SUPPORT:All 206 bones in our body work together to support our body day by day.
Thevertebrae supports ourhead along with giving us a good back structure. Our leg bones are extremelystrong as they hold up our body weight to support our upper body. MOVEMENT:Our body is enables to move due to the fact our bones, muscles and joints work asone to allow us to walk, sprint and run.
In addition to this the Vertebrae is avital bone that allows us to bend, stretch and rotate our body. Our musclesproduce muscular contractions that cause our bones to move which results inphysical action. Our bottom jaw-bone is jointed to the cranium which enables usto perform a chewing process. PROTECTION:Many different parts of the muscular skeletal system protects different bodyorgans. The brain and its soft tissues are both protected by the Cranium whichis also known as the skull. In addition to this, the heart and lungs areprotected by our 12 pairs of ribs. A joint is where two bones fit into anotherbone which is rounded, the rounded shape holds the bone to be held securelywhich enables movement. Muscles are attached to our bones by something called atendon, a tendon is made up of strong fibrous tissue.
Similar to a tendon amuscle is a bundle of strong fibrous tissues. Muscles give our body powerfulbody strength e.g power to run. Theout-side layer of our bone is a thin closely compacted substance that holds ourblood and nerve vessels that supplies our bone with the right nourishment togrow and maintain health this layer is called the Periosteum. The next layer istypically known has the ‘hard’ layer, this is the layer you see on the humanskeleton. The next layer is made up of bones that are still very strong but notas hard as a compact bone, in addition to this this layer contains cancellousbones. Cancellous bones provides alayer of protection for the inner bone.
Inside the bone is bone marrow which issimilar to a thin jelly substance, its job is to produce blood cells. Almostevery bone in our body is produced of the same thigs. Themuscular skeletal system is known for its protection and its support andmovement. The muscular skeletal system is made up of our body’s larger bonesand muscles in addition to this our joints such as elbows and knee caps arepart of this system too as they allow movement in our body. The muscularskeletal system gives our body good structure, without the muscular skeletalsystem our body would be all flabby and out of shape and vital organs will notbe protected.
Our actual bones are made up of hard bone, soft bone and bonemarrow.
