APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -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. Extension – straightening a joint.

Detailed explanation-2: -Flexion is the anatomical name for forward bending. When treating back pain, many spine specialists encourage exercises to strengthen the muscles that act to bring the spine into flexion. In the lower back, approximately 50% of flexion occurs at the hips, and 50% occurs at the lower spine.

Detailed explanation-3: -In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint.

Detailed explanation-4: -Flexion is a bending movement that decreases the angle between a segment and its proximal segment. For example, bending the elbow, or clenching a hand into a fist, are examples of flexion.
