Skeletal Anatomy

Skeletal System ● Axial Skeleton vs. Appendicular Skeleton Axial Appendicular

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) ● Includes: Rear Legs and Pelvic Bones ● Bones: ● femur (upper leg bone) ● tibia and fibula (lower leg bones) ● tarsals (hocks) ● metatarsals (feet) ● phalanges (toes) ●

Skeletal System – Structure & Purpose ● Purposes: ● protect vital body organs and give form or shape to body 1. 2. 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
