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 muscle
Joints Between Bones
Joints make movement possible Each kind allows movement in a different way
Ball and Socket Joints
Hinge Joints
Gliding Joints
Pivot Joints
Fixed Joints
