Body planes and cavities
Fri, Feb 5, 2027 · Week 3 · Human Anatomy & Physiology (Human Body Systems)
Today's goal: Identify the body planes and major cavities and the organs each contains.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Planes (labeled on the figure):
- Sagittal plane: divides the body into left and right.
- Frontal (coronal) plane: divides the body into anterior (front) and posterior (back).
- Transverse plane: divides the body into superior (top) and inferior (bottom).
Cavities (labeled with one organ each):
- Dorsal cavity: cranial cavity holds the brain; spinal cavity holds the spinal cord.
- Ventral cavity: thoracic cavity holds the heart and lungs; abdominopelvic cavity holds the stomach, intestines, and bladder.
Quick reference I wrote on the page:
- Separate left from right: sagittal plane.
- Separate front from back: frontal (coronal) plane.
- Separate top from bottom: transverse plane.
| Cavity | Subdivision | Example organ |
|---|---|---|
| Dorsal | Cranial | Brain |
| Dorsal | Spinal | Spinal cord |
| Ventral | Thoracic | Heart, lungs |
| Ventral | Abdominopelvic | Stomach, intestines |
This model shows the level of evidence and organization needed to complete: A dated, labeled diagram identifying the three anatomical planes and the major body cavities, with at least one organ placed in each major cavity.
- Date and label the entry.
- Record the procedure, observation, or design decision clearly.
- End with what the evidence means and the next step.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: Submit a photo of your completed, dated notebook diagram.

Submit one PDF. Put your first and last name in the document header. Name the file: FirstName LastName - Assignment Title - YYYY-MM-DD.pdf.

Claim ceiling: Label planes by the portions they separate and place organs in the cavity your figure shows. A labeled diagram cannot show a real patient's organs, a mass, or which scan to order.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.
Tap an answer to see the full explanation. Nothing is recorded or graded.
It builds this reusable test skill: Naming the plane that divides the body into left and right.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
