Honors Anatomy & Physiology
What is an Articulation?
 Where two bones
interconnect
 Structure of joint
determines
movement.
 Designed to meet the
strength and flexibility
required for
movement.
Classification of Joints
 Synarthrosis
No movement
Can be fibrous or
cartilaginous.
Bones may fuse over
time.
Examples
Sutures
Synchondrosis:
growth plates
Classification of Joints
 Amphiarthrosis
Little movement
Can be fibrous or
cartilaginous.
Examples
Symphysis
Syndesmosis
Classification of Joints
 Diarthrosis
Synovial joints
Free
movement/planes
Examples
Hinge
Ball-and-socket
Gliding
Accessory Structures
 Ligaments
Support, strengthen,
reinforce synovial joints.
 Fat Pads
Localized adipose tissue
to cushion joints
 Cartilage
Meniscus
Articular discs
 Bursae
Fluid-filled pocket
 Tendons
Muscle attachment
Passes over joint to
provide support
