Chapter 1, Problem 21

A plane through the body that passes perpendicular to the long axis of the body and divides the body into a superior and an inferior section is a
(a) Sagittal section,
(b) Transverse section,
(c) Coronal section,
(d) Frontal section.

Verified step by step guidance

Step 1: Understand the anatomical planes of the body. The body can be divided into sections by imaginary planes that help describe locations and directions.
Step 2: Identify the long axis of the body, which runs vertically from head to toe.
Step 3: Recognize that a plane perpendicular to this long axis means the plane cuts horizontally across the body.
Step 4: Know the definitions of the planes: a sagittal plane divides the body into left and right parts; a coronal (or frontal) plane divides the body into anterior (front) and posterior (back) parts; a transverse plane divides the body into superior (upper) and inferior (lower) parts.
Step 5: Since the plane divides the body into superior and inferior sections and is perpendicular to the long axis, it corresponds to the transverse section.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Body Planes

Body planes are imaginary flat surfaces that divide the body into sections. They help describe locations and directions in anatomy, facilitating clear communication about body parts and their relationships.

Transverse Plane

The transverse plane is a horizontal plane that passes perpendicular to the long axis of the body, dividing it into superior (upper) and inferior (lower) parts. It is also called the horizontal plane.

Sagittal and Coronal Planes

The sagittal plane divides the body into left and right sections, while the coronal (or frontal) plane divides it into anterior (front) and posterior (back) sections. Understanding these helps distinguish the transverse plane from others.
