Unit 4 Vocab Flashcards
the bones of the body’s appendages; the arms and legs
Appendicular Skeleton
dense, white, connective tissue that covers the articulating surfaces of bones at joints
Articular Cartilage
a fracture caused when a tendon or ligament pulls away from its attachment to a bone, taking a small chip of bone with it
Avulsion
central, stable portion of the skeletal system, consisting of the skull, spinal column, and thoracic cage
Axial Skeleton
small capsules lined with synovial membranes and filled with synovial fluid; they cushion the structures they separate
Bursae
dense, solid bone that covers the outer surfaces of all bones and is the main form of bone tissue in the long bones
Cortical Bone
injury that involves displacement of a bone from its joint socket
Dislocation
any break or disruption of continuity in a bone
Fracture
process of red blood cell formation and development
Hematopoiesis
Bands composed of collagen and elastic fibers that connect bones to other bones
Ligaments
process of bone formation
Ossification
degenerative disease of articular cartilage, characterized by pain, swelling, range-of-motion restriction, and stiffness
Osteoarthritis
specialized bone cells that build new bone tissue
Osteoblasts
Specialized bone cells that resorb bone tissue
Osteoclasts
mature bone cells
Osteocytes
reduced bone mass without the presence of a fracture
Osteopenia
condition in which bone mineralization and strength are so abnormally low that regular, daily activities can result in painful fractures
Osteoporosis
tissue band composed of collagen and elastic fibers that connects a muscle to a bone
Tendon
double-layered synovial structures surrounding tendons subject to friction given their position close to bones; secrete synovial fluid to promote free motion of the tendons during joint movement
Tendon Sheaths
interior, spongy bone with a porous, honeycomb structure
Trabecular Bone
