2. decreases

3. increases

4. toward

5. away

6. around

7.  inward

8. outward

Explanation:

he Synovial joints are the joints which allow the movement of the body parts. The type of movement is determined by its structural type in which flexion and extension motions takes place in the anterior-posterior plane. In the limbs, the flexion decreases the angle in the bones while extension increases the angle between the bones.  

The abduction- adduction motions involve the medial-lateral motions of the bones in which Abduction moves the limb away from the midline of the body while adduction moves limb toward the midline.

Circumduction is the movement of a body region in a circular manner while rotation is the movement of the body part around its own axis.

Inversion and eversion are the complex movements in which inversion is the turning of the foot toward the midline or inward movement while eversion is reverse of this.

Thus, the selected options are the correct answer.
