Definition
  • Shoulder, hip--ball & socket--**greatest range of motion
  • Elbow--hinge joint-allows medial, lateral, flexion and extension.
  • Knee--modified hinge--allows for only flexion & extension
  • Wrist--condyloid or ellipsoid joint--allows hyper extend, lateral & medial extension. (medial toward, lateral away)
  • Ankle--hinge joint-allows medial, lateral, flexion & extension

 

Term

Definition

Ball & Socket 

Hinge

Gliding

Saddle

Ellipsoid

Pivot

 

Term
Ball & Socket
Definition
greatest mobility- movement in all planes. One surface spherical and the other cupped: ex: hip & shoulder.
Term
Hinge
Definition
 flexion & extension in one plane. Ex: elbow & knee
Term
Gliding
Definition

 both surfaces flat, and allow limited movement. Ex: wrist & carpals

Term
Saddle
Definition
 allows movement in 2 planes, extension, flexion, abduction adduction, but not rotation. One surface concave and the other convex fitting together at the right angle. Ex: thumb
Term
Ellipsoid
Definition

 similar to ball & joint, allow same type of movement to a lesser magnitude. Ex: wrist

 
Term
Pivot
Definition
Ring around a peg, bone that rotates around another: rotation like the head over the shoulder 
Term
Invertebral Joints
Definition
located between the vertebrae allowing limited mobility between individual vertebra but great stability to protect the spinal column.
