Arthrology Flashcards
Fibrous joints
Immovable (coronal suture of the skull)
SYNCHONDROSIS
(Primary cartilaginous joint)
Temporary cartilaginous junction between epiphysis and diaphysis (shaft) of a growing (immature) bone
Bones are united by a plate or a bar hyaline cartilage, sometimes occur btwn ossification (bone tissue formation) centers
-1st rib & the manubrium sterni
Secondary cartilaginous joint (symphysis)
Fibrocartilaginous and hyaline joints (semi movable)
E.g. manubriosternal joint, intervertebral discs, pubic symphysis
Synovial joints (diarthrosis)
Articular surfaces of the bone are covered by a thin layer of hyaline cartilage separated by a joint cavity; great degree of freedom of movement
Synovial membrane
Lines cavity of the joint
Articular capsule / capsule only
Tough fibrous membrane outside, protects synovial membrane
Synovial fluid physical properties
Viscous, elastic, plastic components
Viscous fluid (found in joint cavity); HYALURONIC ACID is the main component
Plane joint (gliding joint)
Gliding or sliding movements
Acromioclavicular joint (at the top of the shoulder; junction btwn acromion and clavicle)
Plane joint
Sternoclavicular joints
Plane joint
Intercarpal joints (carpals of the wrist)
Plane joints
Subtalar/Talocalcaneal (intertarsal joint)
Plane joint
Vertebrocostal joint
Plane joint
Sacroiliac joint
Plane joint
A type of joint which restricts movement to one plane only (uniaxial) and possess strong collateral ligaments (Flexion and extension movements)
Hinge joint
