Lesson 3
Bones & movement
Objectives:
Know the names of important bones in the human body.
Be able to identify different types of joint.
Be able to explain how bones, muscles and other tissues work together to allow us to move.
PART A
Watch this video about bones, muscles and movement.
PART B
Watch this experiment testing the strength of bones.
PART D
Watch this video about joints. Try to answer the questions at the end of the video.
PART E
Read this paragraph carefully.
The skeletal system is a body system made up of bones along with cartilage, ligaments and tendons. There are 206 bones in an adult human body, which make up the skeleton. Bones is a living tissue that can grow and repair itself. The skeleton has four functions: support, protection, movement and the production of red blood cells.

Without the support of the skeleton, the body would be completely floppy and limp. Having a skeleton gives the body support and holds the organs in place.

The skeleton protects the organs because bones are strong and hard. The rib cage protects the lungs and the heart. The vertebrae of the spine protect the nerves of the spinal column.

Muscles attach to bones by tendons and this allows the bones to move when the muscles contract. Where two bones meet there is a joint.
