1. Skeletal Anatomy

2. Skeletal System Axial Skeleton vs. Appendicular Skeleton Axial

3. Axial Skeletal System
Includes:
Vertebral column
Ribs
Sternum
Skull

4. Appendicular Skeletal System
Pectoral limb (front limbs)
Includes:
Shoulders, Legs, Feet
Bones:
Scapula/shoulder blade
Humerus/arm
radius and ulna/forearm
carpals, metacarpals and
phalanges (toes)
Pelvic limb (rear limbs)
Rear Legs and Pelvic Bones
femur (upper leg bone)
tibia and fibula (lower leg bones)
tarsals (hocks)
metatarsals (feet)

5. Skeletal System – Structure & Purpose
Purposes:
protect vital body organs and give form or shape to body
Skull protects brain, ribs protect lungs and internal organs
Spinal column or backbone protects the spinal cord and provides shape to the animal.
Structure:
consist of bones, cartilage, and joints

6. Avian (Bird) Skeletal System
Very unique
Lightweight, thin, hollow bones
Most skull bones elongate toward the front of the head.
Some have skulls with an upper beak fused to it
Other birds are hinged on both upper and lower (mandibles) giving it more flexibility
