Skeletal system
Introduction
The skeletal system includes bones, joints, cartilages and ligaments. The joint give the body flexibility and allow movements to occur. But from structural point of view, the human skeletal system consists of two main types of supportive connective tissue, bone and cartilage. The Adult human skeletons have 206 bones.
Functions of the skeletal system
- Support: it forms the internal framework that supports and anchors all soft organs.
- Protection: bones protect soft body organs.
- Movement: skeletal muscles attached to the skeletal system use the bone to levers to move the body and its part.
- Storage: fat is stored in the internal cavities of bones. Bone it self-serves as a storehouse of minerals. The most important being calcium and phosphors.
- Blood cell formation: it occurs with in the marrow cavities of certain bones.
- Triglyceride storage: Yellow bone marrow consists mainly of adipose cells, which store triglycerides.
