Chapter 7- Articulations Flashcards
Name and describe three classes of joints based on structure
Fibrous Joints: NO synovial cavity, and the bones are held together by fibrous CT (Rich in Collagen fiber).
Cartilaginous Joints: NO Synovial cavity, and the bones are held together by cartilage.
Synovial Joints: Bone forming joints HAVE synovial cavity, and are united by dense irregular CT

Hyaline cartilage that covers the ends of articulating bones
Articular cartilage
It lubricates the joints and nourishes the cartilage
Synovial Fluid
Inner layer of the articular capsule that produces synovial fluid
Synovial membrane
Pad of cartilage to help stabilize the joint
Meniscus
Together these form the articular capsule ( 2 ways)
Fibrous capsule
Synovial Membrane
Fluid- Filled sac that cushions movements
Bursa
The joint allowing for the greatest degrees of movement
Ball- and- socket
Flat surfaces of the carpals or tarsals move across each other
Gliding
The joint at the wrist between the radius and the carpals
Condyloid
Moves in a single plane at the knee or elbow
Hinge
The joint between the carpals and the metacarpals of the thumb
Saddle
The rounded head of the radios moves within the radial notch of the ulna
Pivot
Movement of a bone around its own axis
Rotation
Movement away from the midline of the body
Abduction
Palm faces upward or forward
Supination
Downward movement of a body part
Depression
Movement toward the midline of the body
Adduction
Movement of the mandible or shoulder backward
Retraction
Turning the palm so it faces downward or backward
Pronation
Upward movement of a body part
Elevation
Movement of a distal end of a body part in a circle
Circumduction
Beyond the plane of extension
Hyperextension
Movement of the sole of the foot inward
Inversion
Movement of the foot so the toes point downward
Plantarflextion
