What are the functions of the Musculoskeletal System?
support storage (minerals (calcium) and lipids) blood cell production protection leverage
Epiphysis
enlarged area at either end of the bone
Diaphysis
long shaft in the middle portion of the bone
Metaphysis
joining point between the epiphysis and diaphysis
Periosteum
fibrous covering around the outside of the bone not covered with articular cartilage
Endosteum
fibrous and cellular tissue lining the medullary cavity of the bone
What are the Long Bones?
humerus, radius, femur, tibia, metacarpals, metatarsals

What are the Irregular Bones?
vertebrae and certain facial bones
What are clinical signs of Long Bone Fractures?
swelling lameness edema pain non weight bearing deformity (large range of motion, abnormal) history of abuse
How do you classify fractures?
- type (spiral, comminuted, salter-harris)
- location (mid-diaphysis)
- position of fracture fragments
What are the types of Incomplete Fractures?
greenstick
fissure
depression
What are the types of Complete Fractures?
transverse
oblique
spiral
comminuted (multiple pieces, fracture lines connect)
