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 Red marrow Yellow marrow Compact bone Periosteum 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

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

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