Answer 1

Flexion, Circumduction, and Adduction are actions performed by muscles

Step-by-step explanation:

a. decreasing the angle between two bones: Flexion is the action or movement that decreases the angle between two bones. For example, bending the lower arm up towards the upper arm is an example of flexion.

b. swinging the arm around in a circle: Circumduction is the action or movement of swinging the arm around in a circle. It involves a combination of flexion, extension, abduction, and adduction.

c. moving a body part toward the midline: Adduction is the action or movement of moving a body part toward the midline. For example, moving the leg in toward the body is an example of adduction.
