APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The muscles that initiate extension in our body are known as extensor muscles. Extension is a straightening movement that increases the angle between two body parts. Straightening of the elbow, knee or bending the wrist and spine backwards are examples of extension.

Detailed explanation-2: -Extension The movement that is opposite to the flexion-it increases the distance between two bones or parts of the body.

Detailed explanation-3: -Extension is the opposite of flexion in that the angle between the bones of a joint increases. Straightening a limb after flexion is an example of extension.

Detailed explanation-4: -A muscle that causes flexion is known as a ‘flexor’. In the above example, the hamstrings were the flexor muscles. Extension – straightening. This occurs when the angle between the articulating bones is increased.

Detailed explanation-5: -Extension is the opposite of flexion, a straightening movement that increases the angle between body parts. For example, when standing up, the knees are extended. When a joint can move forward and backward, such as the neck and trunk, extension is movement in the posterior direction.
