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, parasagittal, coronal, and transverse planes.

Define the sagittal plane: The sagittal plane divides the body into right and left portions. If the division is exactly in the middle, creating equal right and left halves, it is called the midsagittal plane.

Define the parasagittal plane: The parasagittal plane is similar to the sagittal plane but divides the body into unequal right and left portions. It does not pass through the midline.

Compare the options provided: Analyze each option to determine which one matches the definition of a parasagittal plane. The correct description is 'A plane that divides the body into unequal right and left portions.'

Conclude the reasoning: Based on the definitions and comparison, the parasagittal plane is best described as dividing the body into unequal right and left portions, distinguishing it from the midsagittal plane and other anatomical planes like coronal and transverse.
