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
