Verified step by step guidance

Understand the concept of anatomical planes: Anatomical planes are imaginary lines used to divide the body into sections for study and reference. Common planes include sagittal, midsagittal, parasagittal, transverse, and frontal (coronal).

Define the parasagittal plane: The parasagittal plane is a vertical plane that divides the body into unequal right and left portions. It runs parallel to the midsagittal plane, which divides the body into equal right and left halves.

Compare the parasagittal plane to other planes: The midsagittal plane divides the body into equal halves, while the parasagittal plane divides it into unequal portions. The transverse plane divides the body into superior (upper) and inferior (lower) portions, and the frontal plane divides the body into anterior (front) and posterior (back) sections.

Analyze the options provided: The correct description of the parasagittal plane is 'A plane that divides the body into unequal right and left portions, parallel to the midsagittal plane.' This distinguishes it from the midsagittal plane, transverse plane, and frontal plane.

Conclude the reasoning: Based on the definitions and comparisons, the correct answer is the option that describes the parasagittal plane as dividing the body into unequal right and left portions, parallel to the midsagittal plane.
