Articulations of the bodySlide2
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.Slide3
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 movementSlide4
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. Slide5
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. Slide6Slide7

Example
UNIAXIAL
Around one axis

BIAXIAL
Around 2 Axes
Saddle
Flexion,
extension in one plane; abduction/adduction in other
Thumb between 1
st
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
