bones which do not fall into any other category TYPES OF BONES Long Bone Short Bone Support, strong As wide as they are long Flat Bone Irregular Bone Provides Protection bones which do not fall into any other category

Skeletal Joints Where 2 or more bones come together Ball and Socket: allows for greatest movement – hip, shoulder Gliding: surfaces slide over one another – wrist, ankle, thumb (saddle joint) Hinge: movement on one plane – elbow, knee, fingers, toes Immovable/Suture: provides for growth not movement – cranium Pivot : bones spin and twist around other bones neck, radius of elbow

Types Of Joints Pivot Hinge Ball & Socket Gliding Top of the neck Elbow/Knee Ball & Socket Gliding Intercarpal joints Shoulder/Hip 5

Ligaments (Red) Type of connective tissue “ties” bones together

Tendons Type of connective tissue Attaches muscles to bones

Cartilage On end of bones provides cushion and keeps bones form grinding against each other Damaged or lack of cartilage can cause arthritis – can be very painful and limit motion
