chapter 15 Flashcards
exostosis
bony growth (benign) arising from the surface of bone
fracture
traumatic breaking of a bone
colles
fracture near the wrist at distal end of the radius
comminuted
bone is splintered and crushed into several pieces
compression
bone collapses or is compressed; occurs in vertebrae
Greenstick
bone is partially broken m; breaks on one surface and bends on another; ofteb occurring in forearm
impacted
one fragment is driven firmly into the other m; at the head of the femur or head of the humerus
osteogenic sarcoma ( osteosarcoma)
common malignant tumor arising from osteoblasts, found primarily in children and adolescents
osteomalacia
softening of bone, with inadequate amounts of mineral (calcium) in the bone
osteomyelitis
inflammation of the bone and bone marrow secondary to infection
osteoporosis
decease in bone density (mass); thinning and weakening of bone
talipes

joint ( articulation)
a coming together of two or more bones
suture joints
immovable joint
synovial joints
freely movable
joint capsule
surrounds the bones ina a synovial joint. IT is composed of fibrous tissue
ligaments
bone to bone
articular cartilage
a smooth, glistening white tissue that cover bones at the joint
meniscus
a crescent-shaped fibrocartilaginous structure that partly divides a joint cavity and acts as a protective cushion
bursae
closed sacs of synovial fluid lined with synovial membrane and are located near but not within a joint
tendon
muscle to bone
synovial cavity
space between bones at a synovial joint; contains synovial fluid produced by synovial membrane
synovial fluid
viscous (sticky) fluid with the synovial cavity. Synovial fluid is similar in viscosity to egg white; this accounts for the origin of the term
ankyl/o
stiff
arthr/o
joint
articul/o
