Multiple Choice

If an incision cuts the heart into right and left parts, the section is a:

frontal (coronal) section

transverse section

oblique section

sagittal section

Verified step by step guidance

Understand the anatomical planes of the body: The sagittal plane divides the body into right and left parts, the frontal (coronal) plane divides it into front and back parts, and the transverse plane divides it into top and bottom parts. The oblique plane cuts at an angle.

Identify the direction of the incision described in the problem: The incision cuts the heart into right and left parts, which aligns with the sagittal plane.

Recall that the sagittal plane can be further divided into midsagittal (equal right and left halves) and parasagittal (unequal right and left parts). The problem does not specify whether the division is equal or unequal, so it is simply referred to as a sagittal section.

Compare the other options: A frontal (coronal) section would divide the heart into anterior (front) and posterior (back) parts, a transverse section would divide it into superior (top) and inferior (bottom) parts, and an oblique section would cut at an angle. None of these match the description of dividing into right and left parts.

Conclude that the correct answer is a sagittal section, as it is the anatomical plane that divides the heart into right and left parts.
