Them Bones or….. The Human Skeleton

Main Parts of Human Skeleton

Location of main bones

Functions of skeleton  Support  Movement  Protection

Can you remember? What are those three functions? Support Protection Movement Hold us upright Ribs protect the lungs heart etc Anchor for the muscles

Getting about…. Movement

Bones and muscles of the arm biceps radius humerus ulna

How would YOU raise the arm? biceps radius humerus ulna

Muscles work in pairs (antagonistic pairs) bone pulled upward triceps relaxes

How would you lower the arm? biceps triceps ulna radius humerus

They are called an antagonistic pairs bone pulled downward biceps relaxes

Watch the muscles….

They only contract

They can not push

They only pull

That’s why they work in pairs

They are called an antagonistic pairs

A Synovial Joint Bone Ligaments hold the bone together Cartilage protects end of bone Synovial fluid stops wear Capsule Membrane

Connective Tissue Tendon Muscle to bone Ligament bone connected to bone Cartilage protects end of bone

A Joint is where the bones are allowed to move about each other, this is called a hinge

Bone Marrow  Red blood cells are made in the marrow or inside of the bones

Can you remember? How many functions does the skeleton have? 3

Can you remember? What are those three functions? Support, Protection and Movement Tendon, Cartilage and ligament Joints types – Ball and socket, hinge, pivot and fused
