Which of the following best describes a sagittal plane?

• A. a horizontal plane that divides the body into anterior and posterior parts
• B. a horizontal plane that divides the body into superior and inferior parts
• C. a vertical plane that divides the body into anterior and posterior parts
• D. a vertical plane that divides the body into right and left parts

Answer: (D)

Verified step by step guidance

1. Understand the concept of anatomical planes: Anatomical planes are imaginary lines used to divide the body into sections. They are essential for describing locations and movements in the body.
2. Identify the types of anatomical planes: The main types are sagittal, coronal (frontal), and transverse (horizontal) planes.
3. Define the sagittal plane: The sagittal plane is a vertical plane that divides the body into right and left parts. It runs parallel to the median plane, which divides the body into equal right and left halves.
4. Differentiate between other planes: The coronal plane divides the body into anterior (front) and posterior (back) parts, while the transverse plane divides the body into superior (upper) and inferior (lower) parts.
5. Apply the definition to the problem: Based on the definitions, the sagittal plane is best described as a vertical plane that divides the body into right and left parts, which matches the correct answer provided.
