1. Articulations of the body

2. Articulation – A joint, or point of contact between bones
3 major categories based on function or structure.
For this class we will focus on structure.

3. 3 types of joints Fibrous
Joints with differing amounts of connective tissues. Some of these joints have limited movement but most are fixed and have no movement

4. 3 types of joints
Cartilaginous – Bones that articulate and are formed using hyaline cartilage or fibrocartilage.
These joints have very limited movement and usually only in certain circumstances.

5. 3 types of articulations
Synovial – freely movable joints. Most numerous and most complex joints.
Majority of the joints between bones in the appendicular skeleton are synovial
Examples – Elbow, knee, hip, shoulder, ankle, etc.

7. Type
Movement
Example
UNIAXIAL
Around one axis
Hinge
Flexion and Extension only
Elbow
Pivot
Rotation
C1 and C2
BIAXIAL
Around 2 Axes
Saddle
Flexion, extension in one plane; abduction/adduction in other
Thumb between 1st metacarpal and carpal
Condyloid
Flexion and extension in one plane; abduction/adduction in other
Joint between Radius and Carpals
Multiaxial
Many Axes
Ball and socket
Widest range of movements flexion/extension, abduction/adduction, rotation
Shoulder and Hip
Gliding
Gliding movements no angular or circular movements
Between vertebrae, between carpals, between tarsals
