ARTICULATION | JOINT BTW BONES, BONES AND CARTILAGE, BONE AND TEETH |
3 TYPES BASED ON FUNCTION ( MOVEMENT) | FIBROUS - MOSTLY SYNARTHROSIS CARTILIGINOUS - AMPHIARTHROSIS SYNOVIAL - DIATHROSIS |
MOSTLY SYNARTHROSIS JOINTS | IMMOVABLE , W/OUT NO JOINT CAVITY MOSTLY AXIAL |
AMPHIARTHROSIS JOINTS | SIGHTLY MOVABLE, NO JOINT CAVITY MOSTLY AXIAL |
DIARTHROSIS | FREELY MOVABLE, SYNOVIAL CAVITY & SYNOVIAL MEMBRANE MOSTLY APPENDICULAR |
FIBROUS - MOSTLY SYNARTHROSIS EXAMPLES OF JOINTS | SUTURES, GOMPHOSE, SYNDESMOSE |
SUTURE | IMMOVABLE JT BTW CRANIAL BONES |
GOMPHOSE | BTW TOOTH AND ALVEOLAR SOCKET |
SYNDESMOSES | DISTAL TIBIA/ FIBULAR JT CONNECTED BY LIGAMENTS SLIGHTLY MOVEABLE |
CARTILIGINOUS - AMPHIARTHROSIS JOINT EXAMPLES | SYMPHYSIS, SYCHONDROSE |
SYMPHYSIS | FIBROCARTILAGE: PUBIS SYMPHYSIS, INTERVERTEBRAL DISC RESIST TENSION AND COMPRESSION |
SYCHONDROSE | BTW COSTAL CARTILAGE OF 1ST RIB & MANDURBRIUM CONNECTED BY HYALINE CARTILAGE FUNCTIONALLY IMMOVABLE |
SYNOVIAL JOINT | BONE ENDS COVERED BY ARTICULAR (HYALINE) CARTILAGE, ARE BEST AT ABSORBING COMPRESSION |
SYNOVIAL JOINT MADE UP OF | SYNOVIAL CAVITY, ARTICULAR CAPUSLE ( INNER & OUTER), ARTICULAR DICS (MENISCI), BURSA SACS, LIGAMENTS |
SYNOVIAL CAVITY | SPACE W/ SYNOVIAL FLUID |
ARTICULAR CAPSULE | ENCLOSES CAVITY AND BONE ENDS 2 LAYER -OUTER - FIBROUS, STRENGTH, CONTINUOUS W/ PERIOSTEUM -INNER- SYNOVIAL MEMBRANE, PRODUCES SYNOVIAL FLUID NOURISHES, LUBRICATES JOINTS |
BURSA SACS | CUSHION JOINTS; REDUCE FRICTION IN ELBOW, KNEE,SHOULDER LINED BY SYNOVIAL MEMBRANE - FILLED W/ SYNOVIAL FLUID |
LIGAMENTS | CAPSULAR, EXTRACAPSULAR, INTRACAPSULAR |
CAPSULAR | DERIVED FROM ARTICULAR CAPSULE |
EXTRACAPSULAR | OUTSIDE CAPSULE: MEDIAL, LATERAL COLLATERAL LIGAMENT |
INTRACAPSULAR | INSIDE CAPSULE: ANTERIOR, POSTERIOR CRUCIATE LIGAMENT |
