They are called skeletal muscles because they are almost always found attached to the skeleton and produce movements in different parts of the skeleton. Smooth Muscles: Smooth muscles form the soft body organs like stomach‚ intestine‚ blood vessels etc. They are not under the will of human beings and are responsible for unconscious body activities like digestion of

“Some coral species lose their skeletons altogether” (Fine & Tchernov‚ pg 9‚ par 4)‚ “and skeletal growth of recent recruits can be disrupted” (Cohen‚ pg 9‚ par 4). So the disruption of the skeletal growth can then make the reefs weaker and more vulnerable to damage and destruction. The acidity of the ocean doesn’t just effect the skeletal growth of the coral reefs either. “This is damaging many ocean species that use calcium carbonate to form their skeletons and shells. Studies have shown that

osteogenesis (aka bone distraction) can be used to widen the jaw by gradually moving the bones. IS DISTRACTION OSTEOGENESIS A NEW TREATMENT METHOD? Since 1903‚ bone distraction has been used to successfully manipulate the long bones of the human skeleton. Then‚ in the 1950s‚ Dr. Gabriel Ilizarov worked to perfect the method to address deformities and correct defects of the extremities. Initially‚ for the most part‚ Dr. Ilizarov’s work went unnoticed until he presented his distraction osteogenesis
