Dissecting the New Anatomy Content in the Wolfram Language
The human body has been a subject of study since the earliest days of human history. The modern scientific fields of anatomy and physiology stem from the Renaissance symbiosis of art and anatomy. In the early 1500s, Leonardo da Vinci was among the first to accurately sketch bodily structures. In 1543, Andreas Vesalius published the famous textbook De Humani Corporis Fabrica (On the Fabric of the Human Body) with beautiful illustrations of the human body.
With modern technology at our disposal, we can take anatomy and physiology off the page and digitally put it into a readily computable format. Through Wolfram|Alpha, we are making it possible for you to gain further insight into how individual anatomical structures interplay in the human body and explore it from entire organ systems down to microscopic ganglia.
Let’s begin our exploration with a macroscopic structure.
A vital organ of the cardiovascular system, the heart:
Wolfram|Alpha not only provides the basic information of the anatomical structure (Latin name, function, group, parts, etc.), but also computes relations and connectivities of anatomical structures.
The “arterial supplies of the heart”, for example, are:
Making a comparison of two large vessels of the cardiovascular system can be done just as easily.
“Aorta vs. inferior vena cava”:
Anatomical structure data is also accessible via the Wolfram Language.
Let’s start out with the musculoskeletal system. Whether you are a gymnast or someone who takes regular trips to the local gym, you may want to build your leg muscles. Which muscles are those? The Wolfram Language can provide a list of muscles that are part of the leg:
Now let’s look at a major muscle of the leg you use during exercise, the gastrocnemius muscle.
The muscle origin (its fixed end) and insertion (its movable end) are:
We now know that the gastrocnemius muscle attaches to the femur and calcaneus bones. But where are these in the lower limb (a.k.a. foot, leg, thigh, and hip)?
Wow, that’s a lot of bones! How can we see the forest for all these trees? Let’s find out how they articulate:
We can see five toes on the right and the leg and thigh on the left. Can we find out the names of the bones in between?
Knowing which bones connect to each other is helpful. Can we find the calcaneus and the femur and see what they look like?
How big is the calcaneus bone? Going even further, you can find out the volume of the calcaneus:
Let’s assume after an hour of running on the treadmill, which according to Wolfram|Alpha burns about 946 calories (assuming the pace of an average male, about 8 min/mi), you might receive a signal of hunger from your brain and eat a bar of chocolate to make up for it.
Pressing Control plus = and typing “digestive organs” gives a representation of the major organs of the digestive system:
Get a list of digestive organs and find out what they do:
Use WordCloud to visualize the words most frequently used to describe digestive functions:
These digestive activities are an unconscious process regulated by our autonomic nervous system.
Find out which nerves innervate these digestive organs:
The vagus nerve and its branches in the autonomic nervous system control gastric activities in your digestive system .
After you eat the bar of chocolate, your blood glucose level goes up. As a result, your pancreas secretes insulin:
This hormone, among others, signals the nuclei of the hypothalamus that you have eaten; in turn, the nucleus decides when you are full :
How do they influence one another?
Let’s make a picture out of these associations:
The paraventricular nucleus of the hypothalamus (red) is associated with appetite regulation , and you can see its projections to brainstem areas, which serve gastrointestinal functions.
Lastly, let’s take a look at where to find this nucleus. The paraventricular nucleus of the hypothalamus is in the left hemisphere of your brain, located very much in the center:
Whether anatomy is part of your daily work or just a casual interest, computable anatomy data can offer you an easier and deeper understanding of how human body parts relate to one another.

Is it possible to export to STL for 3D printing?
Is it possible to morph the shapes of these structures? For example, what if we want to approximate a deformity or surgical outcome?
I really love the way with computer graphics you can add and remove items, like muscles, ligaments and bones on the anatomical reproductions, the ability to go in close and expand areas is also extremely interesting, as is the ability to isolate organs as with the heart in the first image.
