Question

question 3 of 25
the imaginary line created when the body is divided into equal right and left halves is called the ______.
a. midsagittal plane
b. dorsal plane
c. transverse plane
d. sagittal plane

Explanation:

To solve this, we analyze each option:

• Option a: The midsagittal plane (or median sagittal plane) is the imaginary line that divides the body into equal right and left halves.
• Option b: The dorsal plane (or posterior plane) is related to the back, not dividing into right/left equal halves.
• Option c: The transverse plane divides the body into upper and lower parts, not right/left.
• Option d: A sagittal plane divides the body into right and left, but a midsagittal plane specifically divides it into equal right and left halves (a sagittal plane can be off - center, while midsagittal is the midline). So the correct answer is a.

Answer:

a. midsagittal plane
