The asexual trunk model is a basic anatomical model often used in medical teaching and clinical training. Its most prominent feature is the removal of gender characteristics, while only the main anatomical structure of the human trunk is retained. This model usually includes organs in the thoracic cavity, abdominal cavity and some pelvic cavities, such as the heart, lungs, liver, stomach, kidneys, intestines, etc. It can be disassembled for observation, which is convenient for learners to systematically understand the internal structure of the human body from the whole to the part.

By using the asexual trunk model, students can intuitively grasp the morphology, position and interrelationship of organs, especially when learning about the digestive, respiratory, urinary and circulatory systems, it has strong intuitiveness and practicality.

Meanwhile, this model is also frequently used in classroom demonstrations of nursing, anatomy and basic medicine to assist teachers in providing systematic explanations. Due to the elimination of gender differences, the asexual trunk model is more universal and suitable for most basic teaching scenarios. It not only avoids unnecessary embarrassment but also highlights the scientific and objective nature of anatomical learning. It is not only an important teaching aid in medical education, but also a crucial tool for helping learners establish a holistic and systematic view of the human body.
