Question

What is the term that describes the central ray entering the anterior surface of the body and exiting the posterior surface?

a. Anteroposterior (AP)
b. Posteroanterior (PA)
c. Lateral
d. Oblique

Answer 1

Derived from directional terms, anterior (ventral) denotes the front, and posterior (dorsal) indicates the back of the body. An anteroposterior view in medical imaging, such as X-rays, captures a ray entering through the front and exiting through the back, providing a comprehensive perspective.

Step-by-step explanation:

This term is derived from the directional terms that define the relative positions of the human body. The anterior (or ventral) refers to the front or direction toward the front of the body, and the posterior (or dorsal) refers to the back or direction toward the back of the body. Therefore, when a ray enters through the front and exits through the back, it captures an anteroposterior view, commonly used in medical imaging like X-rays.
