Skeletal Anatomy
Skeletal System Axial Skeleton vs. Appendicular Skeleton Axial
Axial Skeletal System Includes: Vertebral column Ribs Sternum Skull
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)
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
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
