What is the vagus nerve?
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. This time, I'll explain using an anatomy application.
About the vagus nerve
The vagus nerve, also called the tenth cranial nerve, plays a very important role in the central nervous system. The vagus nerve leaves the brain, extends to the neck, chest, and abdomen, and provides a path for transmitting signals to many organs. This nerve is part of the parasympathetic nervous system where the body performs regulatory functions, and adjusts various physical functions such as heart rate, digestion, sweat secretion, and laryngeal muscle movement. Also, the vagus nerve is related to vocal cord movements and reflexes, and helps the process of making a voice and swallowing. The vagus nerve is also important for managing stress, and by being stimulated through relaxation activities such as deep breathing and meditation, it promotes a state of relaxation. This process causes physical changes, such as decreased heart rate and enhanced digestion. Furthermore, the vagus nerve is involved in the immune system and regulation of inflammation, and has a role in mitigating inflammatory responses in the body. Thus, the vagus nerve connects various parts of the body and plays an important role in maintaining normal physical function.
Study points
Location and structure of the vagus nerve
The vagus nerve is a very long nerve that extends from the brain to the whole body, and is one of 12 pairs of cranial nerves. It starts in the part of the brain called the medulla oblongata, passes through the neck, and spreads from the chest to the abdomen. This nerve innervates many important organs, and is named “vagus” because of its extensive pathways. Anatomically, the vagus nerve exits the skull near the base of the skull and descends while adjoining the internal carotid artery and jugular vein in the neck. When it enters the chest, it is involved in the heart, lungs, and trachea, then descends further and affects digestive organs such as the stomach and intestines in the abdomen. Due to this pathway, the vagus nerve is intricately involved in many different organ systems and helps coordinate various functions. There are two pairs of vagus nerves on the left and right, and although there are slight differences in pathways between left and right, they have a common basic structure and function. Due to its close connection, it affects various parts of the body and plays a role in transmitting various information.
The role and function of the vagus nerve
The vagus nerve has a wide range of roles in coordinating various important functions in the body. It mainly works as part of the parasympathetic nervous system and is characterized by promoting a relaxed state. It helps maintain a state of rest by reducing heart rate and regulating blood pressure. It also supports food digestion and nutrient absorption by boosting digestive system activity. Signals are sent to the stomach and small intestine to promote secretion of digestive juices, and peristalsis is adjusted. Furthermore, the vagus nerve is involved in the immune system and inflammatory response, and has the effect of suppressing inflammation in the body. This contributes to regulating the body's response to colds and stress. It also controls vocal cord movement and helps with vocalization and reflex functions (such as swallowing movements). In addition, it affects psychological states as part of the “gut-brain axis,” which connects the brain and intestines, and also contributes to stress and psychological health. In this way, the vagus nerve plays an important role in supporting a wide range of functions.
English notation for vagus nerve
The vagus nerve is expressed as “Vagus Nerve” in English. The word “Vagus” comes from the Latin word “wanderer (wanderer)” and indicates that nerves extend from the brain to many organs. The vagus nerve is one of 12 pairs of cranial nerves, and is classified as the tenth cranial nerve (Cranial Nerve X) in digital numbering. This notation emphasizes its unique structure and pathway, and it means that it exits from within the skull and controls approximately 75% of the body's parasympathetic nerves. The fact that names in English are derived from Latin is part of traditional nomenclature in medicine, and by using standardized terms around the world, it is easier to communicate even between different regions and languages. In particular, in the fields of anatomy and physiology, such standard terms are widely used so that misunderstandings do not occur in medical communication. Thus, the English notation for the vagus nerve plays an important role, which is the key to correctly understanding its function not only in the field of anatomy, but also in many other situations.
How to study human anatomy
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.
