Transcript of The skeletal system

FUNCTIONS OF THE SKELETON
The Skeletal system
PROTECTION
Without the Skull our Brains would be open to every collision and impact.
SUPPORT and SHAPE
MOVEMENT
BLOOD PRODUCTION
200 billion blood cells per day
HOW MANY BONES DO YOU KNOW?
HOW DO WE MOVE?
JOINTS
PLENARY
To be able to:
Describe the structure of the skeleton
LEARNING
OUTCOMES:
GOOD LEARNING:
Know and correctly
IDENTIFY
the location of the major bones in the Axial & Appendicular Skeleton.

GREAT LEARNING:
Produce a
CORRECTLY
labeled skeleton with all the bones from the List.

EVEN BETTER:
DESCRIBE
the different types of bones (FISSL)
AXIAL SKELETON
Appendicular
skeleton
126 bones
Nominate a person in your group to be a human skeleton.
Using the labels provided, attach them to your skeleton to show where each bone is located in the human body.
Pelvis and Vertebrae:
Sacrum
Ilium
Ischium
Pubis
The Vertebral Column
Coccyx Vertebrae (5)
Sacrum Vertebrae (5)

Lumbar Vertebrae (5)

Thoracic Vertebrae (12)

Cervical Vertebrae (7)
Support the head, allowing it to bend and twist.
The ribs are connected to these - there is very little movement.
These are big and allow powerful twisting and bending of the back.
These form one solid mass which is fused to the pelvis.
These are the remains of our tail.
Progress check:
Can you/have you.......
1. Describe what the Axial and Appendicular Skeletons are.
2. Produced a
CORRECTLY
labeled skeleton with all the bones from the List.
3.
DESCRIBE
the different types of bones (FISSL)
LESSON OBJECTIVE:
Describe the function of the skeletal system
GOOD:
You can
DESCRIBE
the different types of bones there are in the human body.
GREAT:
You can
DESCRIBE
how the Skeleton provides support, shape and movement.
EVEN BETTER:
You can
DESCRIBE
how bones produce blood and store minerals.
Watch the first 2 minutes of the clip and make notes on the Functions of the Skeleton
The hard nature of bone means that the skeletoncan protect the more delicate parts of the body.
The skeleton provides a surface for your muscles to
ATTACH
to.
TENDONS
attach muscles to bone, these muscles pull on the bone and this creates movement.
Joints are classified depending on the amount of movement they allow:

FIXED JOINTS
SLIGHTLY JOINTS
FREELY (SYNOVIAL) JOINTS
FIXED JOINTS:
SLIGHTLY MOVABLE:
The ends of these bones are covered in a smooth articular cartilage which is separated by pads if fibrocartilage.
Slight movement is possible because the pads of cartilage compress.
FREELY MOVABLE
(SYNOVIAL) JOINTS:
TYPES OF BONES:

TASK:
Complete the Types of Bones Worksheet on:
PupilsShared - PE - GCSE PE - Types of Bones.

The

BLACK

writing is to help you and the
RED
writing is things you

MUST

find the answer to.

When this is complete swap with your partner and fill in a G4G form on their work.

The skeleton is not completely solid.
Blood cells feed the center of the bones and within this is bone marrow.
This is essential as 200 million red blood cells die in our bodies every day,
RESEARCH TIME:
There are 6 main classification of joints, these are:
Hinge
Ball and socket
Ellipsoid (Condyloid)
Gliding
Pivot
Saddle

You need to produce a piece of work that
DESCRIBES

1. What these joints are.
2. Where they are found.
3. What types of movement they can perform, eg extension, flexion etc...
Show me the answer
THUMBS
UP
IF YOU THINK THE STATEMENT IS
TRUE
THUMBS
DOWN
IF YOU THINK THE STATEMENT IS
FALSE
A Regular Bone is the correct name

Leg squat exercise is the best example of hinge joints at work?
Rest and recuperation is a function of the skeleton
Tendons join muscles to bones.
STARTER:
What bones do you already know?

On your Post – it Notes write down any names of bones you know.

After the register you are going to take part in a quick fire quiz on the skeleton
Get your books out and revise your bones
Questions to answer:
a) Identify one functions of the skeleton (1 mark)
b) Describe what this functions is. (2 marks)
c) Give an example WHY they might be needed in sport? (2 marks)
Brains in Gear
Hand your books TO YOUR PARTNER.
Using you green pens mark your partners work.
a) Could have any of the following;
Movement
Support
Protection
Blood Production
b) Protection - The hard nature of bone means that the skeleton can protect the more delicate parts of the body.
Support - Without the skeleton, the body would be floppy and shapeless. Therefore, the skeleton provides a frame for our muscles and organs.
Movement - The skeleton is jointed to allow us to move whenthe muscles attached to them contract.
Blood Production - Red and white blood cells are made in red bone marrow which is found at the ends of the femur and humerus and in the ribs, sternum, pelvis and vertebrae.
