NEW: Explore our Five New 3D Detailed Models

Exciting news! Complete Anatomy is expanding once again, presenting five new detailed 3D models for your learning and teaching journeys. Dive deeper than ever into the intricacies of the human body. Are you ready to uncover more secrets of human biology? Let’s dive in together! 

Smooth muscle 

Smooth muscle is a type of muscle found in the walls of organs and blood vessels and in the skin. It supplies various involuntary functions to the areas it is present in. A user will be able to compare this model to other types of muscle cell models in CA such as the skeletal muscle. 


Spermatogenesis is the process of formation of spermatozoa in the testis. This model shows the progression of spermatogonium to full sperm cell by dissecting a portion out from the seminiferous tubules in the testis. This is a great compliment to our ovary model that shows the progression of oocytes to ovum. 

Small intestine 

The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. This model shows all three parts side by side. This allows users to compare and contrast the structures between each area. 


The pancreas is an accessory digestive organ with both exocrine and endocrine glandular components. The exocrine component of the pancreas is the part of the pancreas that acts as an exocrine gland, consisting of the pancreatic acini, which produces pancreatic juice and secretes it into the duodenum to aid in protein digestion. Pancreatic islets are irregular microscopic structures scattered throughout the pancreas and comprising its endocrine part. This model allows the user to distinctly see the different cell types that make up this structure and understand their secretions. 

Cell membrane 

The phospholipid bilayer is the structure common to all biological membranes, consisting of two layers of phospholipids. This model ties in well with our Eukaryotic cell model as they are the two main components to learning biology. With this model users can understand how structures move across the cellular membrane. 

The addition of these five new models once again pushes the boundaries of how we understand the human body, taking us beyond traditional learning into a visual and interactive experience. Learn how to access the five new detailed models, and let’s keep exploring together!
