2. Which of the following is CORRECT concerning the sagittal plane of the body?
a. Parallel to the median plane
b. Parallel to the frontal plane
c. Parallel to the horizontal plane
d. Parallel to the coronal plane
ANS: A
Feedback
A A sagittal plane is parallel to the median plane.
B A sagittal plane is NOT parallel to the frontal plane but perpendicular.
C A horizontal plane is perpendicular to the median plane. A sagittal plane is
parallel to the median plane. Thus a horizontal plane is perpendicular to a
sagittal plane.
