Pivot Joints are functionally classified as_______(in terms of its degree of movement) and why?
Uniaxial(monaxial) b/c only a single axis of movement)
Hinge Joints are functionally classified as_______(in terms of its degree of movement)and why?
Uniaxial(monaxial) type of joint/s, b/c ony a single axis of movement
Condyloid Joints (ellipsoid) are functionally classified as_______(in terms of its degree of movement)and why?
Biaxial joints b/c they allow two planes of movement
Saddle Joints are MOSTLY functionally classified as _________ Joints
HOWEVER some sources classify them as _________( ______or________)
Biaxial Joints
triaxial (polyaxial or multiaxial)
Plane Joints are functionally classified as…. But usually classified as?
