Verified step by step guidance

Understand the term 'flexion': Flexion refers to a movement that decreases the angle between two bones at a joint, bringing them closer together. It is a common movement in joints like the elbow, knee, and fingers.

Analyze the options provided: The first option states that the angle between two bones decreases at a joint, which aligns with the definition of flexion. The other options describe movements that are not related to flexion.

Clarify the incorrect options: The second option, 'The limb moves away from the midline of the body,' describes abduction, not flexion. The third option, 'The limb rotates around its longitudinal axis,' refers to rotation. The fourth option, 'The angle between two bones increases at a joint,' describes extension, which is the opposite of flexion.

Relate flexion to anatomical examples: For instance, bending the elbow to bring the forearm closer to the upper arm is an example of flexion. Similarly, bending the knee to bring the lower leg closer to the thigh is another example.

Conclude the correct answer: Based on the definition and anatomical examples, the correct statement about flexion is 'The angle between two bones decreases at a joint.'
