Test: Convex-concave rule (arthrokinematics)
20 questions
Question 1: In the shoulder joint, when the humerus, which is the convex surface, moves, the bone moves in the same direction as the surface.
A. Ano
B. Ne
Explanation: The study materials state that in the shoulder, when the convex surface (humerus) moves, the bone moves in the opposite direction.
Question 2: When a concave surface moves, the surface and the bone slide in the same direction.
A. Ano
B. Ne
Explanation: As explained in the study materials, when the concave surface moves, the surface and the bone slide in the same direction.
Question 3: The study material visually presents what a convex surface looks like.
A. Ano
B. Ne
Explanation: The study material states, 'Here is the concave surface and this is the convex surface,' indicating a visual presentation of both surfaces.
Question 4: The sole purpose of the convex concave rule is to differentiate between concave and convex joint surfaces.
A. Ano
B. Ne
Explanation: The study materials state that the 'Purpose of this rule is to understand the arthrokinematics.' While it does describe how to differentiate surfaces, that is not its sole purpose.
Question 5: When the convex surface moves, such as the humerus in the shoulder joint, the bone moves in the same direction as the surface.
A. Ano
B. Ne
Explanation: The study materials state that when the convex surface moves, as exemplified by the humerus in the shoulder, the bone moves in the opposite direction to the surface.
