Motion Systems Biology - The material of this time is devoted to biological motion systems in general , so that we better understand the system better motion . Primarily on human motion system consists of a wide range of tools that work in continuous motion and can not be separated from each other .
Have you ever noticed, how our bodies can have a shape like this ? Your body can have a form because it has a motion system . The motion system consists of bones , joints , and muscles . All three work together to form a system of motion . Motion system is this that gives the body shape , the tool motion , road , and ran as well as perform various activities lainnya.Tulang , muscles , and joints , all three come together to form a single unit and have different functions . Bone is a means of passive motion . Bone can not be moved if there is no muscle . Locomotor muscles is said to be active . These muscles that move the frame . In everyday life , this is called muscle meat . The joint is the liaison between bones in the body .
One of the characteristics of living things are moving . In general, the motion can be interpreted on the move or change the position of part or all parts of the living body . Living things will move when aka impulses or stimuli that affect some or all parts of his body . In animals and humans may represent a general sense of motion and can be seen with the naked eye / real . Motion on humans and animals are composed using the tool motion in the motion system .
As for the plants , which do not move will be seen by the naked eye because it occurs in an organ or plant cells . Thus can not be equated sense of motion in all living things . Motion in plants also involve locomotor , locomotor used but depends on impulses or stimuli on cells / tissues / organs of the plant . Discussion of motion in plants will be detailed in the next chapter in the upcoming semesters .
locomotor
Motion tools used on humans and animals there are 2 kinds of locomotor passive form of bone and locomotor muscles active form . Both of these locomotor will cooperate in doing the movement so as to form a system called motion system .
The bones are called passive because locomotor bone can not do pergerakkannya own . Without the active locomotor attached to the bone , the bones in humans and animals will be silent and not able to form a real movement of the tool . Although it is a means of passive motion , but the bone has a major role in the system of human and animal motion .
Called active locomotor muscles because muscles have chemical compounds which are proteins actin and myosin are joined together to form aktomiosin . With this aktomiosin muscles can move . So when the muscles attached to bones and move the bones will also move automatically .
By having this aktomiosin then the muscle has a flexible nature / flexible and have the ability to shorten the muscle fibers ( during contraction ) and elongate the muscle fibers ( at the time of relaxation / back to its original position )
