In this article, I will explain effective study methods in human anatomy.
In human anatomy, it is necessary not only to memorize the names of various organs, muscles, and bones, but also to remember where they are located in the body. Therefore, it is necessary to learn as efficiently as possible.
This time, I will explain how to study about the “diaphragm.”

Learning using anatomy apps
The anatomy application allows you to view a selection of anatomy 3D models. In this model, there are various observation methods such as surfaces, cross-sections, and nervous systems.
1. Location of the diaphragm
The diaphragm is a very important muscle in the human body, and it is a structure that separates the chest cavity from the abdominal cavity.
Its position is just at the bottom of the ribs, and it is arranged in a dome shape connecting the left and right rib arches (the part where the ribs bend forward). This dome-shaped shape adjusts pressure in the chest cavity and abdominal cavity by rising and falling during breathing.
The chest cavity contains the lungs and heart, and organs such as the liver, stomach, and intestines fit in the abdominal cavity. As the diaphragm contracts, the chest cavity expands, and the lungs expand to facilitate breathing.
Conversely, when the diaphragm relaxes, the chest cavity narrows, and breathing ends as the lungs push air out.
By understanding this mechanism, knowledge about the mechanism of breathing and related pathologies will be deepened.
2. The constituent muscles of the diaphragm
The diaphragm is mainly composed of muscles and tendons. The diaphragm consists of the center of a strong tendon in the center and the muscles surrounding it.
The tendon center is located at the apex of the diaphragm, where the muscles converge. The surrounding muscles start from the sternum, ribs, and lumbar spine and run toward the center of the tendon upward.
Specifically, it has the following starting part. 1. Anterior side: The sternum is a muscle group starting from the xiphoid process. 2. Side: The ribs are muscle groups starting from the 7th to the 12th ribs. 3. Posterior side: The lumbar spine is a muscle group starting from the upper part of the lumbar spine (L1-L3).
As these parts repeatedly contract and relax, the diaphragm moves up and down, and breathing is promoted. Thus, the diaphragm has starting points in multiple skeletal parts, and each plays an important role by moving in cooperation.
3. Major nerves of the diaphragm
The primary innervation of the diaphragm is carried out by the phrenic nerve. The phrenic nerve starts from the cervical plexus (C3, C4, C5) and runs through the thoracic cavity to reach the diaphragm.
In particular, these nerve roots are so important to the diaphragm that they can be remembered as “C3, C4, C5 keep the diaphragm alive.”
The phrenic nerve contains sensory and motor nerve fibers, and transmits diaphragm movement and sensory information to the brain. Since these nerves function properly, breathing can be carried out smoothly.
If the phrenic nerve is damaged, serious problems such as difficulty breathing and paralysis of the diaphragm may occur. Therefore, understanding the anatomical pathways and regions of the phrenic nerve is critical for maintaining respiratory health.
Specific study methods using apps
I will explain specific study methods using human anatomy applications.
Check your past learning history and practice repeatedly
Here are the steps to check your anatomy learning history and practice iteratively effectively.
1. Check your learning history in the app
Reviewing your learning history with the application is an important step in effectively advancing anatomy learning. First, launch the app and go to the learning history section from the main menu. Many anatomy apps are designed to show your progress in the form of graphs and lists, so you can visually check which parts you've learned about and how much time you've spent.
By using this data, you can understand which areas you have strengths in and where you need to spend more time and effort. We also recommend using a dedicated tag or notebook function to mark areas you are particularly weak at or where you need to relearn. Regularly checking your learning history and looking back on past learning content will lead to efficient review and deepening understanding.
2. Make a plan for iterative learning
Making an efficient repetitive learning plan based on learning history is extremely effective in promoting knowledge retention. First, identify weak points and areas where you need to relearn. Next, arrange these study items into a weekly or monthly calendar and create a specific study schedule. By proceeding in a planned manner, you can learn each part evenly and avoid packing in a large amount of information at once.
Using a task management app or digital calendar to set study reminders is effective. Also, it's important to have the flexibility to regularly review progress and revise plans as needed. By having goals and proceeding with your studies in a planned manner, you can efficiently acquire anatomical knowledge.
3.Use 3D features to learn visually
By utilizing the 3D function, learning anatomy is easier to understand visually. The 3D model shows the structure of the human body three-dimensionally, and each part can be observed in detail. This makes it possible to intuitively grasp positional relationships between deep muscles and organs that are difficult to capture in a planar view. For example, you can learn even the smallest details by rotating specific muscles and bones and zooming in and out.
Also, there are many apps that have the function of displaying cross-sectional views of each part using a 3D model, which is useful for deepening understanding of internal structures. This diversity of visual information helps with memory retention and improves immediate responsiveness in tests and practice situations. By utilizing the 3D function and learning visually, you can learn anatomy knowledge more deeply and efficiently.
Use the memo function concretely
Make notes so you don't forget the things and points you've noticed while studying. The memo function can be used for different purposes, such as inputting text, saving images, and writing memos. Tag your notes to make them easier to review later.
Test your learning regularly in the form of quizzes
Regularly testing what you've learned in a quiz format is a very effective way to anchor your anatomy knowledge. Quiz-style tests help you objectively grasp your level of understanding and areas you lack while repeating knowledge.
For example, by using a learning app to conduct quizzes every specific period, you can reconfirm what you've learned and strengthen your memory. There are a wide range of quiz formats, such as multiple choice questions, fill-in-the-blank questions, and short answer questions, and each helps understanding from a different angle and develops the ability to utilize various types of knowledge.
Get feedback
If possible, get feedback from other learners and experts. It helps you find your own gaps in understanding and areas for improvement. You can also keep yourself motivated to learn by regularly testing yourself. Feeling a sense of accomplishment and progress increases motivation for continuous learning.
summary
This time, I explained how to study about the “diaphragm” using an application!
Thank you for reading this far.
I would be happy if reading this article helped you learn about anatomy.
Learning is a long, never-ending journey, but I sincerely wish you all the best. Let's continue to study together and work hard for the national exam!
Please look forward to the next blog.
