Question

which of the following is a correct directional term to describe the relative position of the hands to the arms? superficial distal anterior proximal question 27 a joint with one convex articulating surface and one concave articulating surface is a joint. condyloid saddle ellipsoid a and b plane

Explanation:

1. For the first question, in anatomical directional terms, "distal" means farther from the attachment point of a limb to the body. The hands are farther from the shoulder (attachment of the arm to the body) compared to the arm itself, so "distal" is the correct term to describe the position of hands relative to the arms. "Superficial" refers to closer to the surface, "anterior" to the front - side, and "proximal" to closer to the attachment point.
2. For the second question, a joint with one convex articulating surface and one concave articulating surface is a condyloid joint. A condyloid joint allows for movement in two planes (biaxial movement). A gliding joint has flat or nearly - flat articulating surfaces, a hinge joint allows movement mainly in one plane like a door hinge, and a pivot joint allows for rotational movement around a single axis.

Answer:

1. B. distal
2. A. condyloid
