| synostosis bony joint; immovable | formed when gap between 2 bones ossifies and they become a single bone. |
| synarthrosis fibrous joint | or synarthrodial joint. point at which adjacent bones are bound by collagen fibers that emerge from one bone |
| serrate sutures wavy lines where bone edges interlock - coronal | sagittal and lambdoid sutures |
| plane (butt) sutures where two bones have straight | non-overlapping edges - palatine processes |
| synovial joint (diarthrosis) very movable | very prone to injury or disease |
| fibrous capsule an outer capsule outside the articular capsule | continuous with the periosteum of adjioning bones |
| bursa fibrous sac filled with synovial fluid | located between adjacent muscles where a tendon passes. It cushions muscles and helps tendons slide more easily |
| tendon (synovial) sheaths elongated cylindrical bursae wrapped around a tendon | seen esp. in a hand or foot |
| range of motion flexibility or degrees through which a joint can move; affected by structure of articular surfaces of the bones | the strength & tautness of ligaments & joint capsules; action of muscles and tendons |
| pivot joints flat or slightly concave/convex surfaces; bones slide over each other & have limited movement (carpals | vertebrae) |
| hinge joints monaxial joints - elbow | knee |
| radial abduction move thumb to form 90 degree angle with forefinger | in same plane |
| palmar abduction point thumb anteriorly | as if to grasp a tool |
| rotator cuff tendons of the shoulder muscles (supraspinatus | infraspinatus |
| shoulder bursae subdeltoid | subacromial |
| proximal radioulnar joint not for bending elbow | but for rotating forearem |
| patellofemoral joint formed by patella | patellar ligament & femur |
| knee bursae superficial infrapatellar | suprapatellar |
| talocrural joint ankle - has 2 articulations - medial joing between tibia and talus | and lateral joint between fibula and talus all enclosed in one joint capsule |
