skeletal system functions
no joint cavity or connective tissue, little to no movement (e.g., sutures of the skull) -
Correct Answers -non-synovial joint
produces synovial fluid, has joint cavity and connective tissue (gliding, condyloid, hinge,
saddle, pivot, ball-and-socket) - Correct Answers -synovial joint
synovial; no axis of rotation, slides side-to-side, back and forth (e.g., carpals of the
hand) - Correct Answers -gliding joint
synovial; condyles of one bone fit elliptical cavities of another, one plane of motion (e.g.,
knee) - Correct Answers -condyloid joint
synovial; uniaxial; one plane of motion (e.g., elbow) - Correct Answers -hinge joint
synovial; one bone fits like a saddle on another; two planes of motion (sagittal, frontal)
(thumbs are only ones in body) - Correct Answers -saddle joint
