ANATOMY

Detailed explanation-1: -Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. In extension, the opposite of flexion, the angle between the bones of a joint increases. Straightening a limb after flexion is an example of extension.

Detailed explanation-2: -Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball.

Detailed explanation-3: -As previously mentioned, Circumduction is when the distal end of a segment of the body moves in a circular motion. For instance, when you perform arm circles, you are performing Circumduction.

Detailed explanation-4: -Abduction and Adduction Adduction focuses on moving a limb towards the midline of the body (medially). This type of movement can occur with the arm at the shoulder, digits, and thigh at the hip. An example of this movement is when someone is performing jumping jacks.
