Question

Match each term with the correct characteristic given in the key. Key: a. closing the angle at a joint b. movement in all planes c. made of cartilage d. movement toward the body e. fluid-filled sac Flexion

Short answer

Flexion is best matched with characteristic (a) closing the angle at a joint, as it involves bending and decreasing the angle between two body parts.

Step-by-step solution

Understand the term "Flexion"

Flexion refers to the bending or decreasing of the angle between two body parts. This usually happens when there is movement at a joint, causing the bones to move closer together. Step 2:

Match Flexion with the correct characteristic

Now that we know what Flexion means, we can examine the given key and choose the characteristic that best defines it. a. closing the angle at a joint - This characteristic seems to match the definition of Flexion as it involves bending and decreasing the angle between two body parts. b. movement in all planes - Flexion does not necessarily involve movement in all planes, as it is a specific type of movement. c. made of cartilage - This characteristic does not describe Flexion, as it is a type of movement and not a structural component. d. movement toward the body - Flexion might involve movement towards the body, but this characteristic does not capture the essence of Flexion as it refers to the bending or decreasing of the angle at a joint. e. fluid-filled sac - This characteristic does not describe Flexion, as it is a type of movement and not an anatomical feature. #Conclusion#: Based on our analysis, the correct characteristic that matches the term "Flexion" is: a. closing the angle at a joint
