38 Cards in this Set

  • Front
  • Back
(a band or ligament)
A fibrous joint connected by a ligament
(distal articulation between tibia and fibula)
Syndresmosis
A rigid cartilaginous connection between bones of the same skeletal element
(epiphyseal plate)
synchondrosis
Between teeth and jaws
Gomphosis
Where bones interlock
(skull sections)
suture
Free movement joints
Diathrosis
Joints that allow little movement
right and left halves of pelvis, between adjacent vertebrae
Amphiarthrosis
A joint that does not permit movement
(sutures)
synarthrosis
Joints
Articulations
An increase in the angle between articulating bones
extention
Movement in the anterior-posterior plane that reduces the angle between the articulating elements.
Flexion
Ossification of existing hyaline cartilage.
Endochondrial Ossification
Protein and mineral components are removed and replaced.
Remodeling
Beginning in embryonic or fetal connective tissue or fibrous connective tissue.
Intramembranous Ossification
The process of replacing other tissues within the bone.
Ossification
Production of new bone
Osteogenesis
Release of stored minerals
resorption
Helps regulate calcium and phosphate
Osteolysis
Cells responsible for production of new bone
Osteoblast
Giant cells with 50 or more nuclei
Disolve bony matrix
Osteoclast
Spongy bone - No osteons. Instead these are formed in rods or plates.
Trabeculae
Haversian canal - contain one or more blood vessels.
Central Canal
Basic functional unit of compact bone.
Osteon
Small channels radiating through the matrix - interlocking lacunae and linking them to blood vessels.
canaliculi
Narrow sheets of calcified matrix
Lamellae
Small pockets containing osteocytes.
Lacunae
Bone cells in both compact and spongy bone
Osteocytes
cellular lining inside bone
endosteum
Outer surface of bone
periosteum
Expanded ends of long bones
epiphysis
Long bones central shaft
diaphysis
Bone
A supportive connective tissue - contains specialized cells and matrix of extracellular protein fibers and ground substance
Osseous Tissue
Small pockets of connective tissue containing synovial fluid
*reduce friction
*shock absorbers
Bursae
Protect the articular cartilages and act as packing material
Fat Pads
Shock absorbing fibrocartiage pads
Menisci
(Surrounding joint) fibrous Inner surface of joint capsule lined with synovial membrane
Joint Capsule
fluid within the joint cavity providing lubrication that reduces friction between moving surfaces in joint.
Synovial Fluid
Fibrous joint covering where two bones meet
Articular cartilage
Permit wide range of movement
Synovial Joints
Cartilaginous joint separated by fibrocartilage pad
(Between right and left halves of pelvis)
Symphysis
