LARGE ANIMAL SKELETAL SYSTEMS Functions of the Skeletal

Functions of the Skeletal System • Form • Protection • Support • Strength

How does it work? • Bone- Hard tissue that supports and protects other organs

Bones • Spongy bone • Fills ends of bones and lines hollow portions •

Joints (Vertebrae/Back) Plane Joints Ball&Socket Joint (Hip) Pivot Joint (Neck) Hinge Joint (Stifle)

Parts of the Skeleton • Axial - central axis bones • Pectoral - bones

Bones of the Axial Skeleton • Skull • Maxilla • Mandible • Vertebrae •

Bones of the Pectoral Skeleton • Scapula • Humerus • Radius • Ulna •

LARGE ANIMAL SKELETAL SYSTEMS

Functions of the Skeletal System • Form • Protection • Support • Strength

How does it work? • Bone- Hard tissue that supports and protects other organs • Cartilage- Firm, flexible tissues that is not as hard as bone • Ligaments- Tissue that connects bone to bone • Tendons- Tissue that connects bone to muscle • Joints- Where bones meet and allows for movement

Bones • Spongy bone • Fills ends of bones and lines hollow portions • Red marrow • Inside cavities of spongy bone, formation of red blood cells • Yellow marrow • Fat and energy storage • Compact bone • Layer of hard mineral matter, calcium, gives bones strength • Periosteum • Outer most layer, cushions the hard portion of the bone, repair of broken bones

Joints

Parts of the Skeleton • Axial - central axis bones • Pectoral - bones of the fore limbs • Pelvic - bones of the hind limbs

Bones of the Axial Skeleton • Skull • Maxilla • Mandible • Vertebrae • Cervical Vertebrae • Thoracic Vertebrae • Lumbar Vertebrae • Sacrum • Caudal Vertebrae Ribs • Sternum •
