What does a complex synovial joint have that a simple and compound do not and what are two examples a meniscus is present, knee or acromioclavicular joint
What are the four types of movement for synovial joints translocation movement, uniaxial movement, biaxial movement/joints, multiaial movement/joints
What is a translocation movement gliding movement
What type of synovial joint has translocation movement plane joint or gliding joint
What are the 9 types of gliding diarthrodial joints intercarpal, intertarsal, intervertebral, costovertebral, Sternocostal(except rib 1 immovable), sternoclavicular, acromioclavicular, tibiofibular, Temporomandibular(hinge and gliding)
intercarpal and intertarsal joints are diarthrodial ________ diarthrodial gliding joints
intervertebral and costovertebral joints are diarthrodial __________ diarthrodial gliding joints
sternocostal joints (except rib 1 immovable) are diarthrodial __________ diarthrodial gliding joints
sternoclavicular and acromioclavicular joints are diarthrodial _______________ diarthrodial gliding joints

What specific synovial joint occurs in the transverse axis to the body with uniaxial movement ginglymus or hinge joint
Two characteristics of ginglymus joints movement is back and forth in one plane, movement is limited to flexion and extension because strong colateral ligaments are present
