Joints and Motion (Skeletal System) Flashcards
Articulating bones are fastened together by a thin layer of dense connective tissue
Fibrous joint
Articulating bones are connected by hyaline cartilage or fibrocartilage
Cartilaginous joint
Articulating ends of bones are surrounded by a joint capsule of ligaments and synovial membranes
Synovial joint
Ball shaped head of one bone articulates with the cup shaped cavity of another
Ball and socket joint
Oval shaped condyle of one bone articulates with elliptical cavity of another
Condyloid joint
Articulating surfaces are nearly flat or slightly curved
Gliding joint
Convex surface of one bone articulates with concave surface of another
Hinge joint
Cylindrical surface of one bone articulates with ring of bone and ligament
Pivot joint
Articulating surfaces have both concave and convex regions; the surface of the bone fits the complementary surface of another
Saddle joint
Bending parts at a joint so that the angle between them decreases and the parts come closer together
Flexion
Straightening parts at a joint so that the angle between them increases and the parts move farther apart
Extension
Movement at the ankle that brings the foot farther from the shin
Plantar flexion
Movement at the ankle that brings the foot closer to the shin
Dorsiflexion
Extension of the parts at a joint beyond the anatomical position
Hyperextension
Moving a part away form the midline
Abduction
