Protrusion, Retrusion. And Excursion Anatomy Quiz
1. Which term describes the side-to-side movement of the mandible?
a. Protrusion
b. Retrusion
c. Excursion
d. Protraction
The answer is c, excursion. Later excursion is the movement to the left or right side of the mandible, whereas medial excursion is the movement of the mandible toward the body’s midline.
2. Which term describes the forward (anterior) movement of a structure?
a. Protrusion
b. Retrusion
c. Excursion
d. Retraction
The answer is a. Protrusion refers to the movement of a structure in a forward direction. This most commonly involves the tongue, mandible, and lips.
3. Which term describes the backward (posterior) movement of a structure?
a. Protrusion
b. Retrusion
c. Excursion
d. Protraction
The answer is b, retrusion. Retrusion refers to the posterior movement of a structure, typically the lips, mandible (lower jaw), or tongue.
4. Protraction and protrusion can both be used to refer to the movement of the mandible in a forward direction.
a. True
b. False
The answer is a, true. Some anatomists refer to the forward movement of the mandible as protrusion, but some still call it protraction. However, some anatomists only use protraction when discussing the movement of the scapulae in an anterolateral direction. For testing purposes, use the terms your professor recommends using.
5. Which movement occurs when the mandible moves to the left?
a. Protrusion
b. Retraction
c. Lateral Excursion
d. Medial Excursion
The answer is c, lateral excursion. Lateral excursion means the mandible is moving to the left or right side, away from the body’s center. Medial excursion means the mandible is moving back toward the body’s midline.
