Humans And Animals Have Different Movement Systems

Humans and animals have different movement systems with plants, humans and animals can move part orall of his body, while the plants are not able to do that, the motion system in humans and animals made up of bones and muscles, bones locomotor referred to as passive, because just follow the control muscle, whereas muscle locomotor referred to as active, because it has the ability to contract, so as to move the bone, cooperation between the bones and muscles, resulting in movement that is consistent, flexibel, and no stiff like a robbot. Among other of the functions of bones is to support frame and supporting the establishment of the body, giving the body shape, protects vital organs such as the brain, heart and lungs, the muscles attach order, and the formation of blood cells and the accumulation of calcium.

Human skeletal disorder also can suffer, disturbances in bone and joints can be differentiated into fice categories, the first categories is the mechanical disorders, mechanical disorders can cause fissure, fracture, bruise joints, and explained joints. The second disturbances is a physiological disorder of bone, this disorder may result in hydrocephalus, mycrocephalus, osteoporosis, and rickets. A disorder that third attitude is wrong habits, such as lordosis, kyphosisi and scoliosis. The fourth disorder is joint problem, such as disiocation, sprains and artritis. And the last disorder is bone and joint infections, such as exudative arthritis, arthritis sicca, paralyzed joints, and necrosis.

While muscle is active locomotor, based of types, muscle can be differentiated into three types. First type is smooth muscle, cardiac muscle, and striated muscle, muscles work in pairs to produce motion, muscle pairs work againts, each other, and their end is the antagonist muscle, working antagonistic muscle can cause several types of motion such as extension, abduction, depression, and supination, muscle can also disorders such as cramps or spasms, tetanus, polio, muscular hypertrophy and abdominal hernias.
