1. Function of the skeletal systemP1
Function
of the
skeletal system

2. Functions:
1) Allows movement of the body as a whole and its individual parts
2) Provides a framework for the body
Bones act as levers and by forming joints allows muscles to pull on them and create joint movements… so we can move in all directions and perform the functions we need on a daily basis.
The skeleton gives the body its distinctive shape and is the framework that which to attach muscles and other soft tissue.
Without a skeleton we would be a big bag of….
FLUID!!

3. 4) Protection What 4 examples can you think of???
Certain bones contain RED bone marrow, the bone marrow produces RED blood cells, WHITE blood cells and PLATELETS
Bones will support and protect the vital organs they contain.
What 4 examples can you think of???
3) Production of blood cells
The ‘certain’ bones are: Pelvis, Sternum, Vertebrae, Costals, Cranial bones and Clavicle.

4. 6) Storage of minerals and fats
Fats (triglycerides) are also stored within the YELLOW bone marrow.
6) Storage of minerals and fats
Bones themselves are minerals stored within cartilage… acting as a mineral store for Calcium, Magnesium and Phosphorous.
5) Attachment of soft tissue
Bones provide the surface for attachment of soft tissues, such as Muscles, Ligaments and Tendons.

5. Flat bones, Irregular bones, Sesamoid bones
Types of bone:
Long bones, Short bones,
Flat bones, Irregular bones, Sesamoid bones
1) Learners must describe the axial and appendicular skeleton.
2) The different types of bone in each of the skeletons and be able to locate all of the named bones stated in the Unit content (List).
3) They must also describe the function of the skeletal system.
