Skeletal System

Skeletal System

1. TYPES OF JOINTS

   • IMMOVABLE
     • No movement and the bones are fixed
       • Cranium
       • Pelvis
   • Slightly Moveable
     • The bones are linked by cartilage to allow for slight movement
       • Spinal Column
         • Ribs and sternum
   • Freely Moveable (Synovial Joints)
     • Ball and socket joint
       • Shoulder/hip
     • Hinge joint
       • Elbow/knee
     • Saddle Joint
       • Thumb
     • Pivot Joint
       • Neck
     • Condyloid Joint
       • Wrist-where the radius/ulna and carpals meet
     • Gliding Joint
       • Wrist-between the carpals

2. The 8 body systems

   • Digestive System
   • Respiratory System
   • Muscular system
   • Nervous System
   • Skeletal System
   • Hormonal System
   • Circulatory System
   • Excretory System

3. Types of bones

   • Long
     • ulna
     • Humerus
     • Femur
   • Short
     • phalanges
   • Flat
     • Cranium
     • Ribs
     • Pelvis
   • Irregular
     • Patella
     • Carpals
     • Vertebrae

4. Functions of skeleton

   • Protection
     • ribs protect the heart and lungs
   • Shape
     • Gives shape to the body
   • Support
     • Holds vital organs in place provides a place for the attachment of muscles
   • Blood production
     • Red and white blood cells are produced in the bone marrow
   • Movement
     • Muscles pull on the skeleton to cause movement. movement occurs at the joint
