Effects of Flexion Movement on Human Body
What is flexion movement and how does it affect the human body?
Choose the correct statement:
a) Flexion is a bending movement in which the relative angle between two adjacent segments decreases.
b) Extension is a bending movement in which the relative angle between two adjacent segments decreases.
c) Abduction is a bending movement in which the relative angle between two adjacent segments decreases.
d) Adduction is a bending movement in which the relative angle between two adjacent segments decreases.
Answer:
Flexion is a movement that decreases the angle between two bones at a joint, distinctive from extension which increases the angle. The correct statement about flexion is that it decreases the bone angle.
Explanation:
During the process of flexion, the angle between two bones at a joint is decreased. This bending movement is commonly observed when you bring your forearm upward at the elbow. Conversely, extension refers to an increase in the angle between the bones, straightening the joint. It's essential to differentiate flexion from other movements such as abduction, which moves a limb away from the body's midline, and adduction, which brings it toward the midline.
In the context of your question, the correct statement about what happens during flexion is that the angle between bones is decreased (Option a).
