Types of Synovial Joints Flashcards
joints in all parts of the body (19 cards)
allow a wide range of movement including flexion, etc.
Ball and socket joints
the articulating ends of the bones fit together like a hinge or door.
movement is restricted to flexion and extension
Hinge joints
the articular surfaces are flat or very slightly curved and glide over one another but the amount of movement is very restricted.
group of joints is the least moveable of all synovial joints
Gliding joints
allow a bone or a limb to rotate.
one bone fits into a hoop-shaped ligament that holds it close to another bone and allows it to rotate in the ring
Pivot joints
smooth, rounded projection on a bone and in a condyloid joint it sits within a cup-shaped depression on the other bone.
permit flexion, extension, abduction, adduction and circumduction
Condyloid joints
articulating bones fit together like a person sitting on a saddle
Saddle joints
is the site at which any two or more bones articulate or come together, meaning the ends or edges of the bones are held together by connective tissues
Joints
the bones forming these joints are linked with tough, fibrous material.
permits no movement
Fibrous joints
these joints rae formed by a pad tough fibrocartilage between the bones that acts as a shock absorber
Cartilaginous joints
characterized by the presence of a space or capsule between the articulating bones.
the ends of the bones are held lose together by a sleeve of fibrous tissue and lubricated with a small amount of fluid.
are the most moveable joint of the body
Synovial joints
shoulder and hip
Ball and socket joints
elbow, shoulder, knees
Hinge joints
between carpals & tarsal bones
Gliding joints
rotation of the head
Pivot joints
joints between the metatarsal and phalenges
Condyloid joints
base of the thumb
Saddle joints
Some joints allow flexibility and movement
Joints
Sutural ligaments - joints between skull bones
Periodental ligament - joint where healthy tooth cemented into mandible
Interosseous membrane - joint where the tibia and fibula in the leg are held together along their shafts
Fibrous Joints
Epiphyseal plate
Intervertebral disks
Symphisis pub
Cartilaginous joints
