Is dorsiflexion a flexion or extension?
Dorsiflexion refers to flexion at the ankle, so that the foot points more superiorly. Dorsiflexion of the hand is a confusing term, and so is rarely used. The dorsum of the hand is the posterior surface, and so movement in that direction is extension.
What is retraction anatomy?
Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column. For the mandible, protraction occurs when the lower jaw is pushed forward, to stick out the chin, while retraction pulls the lower jaw backward.
What is a sporting example of dorsiflexion?
Dorsiflexion occurs in your ankle when you draw your toes back toward your shins. You contract the shinbones and flex the ankle joint when you dorsiflex your foot.

What are the two types of movements?
The different types of movement that are permitted at each joint are described below.
- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
- Adduction – movement towards the midline of the body.
- Circumduction – this is where the limb moves in a circle.
What is the difference between protrusion and retraction?
However, some anatomists today use protraction and retraction to refer almost exclusively to the scapulae, as it is a combined movement (protraction is anterolateral, and retraction is posteromedial). In contrast, protrusion and retrusion are more of an anterior/posterior movement.
Which is the correct medical definition of protraction?
Protraction is movement of a body part in the anterior direction ie. Proctraction retraction depression elevation upward and downward rotation. Medical definition of protraction. Retraction is the opposite motion with the scapula being pulled posteriorly and medially toward the vertebral column.
When does protraction of the scapula take place?
Protraction Anatomy. Protraction of the scapula occurs when the shoulder is moved forward as when pushing against something or throwing a ball. Protraction and retraction refer to an anterior protraction or posterior retraction movement.
Which is the opposite of the movement of retraction?
Opposition is the movement that involves grasping of the thumb and fingers. The movement of protraction is the opposite of the movement of retraction. Protraction is movement of a body part in the anterior direction ie. Proctraction retraction depression elevation upward and downward rotation. Medical definition of protraction.
