Skeletal SystemAxial Skeleton vs. Appendicular Skeleton

AxialAppendicular

Axial Skeletal SystemIncludes:Vertebral columnRibs SternumSkullAppendicular Skeletal SystemPectoral limb (front limbs)Includes:Shoulders, Legs, FeetBones: Scapula/shoulder bladeHumerus/armradius and ulna/forearmcarpals, metacarpals andphalanges (toes)Pelvic limb (rear limbs)Includes:Rear Legs and Pelvic BonesBones:femur (upper leg bone)tibia and fibula (lower leg bones)tarsals (hocks)metatarsals (feet)phalanges (toes)

Skeletal System Structure & PurposePurposes:protect vital body organs and give form or shape to bodySkull protects brain, ribs protect lungs and internal organsSpinal column or backbone protects the spinal cord and provides shape to the animal.Structure:consist of bones, cartilage, and joints

Avian (Bird) Skeletal SystemVery uniqueLightweight, thin, hollow bonesMost skull bones elongate toward the front of the head.Some have skulls with an upper beak fused to itOther birds are hinged on both upper and lower (mandibles) giving it more flexibility
