1Function of the skeletal system P1Functionof theskeletal system
2Functions:1) Allows movement of the body as a whole and its individual parts2) Provides a framework for the bodyBones 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!!
34) 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 PLATELETSBones will support and protect the vital organs they contain.What 4 examples can you think of???3) Production of blood cellsThe ‘certain’ bones are: Pelvis, Sternum, Vertebrae, Costals, Cranial bones and Clavicle.
46) Storage of minerals and fats Fats (triglycerides) are also stored within the YELLOW bone marrow.6) Storage of minerals and fatsBones themselves are minerals stored within cartilage… acting as a mineral store for Calcium, Magnesium and Phosphorous.5) Attachment of soft tissueBones provide the surface for attachment of soft tissues, such as Muscles, Ligaments and Tendons.
5Flat bones, Irregular bones, Sesamoid bones Types of bone:Long bones, Short bones,Flat bones, Irregular bones, Sesamoid bones1) 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.Location of major bones:CraniumClavicleRibsSternumHumerusRadiusUlnaScapulaIliumPubisIschiumCarpals & Metacarpals & PhalangesFemurPatellaTibiaFibulaTarsals & MetatarsalsVertebral column – (cervical, thoracic, and lumbar vertebrae, sacrum, coccyx)Functions:SupportProtectionAttachment for skeletal muscleSource of blood cell productionStore of minerals
