Question

descriptions: flexion. flexion is a movement, generally in the ( 1. ) plane, that decreases the angle of the joint and brings two bones closer together (figures 6.13a and 6.13b). flexion is typical of ( 2. ) joints (bending the knee or elbow), but it is also common at ball - and - socket joints (for example, bending forward at the hip). extension. extension is the opposite of flexion, so it is a movement that ( 3. ) the angle, or distance, between two bones or parts of the body (straightening the knee or elbow). extension that is ( 4. ) than 180° (as when you move your arm posteriorly beyond its normal anatomical position, or tip your head so that your chin points toward the ceiling) is called hyperextension (figures 6.13a and 6.13b). rotation. rotation is movement of a bone around its longitudinal axis (figure 6.13c). rotation is a common movement of ball - and - socket ( 5. ) and describes the movement of the atlas around the dens of the axis (as in shaking your head “no”). o 1. increases 2. greater 3. joints 4. sagittal 5. hinge o 1. sagittal 2. hinge 3. increases 4. greater 5. joints o 1. hinge 2. increases 3. greater 4. joints 5. sagittal o 1. greater 2 joints 3. sagittal 4. hinge 5. increases o 1. joints 2. sagittal 3. hinge 4. increases 5. greater

Explanation:

Flexion generally occurs in the sagittal plane, is typical of hinge joints, extension increases the angle between body - parts, extension greater than 180° is hyperextension, and rotation is common in ball - and - socket joints.

Answer:

1. sagittal 2. hinge 3. increases 4. greater 5. joints
