to contributeher. Resistive force; the force generated by a factor to the external body Torque; the layer in which a force tends to rotate an object. hypertext transfer protocol://www.answers.com/topic/first-class-lever http://www.answers.
com/topic/first-class-lever There are three different types of levers in the body; First-class, Second-class and Third-class. First-class; when the muscle force and repellent force is on different slopes of the fulcrum e.g. the head resting on the vertebral column. As the head is raised, the facial portion of the skul l is the resistance, the fulcrum is in the ! midst of the book of maps and occipital bone, and the effort is the contraction of the muscles of the back. Second-class; when the muscle force and resistive force act on the same side of the fulcrum, with the muscle force acting through the take continuing than that through which the resistive force acts - e.g. raising the body up onto the toes. The body is the resistance, the ball of the foot is the fulcrum, and the effort is...If you indirect request to get a full essay, order it on our website: OrderCustomPaper.com
