3

Functions of the skeleton

-support and shape
-movement
-protection

4

Support and shape

The bones of the skeleton keep the body upright and give it shape

5

Movement

Bones move when muscles contract to pull on a bone

6

Protection

The skeleton protects organs, for example: the skull, protects the brain

7

Joints

Joints -> where bones meet

1: fused joint
2: freely moving joint

8

Fused joint

No movement between bones. For example: skull

9

Freely moving joints

Ball and socket joints. For example: hips.

Hinge joints. For example: knee

10

Synovial fluid

A liquid that oils the joints and allows it to move freely

11

Cartilage

Protects the end of the bone and reduces friction in the joint

12

Muscles

Muscles allow bone movement
They are made of protein
They contract (tighten) and relax to move parts of the body.

13

Tendons

Join muscle to bone

14

Ligaments

Join bone to bone

15

Antagonistic Pair

Two muscles which carry out opposite effects

16
