MICROANATOMY

Detailed explanation-1: -In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension.

Detailed explanation-2: -Flexion/Extension The movement at a joint which decreases the angle between two adjacent body segments is know as flexion.

Detailed explanation-3: -Flexion is bending, such as at the elbow or knee, and extension returns us to anatomical position. With regard to the joints within limbs, flexion always decreases the angle between the articulating bones while extension increases the angle between the articulating bones, bringing us back to anatomical position.

Detailed explanation-4: -Answer and Explanation: The type of joint movement that increases the angle between the bones is called extension.

Detailed explanation-5: -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. When a person is sitting down, the knees are flexed.
