Which type of anatomical section could be used to separate the thoracic cavity from the abdominopelvic cavity?

• A. Oblique section
• B. Coronal (frontal) section
• C. Transverse (horizontal) section
• D. Sagittal section

Answer: (C)

Verified step by step guidance

1. Understand the anatomical regions involved: The thoracic cavity houses organs like the lungs and heart, while the abdominopelvic cavity contains organs such as the stomach, intestines, and liver. These two cavities are separated by the diaphragm.
2. Review the types of anatomical sections: Anatomical sections are planes used to divide the body. The options provided include oblique, coronal (frontal), transverse (horizontal), and sagittal sections.
3. Define each section: An oblique section cuts at an angle, a coronal (frontal) section divides the body into anterior and posterior parts, a transverse (horizontal) section divides the body into superior and inferior parts, and a sagittal section divides the body into left and right parts.
4. Determine the correct section for separating the thoracic cavity from the abdominopelvic cavity: Since the thoracic cavity is superior to the abdominopelvic cavity, a transverse (horizontal) section is the appropriate choice to divide these regions into superior and inferior parts.
5. Conclude that the transverse (horizontal) section is the correct anatomical plane to separate the thoracic cavity from the abdominopelvic cavity, as it aligns with the superior-inferior division required.
