• Muscle: a tissue that contracts and relaxes to produce movement and force
• Bone: a hard, compact,living tissue that forms the framework of the body.
• Ligaments attaches one bone to another
• Tendon attaches a muscle to a bone.
• Cartilage: reduces friction and absorbs shock in joints allowing smooth movement of joint
• Synovial capsule: secretes synovial fluid that lubricates the joint to mantain stability.
• Synovial fluid: lubricates and nourishes joint
• Muscles have to work together to move a bone or joint. They can only pull when contracting not push.
• Antagonist pairs are muscles that work opposite. When one contracts movement happens while the other relaxes.
• Examples of antagonist pairs: biceps relax when quadriceps contract.
