Bone Anatomy
Epiphysis
Long Bones
Laceration
simple/closed fracture
connects bone to bone
ligament
Contraction with no movement at the joint
Isometric
The shaft of a long bone
Bones of the skull, pelvis, and shoulder blade
Puncture wound
A fracture that does break through the skin
Compound/Open fracture
connects muscle to bone
tendon
Contraction where the muscle is shortening in length while maintaining tension
concentric isotonic contraction
Where the growth plate is found
Metaphysis
Bones of the spine
Irregular Bones
cut with clean edges
incision
incomplete fracture of the shaft of a bone
greenstick fracture
Comprised of the skull, spine, and ribcage
Axial skeleton
contraction where the muscle is lengthening as it maintains tension
eccentric isotonic contraction
Takes blood supply to the bone
Haversian Canals
bones of the foot and wrist
Short Bones
wound where a chunk of skin/tissue is completely removed, or hanging on by a small piece
Avulsion
a breakdown in the bone tissue caused by repeated stress or overuse
stress fracture
comprised of the arms, legs, pelvis
appendicular skeleton
four characteristics of skeletal muscle
Excitability, Extensibility, Contractibility, Elasticity
covers the ends of bones
articular cartilage
Imbedded in a tendon
Seasmoid
scrape on a rough surface
Abrasion
classification system for growth plate fractures
Salter-Harris
small fluid filled sacs that serve to reduce friction and add cushioning around joints
bursae
Prime mover of a movement
Agonist
outer lining of a bone
periosteum
biggest sesamoid bone in the body?
patella
caused by a blow with a blunt object that does not break the skin
Healing time for fractures
6-8 weeks
injury to a ligament
sprain
muscle that a opposes the action being performed. this muscle has to extend and yield to the motion
