• Spin

• All of the above

What is arthrokinematics?

• study of human movement

• The manner in which adjoining joint surfaces move on each other during osteokinematic movement

• Forces causing movements

• Time, space, and mass aspects of the moving system

What does roll in joint mean?

• Rolling of joints and muscles together

• Joint going wrong way

• Rolling of one joint surface on another joint surface

• Rolling of muscles

What does slide/glide mean?

• A linear movement of a joint surface parallel to the adjoining joint surface

• Rolling of the one joint surface on another joint surface

• The rotation of the movable joint surface on the fixed adjacent surface

• All of the above

What does spin mean?

• All of the following

• A linear movement of a joint surface parallel to the adjoining joint surface

• The rotation of the movable joint surface on the fixed adjacent joint surface

• Muscles and joints spinning together

What do these joints do?

• Roll

• Slide/glide

• Spin

• All of the above

What is convex on concave?

• When a convex joint surface moves on a fixed concave joint surface, the roll and slide occur in opposite directions.

• When concave joint surface moves on a fixed convex joint surface, the roll and slide occur in the same direction.

• Describes how the differences in shapes of bone ends require joint surfaces to move in a specific way during joint movement.
