What are the 4 types of bones?
-long bone : longer than they are wide •fibula , tibia
-short bones : long as they are wide
•carpals , tarsals
-flat bones : are flat and strong (protection)
•Scapula , cranium
-irregular bones : unusual in appearance ( protection and attachment)
•vertebrae, mandible (jaw)

Name the bones in the feet and hand
Feet
- metatarsals

- talus
- phalanges
Hand
- metacarpals
- carpels
- phalanges
Name the hip bone
Pelvis
Name the types of joints
Ball and socket
Hinge
Pivot
Name the ball and socket joints
-allow most movement to all joints
Hip
Shoulder
Name the hinge joints
- flexion and extension is the only movement possible
- similar to a hinge on a door
Elbow
Knee
Ankle
Name a pivot joint
Neck
-one bone rotates around another
Define the term ‘flexion’
Decreasing the angle at a joint
For example a bicep curl
Define the term ‘extension’
Increase in the angle of a joint
For example throwing a ball or a shotput ball
Define the term ‘adduction’
Movement of a joint towards the midline of the body
For example doing a star jump
Define the term ‘abduction’
Movement of the joint away the midline of the body
For example doing a star jump
Define the movement ‘rotation’
Moving of a limb in a circular motion in either direction
For example in golf when doing a drive shot
Define the term ‘circumduction’
this is where the limb moves in a circle. This occurs at the shoulder joint
For example when the arm is held straight at the elbow and the arm from the shoulder to the fingertips are moved in circles
For example over arm serve in tennis
Define the term ‘planter flexion’
Movement at the foot downwards towards the sole
For example pointing your toe in ballet
Define the term ‘dorsiflexion’
Backwards flexion of the foot
For example when walking bending your foot up
What’s the role of a ligament
To connect bone to bone
-are very strong
What’s the role of a tendon
Connect muscle to bone
Where is the muscle deltoid
•In your shoulder
Creates abduction at the shoulder and raise your arms sideways for example swimming
Where are the pectorals
•The front of the body in your chest
Creates adduction at the shoulder across the chest e.g. press up
