beginning
In this article, I will explain effective study methods, starting with knowledge of specialized parts 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.
I hope you will deepen your understanding even a little by reading this article and using the app.
Now, I will explain the contents of “lateral cricoid lanceolate muscle/posterior cricoid lanceolate muscle” and how to study human anatomy.

What are lateral cricoid lanceolate muscle and posterior cricoid cleft muscle?
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 lateral cricoid muscle
The lateral cricoarytenoid muscle (lateral cricoarytenoid muscle) is an important muscle involved in vocal cord movement and vocalization. This muscle originates from the outside on the upper side of the cricoid cartilage and is inserted into the musculature of the apical cartilage.
Its main function is to rotate the apical cartilage and invert (move inward) the vocal cords. This causes the vocal cords to touch each other, closes the glottis, and produces sound. It also plays a role in preventing food or drink from accidentally entering the trachea.
The lateral cricoid lanceolate muscle is essential to ensure proper closure of the vocal cords during speech. This muscle is innervated by the inferior laryngeal nerve of the vagus nerve (cranial nerve X), and impairment may cause difficulty speaking and breathing.
Study points
1. Using visual materials: Use detailed anatomical diagrams and 3D models to visually grasp the exact location and running of the lateral cricoid muscle. In particular, check the positional relationship between cricoid cartilage and apical cartilage. We also understand relationships with other laryngeal muscles and understand the overall laryngeal structure.
2. palpation: Direct palpation is difficult, but you can indirectly sense muscle contractions by speaking while touching the outside of the larynx. Be aware of the differences between breathing and speech, and observe laryngeal movements.
3. Movement observation: Use a mirror to observe how your larynx moves during speech. In particular, pay attention to the movement when the vocal cords close. Observe others' vocal movements and understand how the lateral cricoid muscle works.
4. Understanding features: Learn the specific roles and mechanisms of how the lateral cricoid lanceolate muscle rotates the lacerative cartilage and inverts the vocal cords. I also understand the importance of glottic closure during vocalization.
5. Learning clinical symptoms: Learn about the symptoms and treatments caused by lateral cricoid muscle disorders (e.g. nerve paralysis or muscle injury). Understand how dysphonia and breathing difficulties occur, and you'll also learn how to deal with them appropriately.
About posterior cricoid cleft muscle
The posterior cricoarytenoid muscle (posterior cricoarytenoid muscle) is one of the main muscles in the larynx, and is particularly responsible for controlling vocal cord movement during breathing.
This muscle originates from the outside of the cricoid cartilage and is inserted into the musculature of the apical cartilage. The main function of the posterior cricoid lanceolate muscle is to expand the glottis (space between the vocal cords) by rotating the lenticular cartilage and pulling the vocal cords outward.
This makes it easier for air to pass through the trachea and breathing can be carried out smoothly. The posterior cricoid cleft muscle is innervated by the inferior laryngeal nerve of the vagus nerve (cranial nerve X). If this muscle does not work properly, symptoms such as difficulty breathing and poor voice quality can occur.
Study points
1. Using visual materials: Use detailed anatomical diagrams and 3D models to visually understand the position and movement of the posterior cricoid cleft muscle. In particular, check the muscle path from cricoid cartilage to apical cartilage. We will also understand relationships with other laryngeal muscles and anatomical structures.
2. palpation: Touch the outside of the larynx with your finger and observe the movement of the throat as you inhale and make a sound. Direct palpation is difficult, but it can be understood indirectly by sensing laryngeal movements.
3. Movement observation: Use a mirror to observe your throat movements as you breathe and speak. In particular, check the movement of the vocal cords to open and close. Observe others' movements to understand how the posterior cricoid muscle works.
4. Understanding features: Learn how the posterior cricoid cleft muscle rotates lenticular cartilage and widens the glottis and its specific role. Understand the role of the glottis in breathing and vocalization.
5. Learning clinical symptoms: Learn about symptoms and treatment methods for posterior cricoid muscle disorders (e.g. nerve paralysis or muscle injury). Understand the causes and treatments for breathing difficulties and dysphonia.
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.
