The Anatomy of the Brain: An Introduction

Every species has its strengths. For cheetahs it’s their speed, for spiders their ability to spin webs. For humans, it’s our brains. We may not be the strongest or the quickest species on the planet, but we are the smartest, and that makes us able to invent creative solutions to all sorts of problems. The… Read more »

Illustrating Late-Onset Pompe Disease

Human beings are made up of cells—trillions of them, in fact—all working in concert to ensure that our bodies function properly. They convert food into energy, send signals from your brain to your body, and they form the tissues that make up our organs. They can even make copies of themselves using our own internal… Read more »

This Lanternfly From Southeast Asia Is a Sight to Behold

In addition to creating illustrations for legal exhibits and medical journals, I sometimes have an opportunity to study the anatomical structures of other species in my work as well. Such is the case in this illustration of a truly stunning insect that lives in Vietnam, Hong Kong, Laos, Thailand and other parts of Southeast Asia. Commonly… Read more »

The Elegant Simplicity of the Ball-and-Socket Joint

Did you know that there are six distinct types of synovial joints that all work together to provide the human body with its impressive range of motion? While some of these joints—like the gliding joint in the knee—are quite complex, the joints that grant us the greatest freedom of movement appear remarkably simple. In fact,… Read more »

Shaping Our World With the Human Hand

Long before humans became recognized as the animal kingdom’s predominant tool makers, our primate ancestors developed the five-fingered hands that would one day allow us to manipulate everything from prehistoric hammerstones to a spacecraft’s flight controls. With a complex structure that includes 27 bones, 29 joints and more than 100 distinct ligaments, our hands give… Read more »

Illustrating the Brainstem – The Core of Our Consciousness

Long before the prefrontal cortex gave humans the ability to express ourselves and engage in complex decision-making processes, our early ancestors were guided by a much simpler, more primitive brain. Today, we can still find evidence of this early brain buried deep beneath more recently-evolved structures like the parietal and temporal lobes of the cerebrum…. Read more »
