Function of the

skeletal system

P1

Functions:2) Provides a framework for the body

1) Allows movement of the body as a whole and its individual parts

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!!

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.

4) Protection

3) Production of blood cells

Certain bones contain RED bone marrow, the bone marrow produces RED blood cells, WHITE blood cells and PLATELETS

The ‘certain’ bones are: Pelvis, Sternum, Vertebrae, Costals, Cranial bones and Clavicle.

Bones will support and protect the vital organs they contain.

What 4 examples can you think of???

6) Storage of minerals and fats

5) Attachment of soft tissue

Bones themselves are minerals stored within cartilage… acting as a mineral store for Calcium, Magnesium and Phosphorous.

Fats (triglycerides) are also stored within the YELLOW bone marrow.

Bones provide the surface for attachment of soft tissues, such as Muscles, Ligaments and Tendons.

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.

Types of bone:Long bones, Short bones,Flat bones, Irregular bones, Sesamoid bones

Functions:• Support• Protection • Attachment for skeletal muscle• Source of blood cell production• Store of minerals
