									The Skeletal System
Skeletal System Recap
Structure
a) axial (skull, rib cage, vertebrae)
b) appendicular (limbs)
Function – structural support,
protection, growth centre for cells,
reservoir for minerals, movement
Types of Bone – long, short, flat,
irregular, sesamoid
What is under the skin?
The Body’s Key Bones
     Cranium and Face Bones
        (Skull and face bones)
     Vertebral Column
        (Backbone or spine)
     Coccyx (Tailbone)
     Pectoral Girdle (collar bone,
        shoulder blade, humerus)
     Forearm (radius, ulna,
        carpals, metacarpals,
        phalanges)
What is under the skin?
The Body’s Key Bones

     Pelvic Girdle (pelvis)
     Femur (thigh)
     Patella (knee cap)
     Tibia & Fibula (shin)
     Tarsals,
       metatarsals,
       phalanges (foot)

 Bone Landmarks
  Special areas on bones that
   generally serve as attachment
   points for muscles, tendons
   and ligaments
