§3.5 MOVING THE SKELETON

TEXTBOOK PAGES 116-123

§3.5 MOVING THE SKELETON

• I can explain how the skeleton can move: joints and muscles
• I can describe the 5 different joints, and give an example
• I can draw a joint and describe the parts of a joint
• I know what tendons and ligaments are
• I can describe what a muscle can do: only pull or contract
• I can explain why you need muscles as an antagonistic pair

p. 116-123

§3.5 MOVING THE SKELETON

• joints
• ball & socket joint
• hinge joint
• pivot joint
• Gliding joint
• fixed joint
• ligaments
• synovial joint
• synovial fluid
• arthritis
• tendons
• antagonistic pairs

p. 116-123

JOINTS

A joint is a place where two bones meet. This is also the place where your skeleton can move.

p. 116-123

TYPES OF JOINTS

Fixed - no movement, skull

Ball and socket- movement in all directions, hip/shoulder

Hinge- movement in 1 direction, elbow/knee

Pivot- turning movement, radius+ulna/neck

Gliding- glide over each other, wrist/backbone

p. 116-123

PART OF A JOINT

Ligaments: connect bone to bone

Tendon: connect bone to muscle

Synovial joint: ball and socket, hinge, pivot. Also have synovial fluid to oil the joint

p. 116-123

MUSCLES

Muscles work in antagonistic pairs, because muscles can only pull or relax. They need a partner (antagonist) to pull the opposite way

p. 116-123
