intervertebral discexists between every vertebral body except atlas and axis
Two parts of intervertebral discsanulus fibrousis and nucleus pulposus
anulus fibrousis outer layer, tough, attaches disc to vertebral bodies
nucleus pulposuselastic, gelantous core, absorbs shock
slipped discanulus fibrosis is bulging out
herniated discnucleus breaks through anulus, presses on nerves
shoulder jointgreater movement, less stability, ball and socket joint
glenoid lubrumdeepens the socket of the shoulder and makes shoulder more stable, thin layer of fibrocartilage
shoulder dislocationhead of humerus and glenoid cavity
shoulder seperationacromial calvicular joint seperation

knee jointhinge joint, monaxial
articulations of knee jointfemur and tibia condyles, between patellar and patellar surfaces
medial and lateral meniscusfibrocartilage joint, make joint stable through flexion and extension, gives lateral support
extracapuslarfibial and tibial collateral ligaments
intracapusularanterior and posterior cruitiate ligaments
rehumatismpain of stiffness of skeletal and muscular systems
arthriitisloss of cartilage in synovial joints
osteoarthritiswear and tear, genetic factors effecting collagen formation, generally people over 60
