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 can read this article and use the app to deepen your understanding even a little bit.
Now, I'll explain the details about the “perineal nerve” and how to study human anatomy.

What is the perineal 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 perineal nerve
Study points
Location and structure of the perineal nerve
The perineal nerve has a central position in pelvic floor anatomy, and its path is very important. First, the beginning is the sacral plexus, and specifically it comes out from S2-S4. This nerve passes through the pelvis, just above the large scar on the ischial bone, and near the small sciatic foramen. While following this path, the perineal nerve forms part of a major pathway known as the pudendal nerve. The perineal nerve is divided into several subdivided branches within its structure. Typical branches include the inferior rectal nerve, perineal nerve, and dorsal penile nerve or dorsal clitoral nerve. The inferior rectal nerve innervates sensation around the anus, the perineal nerve controls the skin and muscles of the perineum, and the dorsal penile or clitoral nerve provides genital sensation. Anatomically, the perineal nerve and its branches innervate the pelvic floor muscle group, and are particularly stretched over the urethral sphincter, anal sphincter, and other related muscles. This makes it play a decisive role in regulating urination and defecation, and even maintaining sexual function. Also, due to anatomical positional relationships, when the perineal nerve is damaged, symptoms such as pain and numbness in excretory function and sexual sensation may appear. Therefore, understanding pelvic floor anatomy is very important in related medical care.
The role and function of the perineal nerve
The perineal nerve is responsible for various functions, and in particular plays an important role in pelvic floor function and sexual function. First, sensory function controls sensation around the anus, vulva, and perineum, and accurately detects changes in pressure, pain, and temperature applied to the skin. As a result, the sensation during excretion and pleasure during sexual activity remain normal. As for motor function, the perineal nerve is essential for controlling the movement of pelvic floor muscles such as the anal sphincter and urethral sphincter. These muscles are essential, especially during defecation and urination, and proper contraction and relaxation of the sphincter allows excretion function to be performed smoothly. Also, this nerve is greatly involved in sexual function. Specifically, it plays a role in transmitting sensation to sexual stimulation through innervation to the penis and clitoris. This allows the process of sexual arousal to take place normally and sexual function is maintained. Thus, damage to the perineal nerve can result in poor sexual sensation and difficulty arousing. In addition, the perineal nerve is also important in controlling urination and defecation. These functions secure neural pathways that transmit sensory information to the brain, and at the same time perform motor control of the corresponding muscles. Therefore, when nerve damage or impairment occurs, problems such as incontinence, constipation, frequent urination, or overactive bladder may occur. Through these diverse roles, the perineal nerve is essential for maintaining normal daily life, particularly functions related to excretion and sex, and maintaining its health is medically important. It is also in this context that appropriate preventive measures and treatments are needed.
English notation for perineal nerve
The perineal nerve is called the “pudendal nerve” in English. This name is derived from Latin, and comes from the fact that “pudenda” has the meaning of “vulva.” The word “puddle” itself is a Latin word meaning “embarrassment” or “pubic area,” and it has a history where it was often used to indicate vulva. The name of this nerve reflects its anatomical position and function, and indicates that it controls the senses and movements associated with the pelvic floor and vulva. This naming of the nervous system is particularly important as a medical term and facilitates communication between health care professionals. In the name, it is required to clearly express the target part and its related functions, and this is summarized in the word “pudendal.” This naming, which is based on an anatomical point of view, is very important to ensure uniformity in medical settings and academic research, and to avoid confusion in diagnosis and treatment.
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
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.
