Skeletal System

Human beings are chordates, and like all chordates they are vertebrates. They are members of the class mammalia and have a skeleton made of true bone.

• Muscles are attached to bones with a connective tissue called tendons which are found at the end of a muscle and attach to the bone.
• Tendons provide stabilization during muscle contractions.
• Joints are places in the skeleton where bones meet . Ligaments are connective tissues that attach bones together within joints, and serve to stabilize the joints while allowing for flexibility.
• In general bones protect your organs and provide the framework for movement. When you perform weight bearing activities (ex: lifting weights), your bones add more bone tissue and increase their bone density, which is important to avoid breaking or porous bones.
