The Skeletal System Lesson 3 by Jim Alton
Objective Name the classification of bones Diagram the interior of a bone Explain how bones and muscles attach Define and List the main types of joints Identify and Label the movable joints
Bone Classification LONG BONES SHORT BONES FLAT BONES IRREGULAR BONES
Strong and Light The tubular shape of most of the bones in your body make the bones strong, yet light.
Structure of Bones PERIOSTEUM – Tough outer membrane (pĕr'ē-ŏs'tē-əm) ARTICULAR CARTILAGE – Smooth jointed surface COMPACT BONE – Thick layer beneath periosteum SPONGY BONE - Inside Layer BONE MARROW Red marrow – (blood cells) Yellow marrow – (energy reserve – can be converted to red marrow)
Getting Connected – Bone to Bone Ligaments – tough fibrous band of connective tissue that holds bones together.
Getting Connected – Muscle to Bone Tendons – a tough band of fibrous connective tissue that connects muscle to bone, or muscle to musclefibrous connective tissuemusclebone
Joints Between Bones Joints make movement possible Each kind allows movement in a different way
Ball and Socket Joints
How about a Quiz?
